Home Network

New communication service capabilities of mobile devices have boosted the apparition of ubiquitous multimedia scenarios where users could easily create ad hoc multimedia sessions by friendly providing their requirements and preferences. In order to dynamically create and deploy such ubiquitous multimedia systems, end-users require frameworks which allow them in a spontaneous manner to generate the required multimedia sessions. This work introduces an ontology based framework aimed at the configuration and deployment of multimedia services driven by user preferences. A case study is presented in order to illustrate the use of this framework in the context of extended home networks.

This paper proposes a new coupling solution for transmitting narrowband multicarrier power line communication (PLC) signals over medium voltage (MV) power lines. The proposed system is based on an innovative PLC coupling principle, patented by the authors, which exploits the capacitive divider embedded in voltage detecting systems (VDS) already installed inside the MV switchboard. Thus, no dedicated couplers have to be installed and no switchboard modifications or energy interruptions are needed. This allows a significant cost reduction of MV PLC implementation. A first prototype of the proposed coupling system was presented in previous papers: it had a 15 kHz bandwidth useful to couple single carrier PSK modulated PLC signals with a center frequency from 50–200 kHz. In this paper, a new prototype is developed with a larger bandwidth, up to 164 kHz, thus allowing to couple multicarrier G3-PLC signals using orthogonal frequency division multiplexing (OFDM) digital modulation. This mo...

Personal Network (PN) is a user-centric concept to realize the interconnection of the users' various devices and networks, such as home networks, corporate networks and vehicle area networks, at any time and any place. These networks may be geographically separated from each other and are usually organized in an ad hoc fashion, where the devices in one network can share content, data, applications and resources with each other, and communicate with the outside world. Clustering for personal networks intends to organize these ad-hoc networked heterogeneous devices into hierarchical clusters. A new clustering scheme, Personal Network Clustering Protocol (PNCP), is proposed for PNs and compared with clustering algorithms in the literature in terms of various performance metrics. PNCP performs the cluster formation based on heterogeneity of PNs in a distributed way, forms clusters with a moderate number of nodes, limits the cluster radius to k-hops, decreases the change in the cluster composition, extends the average membership time in the clusters providing stability and generates less overhead traffic. Though it was aimed for PNs, this protocol can also be used for any other heterogeneous ad hoc network for clustering.

Wireless ad hoc networks will be an important component in future communication systems. The performance of wireless ad hoc networks can be improved by link quality-aware applications. Wireless link quality is dynamic in nature, especially in mobile scenarios. Therefore, accurate and fast packet delivery ratio estimation is a prerequisite to good performance in mobile, multi-hop and multi-rate wireless ad hoc networks. In this paper, we propose a novel packet delivery ratio estimation method that improves the accuracy and responsiveness of the packet delivery ratio estimation. The proposed link quality estimation components are implemented in a IEEE 802.11b/g test-bed. The experiment results show that the accuracy of the packet delivery ratio estimation can improve up to 50% in mobile scenarios without introducing overhead. We also show the end-to-end performance impact of this improved estimation on route selection using different routing metrics and configurations. The measurement results show that our packet delivery ratio method leads to better route selection in the form of increased end-to-end throughput compared to traditional methods, which respond slowly to the link dynamics.

The Mobile IP (MIP) protocol for IP version 4 as being standardized by the Internet community provides continuous Internet connectivity to mobile hosts, without requiring any changes to existing routers and higher-layer applications. We propose an alternative protocol, Mobile IP with Location Registers (MIP-LR) which is closer to the "service node" database approach used in the Public Switched Telephone Network (PSTN): before launching a packet to the mobile host, the sender first queries a database to obtain the recipient's current location. MIP-LR is designed for operation in enterprise environments or within logical administrative domains, as it requires a sending host to be aware which hosts are potentially mobile and implement the MIP-LR protocol. The benefits of MIP-LR are that potentially long routes, called "triangle routes", from the sender to the mobile host are avoided, encapsulation of packets sent to a mobile host is not required, the load on the home network as well as the home and foreign agents is reduced, and there is substantially improved interoperability with protocols such as RSVP for providing QoS guarantees. We carry out a simplified average-case analysis of the costs and benefits of MIP-LR and show it can result in significant reductions in mean network costs compared to MIP.

This paper provides insights on the status of broadband optical access market and technologies in Europe and on the expected trends for the next generation optical access networks. The final target for most operators, cities or any other player is of course FTTH (Fibre To The Home) deployment although we can expect intermediate steps with copper or wireless technologies. Among the two candidate architectures for FTTH, PON (Passive Optical Network) is by far the most attractive and cost effective solution. We also demonstrate that Ethernet based optical access network is very adequate to all-IP networks without any incidence on the level of quality of service. Finally, we provide feedback from a FTTH pilot network in Colmar (France) based on Gigabit Ethernet PON technology. The interest of this pilot lies on the level of functionality required for broadband optical access networks but also on the development of new home network configurations.

OPNET Modeler accelerates network R&D and improves product quality through high-fidelity modeling and scalable simulation. It provides a virtual environment for designing protocols and devices, and for testing and demonstrating designs in realistic scenarios prior to production. OPNET Modeler supports 802.15.4 standard and has been used to make a model of PAN. Iterations have been performed by changing the Power of the transmitter and the throughput will has been analyzed to arrive at optimal values.An energy-efficient wireless home network based on IEEE 802.15.4, a novel architecture has been proposed. In this architecture, all nodes are classified into stationary nodes and mobile nodes according to the functionality of each node. Mobile nodes are usually battery-powered, and therefore need lowpower operation. In order to improve power consumption of mobile nodes, effective handover sequence based on MAC broadcast and transmission power control based on LQ (link quality) are employed. Experimental results demonstrate that by using the proposed architecture, communication time and power consumption of mobile nodes can be reduced by 1.2 seconds and 42.8%, respectively. .

The results of initial reliability testing and some example applications of fingerprint authentication in CE appliances are given.

Group signature schemes existentially provide anonymity, non-repudiation and can make a mobile device untraceable. But using group signature only in designing anonymous key exchange system is time wasting and consumes much of other computing resources hence the use of it must be minimal especially when deployed on resources-constrained mobile devices. In .this paper, we propose the combined use of group signature because of its inherent security properties which are very important when a mobile user roams in the insecure wireless network and message authentication code to reduce the huge computational burden occasioned by group signature’s expensive public key operations resulting in unbearable authentication latency. In this paper, we built two authenticators, a signature based authenticator and a message authentication code based authenticator. These models are based on the Canetti-Krawczyk model. We implemented the design using Java 8 on Android Studio 2.2 and tested it on Genymo...

Wireless Mesh Networks (WMNs), a recently emerged type of access network offering wireless connectivity with the use of cheap and low transmission power devices. WMNs can also be applied to Spontaneous (Emergency/ Disaster) Networking with dynamically self-organized and self-configured communication infrastructures, with a high degree of cooperation between many individual wireless stations. In this paper, we propose a green approach for power management in WMN to improve energy efficiency and network utilization. We suggest energy-aware design and energy-aware routing protocol to study the performance of WMN over dynamic traffic profiles. The combination of this two Algorithms point that, with suitable design parameters (number of shutdown MRs and hop offset), we can efficiently reduce energy consumption in WMN without significantly impacting the network performance. Keywords-WMN; Energy Saving; Power Management; Routing; Sleep State.

Improving the computation efficiency is the key issue in image processing, especially in edge detection, because edge detection is very computationally intensive. With the development of real-time image processing application, fast processing response is becoming the major requirement in this area. In this paper, a parallel and distributed algorithm on Spiral Architecture for edge detection using a uni-directional MultiRing is proposed. The proposed algorithm is based on Master-Slave model. It guarantees a better load balancing among the processors (or nodes) and greatly reduces the traffic from and to the master node. It uses each MultiRing configuration more efficiently. It also improves the performance for message passing among the modes on the MultiRing.

The past decade has seen significant advancement in the field of consumer electronics. Various 'intelligent' appliances such as cellular phones, air-conditioners, home security devices, home theatres, etc. are set to realize the concept of a smart home. They have given rise to a Personal Area Network in home environment, where all these appliances can be interconnected and monitored using a single controller. Busy families and individuals with physical limitation represent an attractive market for home automation and networking. A wireless home network that does not incur additional costs of wiring would be desirable. Bluetooth technology, which has emerged in late 1990s, is an ideal solution for this purpose. This paper describes an application of Bluetooth technology in home automation and networking environment. It proposes a network, which contains a remote, mobile host controller and several client modules (home appliances). The client modules communicate with the host controller through Bluetooth devices.

2 Abstract: A Quos aware model for streaming multiple heterogeneous multimedia services over ubiquitous networks is presented whose aim is to simultaneously support as many service streams as possible and to optimally guarantee all users' Quos within these environments. This paper proposes a novel admission control algorithm, in conjunction with a quality adaptation scheme, which is capable of effectively guaranteeing and improving the service quality. Upon examination of the simulation results, we conclude that the proposed model and schemes provide valuable guidelines for the planning of future ubiquitous networks and multimedia systems.

It has a non-deterministic behaviour, due to the use of a probabilistic contention resolution algorithm, which impairs the support of real-time communications. In this paper, it is proposed the use of a modified algorithm for the collision resolution in shared Ethernet networks. Such algorithm, referred as high priority Binary Exponential Backoff (h-BEB), provides high priority traffic separation, enabling the support of real-time communications. It allows multiple Ethernet standard devices to coexist with one h-BEB modified station in the same network segment, imposing a higher priority for the transfer of h-BEB related traffic. The probabilistic analysis of traffic separation provided by the proposed algorithm shows that it guarantees an access delay significantly smaller for an h-BEB station, when compared with the access delay for BEB stations.

Cooperation of networked devices requires specification, advertisement and discovery of services that subsequently can be used either automatically or from a user interface. Middleware technologies support this in various ways. We implemented two technologies, viz., Universal Plug and Play and Corba and performed experiments with them. We compared them with respect to architecture, performance and generality.

Among the schemes, proposed in the literature to solve the route optimization problem in NEtwork MObility (NEMO), the prefix delegation-based schemes perform better than other schemes. Depending on the way the prefix are delegated, the prefix delegation-based schemes result in difference in performance under different speed at various distance from the home network (network to which mobile network usually belongs). Therefore, there is a need to evaluate the performance of individual prefix delegation-based scheme to find an appropriate scheme based on speed and distance from home network. In this paper, we identify the differences of the prefix delegation-based schemes using simulation. Results reveal that performance of the schemes depends on speed of the network and distance from home network.

This paper reports multi-user D-MIMO channel capacity calculations for 4x4 D-MIMO channels simulated using transmission loss and shadowing models derived from channel sounding measurements made with a vectornetwork-analyser (VNA) based channel sounding system. The channel sounding measurements were made with a bandwidth of 500 MHz at centre frequencies of 2.4 GHz, 18 GHz, and 28 GHz, in a small cluttered study room. Transmission was from an emulated sector antenna mounted with a downtilt of 62.5 degrees, above the suspended ceiling in the room at a height of 4 m above floor level. Reception was at 45 desk-top-height locations scattered throughout the room using an omni directional antenna at 2.4 GHz, and a step-wise azimuth and elevation scanning horn antenna with 10 deg. beamwidths in both planes at 18 GHz and 28 GHz. Reported results show that, since transmission loss differences and shadowing on the Tx-Rx links dominate over fast fading characteristics, given the same coverageare...

Unlike Mobile IPv4, where mobile node communicates with its peer through a longer path, via Home Agent, in Mobile IPv6 a mobile node directly communicates with its peers even though it moves to the new location and changes its IP address, this mechanism is called Route Optimization. In Route Optimization, the mobile node sends the binding message to its peer

In wireless roaming a mobile device obtains a service from some foreign network while being registered for the similar service at its own home network. However, recent proposals try to keep the service provider role behind the home network and let the foreign network create a tunnel connection through which all service requests of the mobile device are sent to and answered directly by the home network. Such Wireless Roaming via Tunnels (WRT) offers several (security) benefits but states also new security challenges on authentication and key establishment, as the goal is not only to protect the end-to-end communication between the tunnel peers but also the tunnel itself. In this paper we formally specify mutual authentication and key establishment goals for WRT and propose an efficient and provably secure protocol that can be used to secure such roaming session. Additionally, we describe some modular protocol extensions to address resistance against DoS attacks, anonymity of the mobile device and unlinkability of its roaming sessions, as well as the accounting claims of the foreign network in commercial scenarios.

Now that smart home appliances are easily plugged into smart home networks, the question of how to simplify security management, especially of access rights, for such appliances arises. The problem is aggravated by the fact that home users cannot be considered as "skilled" administrators, but are instead often technology-unaware users. Establishing trustworthiness when it comes to secure smart appliances has been considered as a "holy grail" not met by any current technology. The SECURE project aims to develop security mechanisms based on human notions of trust, which may prove part of the solution. Trust-based security mechanisms allow access rights to evolve among previously unknown principals, thus minimizing security configuration. This paper outlines the process of applying the SECURE project's security technology to smart home appliances with minimal user intervention.

Admission control algorithms have been widely researched for many years to guarantee the Quality of Service (QoS) for multimedia applications over the wired Internet. With the recent surge of wireless home networks, it is increasingly important to employ the admission control mechanisms in order to enhance the performance of the wireless multimedia applications. In this paper, we propose a framework for performing distributed admission control in a collaborative wireless environment. In particular, a wireless device will not inject a new flow into the wireless medium if it determines that by doing so, there is not enough resources to support all the existing flows. Our contributions are threefold. First, we propose a modification to 802.11x based network in order to increase the bandwidth efficiency. Specifically, doubling the contention window (CW) size after a collision is no longer necessary in the proposed wireless network. Second, we provide a performance analysis for the modified 802.11x based wireless networks with multiple flows having different throughput requirements. Third, using the theoretical analysis, we propose two distributed admission control algorithms based on the transmission opportunity (TXOP) and the CW. Simulation results confirm our theoretical predictions on the performance of the proposed admission control algorithms.

Replicating a data object improves the availability of the data, and can improve access latency by locating copies of the object near to their use. When accessing replicated objects across an internetwork, the time to access different replicas is non-uniform. Further, the probability that a particular replica is inaccessible is much higher in an internetwork than in a local-area network (LAN) because of partitions and the many intermediate hosts and networks that can fail. We report three replica-accessing algorithms which can be tuned to minimize either access latency or the number of messages sent. These algorithms assume only an unreliable datagram mechanism for communicating with replicas. Our work extends previous investigations into the performance of replication algorithms by assuming unreliable communication. We have investigated the performance of these algorithms by measuring the communication behavior of the Internet, and by building discrete-event simulations based on our measurements. We find that almost all message failures are either transient or due to long-term host failure, so that retrying messages a few times adds only a small amount to the overall message traffic while improving both access latency as long as the probability of message failure is small. Moreover, the algorithms which retry messages on failure provide significantly improved availability over those which do not.

Home devices like set-top boxes and media gateways are a rich source of users' information. They can play a role to facilitate interactions with friends and relatives in social networks. However these interactions have to follow policies to safeguard users' privacy while maintaining the complexity low for the average user. In this article we prototype an architecture based for home devices to participate in social networks. Besides, we explore the privacy issues and how the privacy offered in social networks can be improved. 1 .

In this article we present a system for sharing a Conditional Access Module among different visualization devices. Current pay-TV systems require having conditional access modules and smart cards replicated at every visualization device willing to access Pay-TV contents.

In this work we characterize the transmission capabilities of several one millimetre diameter plastic optical fibres (POFs) by analyzing their behaviour at a wavelength in the visible range using a bit error rate (BER) measurement system that allows data rate sweeping. We focus our investigation on transmission data rates in the gigabit range and in-home application distances. The data rate limit for each fibre length extracted from our measurements shows that large core plastic optical fibres are suitable candidates for home and office networks. Moreover, conventional step-index plastic optical fibres (SI-POFs) exhibit error free transmission of Gigabit Ethernet (GbE) data over 25 m, which is a reasonable length for in-home applications. However, only the tested graded-index plastic optical fibre (GI-POF) has been able to transmit GbE data at a 50-m length, which could be extended with a lower attenuation fibre.

Home network service has been integrated with various communication technologies to help people have a more convenient life. It is expected that wireless LAN (WLAN), B l u e t o o t h , u l t r a w i d e b a n d (U W B) , a n d Z i g b e e w i l l b e u s e d i n h o m e n e t w o r k s a s wireless access technologies to provide various home network services. WLAN study among them is actively making progress. But WLAN communication technologies have a problem in that access points (APs) cannot control the transmission range. This property allows the neighbor or person in the next house to receive the traffic and a malicious intruder to subvert the privacy. Therefore, authentication mechanisms have to be considered so that only an eligible user is authenticated to use the resources of a home network. IEEE 802.11 working group (WG) specifies an authentication procedure but it provide the only basic mechanism which can't protect the WLAN communications from the ineligible approach. The IEEE 802.11i standardization group is working on an access control based on IEEE 802.1x and air traffic encryption to strengthen WLAN security techniques. In a conventional method, the nonprofessional user finds it very difficult to setup security information inside WLAN stations and APs. However, there are the various user levels of computer knowledge in a home network. Because of this reason the way to setup authentication information should be prepared so it is easy for users who are not computer professionals. In this research, we propose access control mechanism considering the convenience of users, secure authentication protocol, and the intrusion detection system to support access control mechanism. Section II presents related literatures. In Section III, we propose authentication mechanism and the intrusion detection system for home network. The performance analysis of the proposed security mechanisms is presented in Section IV. Finally Section V concludes the research.
