Implemented on Android and available as open-source, Oi! relies on social interaction, device-to-device short-range wireless transmission, as well as on history of contact duration to perform opportunistic data transmission. In this demo we show how Oi! can be used with intermittent Internet access between sources and destinations, to transmit data in a reliable and yet opportunistic way.

The millimeter wave (mmWave) frequency band is seen as a key enabler of multi-gigabit wireless access in future cellular networks. In order to overcome the propagation challenges, mmWave systems use a large number of antenna elements both at the base station and at the user equipment, which lead to high directivity gains, fully-directional communications, and possible noise-limited operations. The fundamental differences between mmWave networks and traditional ones challenge the classical design constraints, objectives, and available degrees of freedom. This paper addresses the implications that highly directional communication has on the design of an efficient medium access control (MAC) layer. The paper discusses key MAC layer issues, such as synchronization, random access, handover, channelization, interference management, scheduling, and association. The paper provides an integrated view on MAC layer issues for cellular networks, identifies new challenges and tradeoffs, and provides novel insights and solution approaches.

The use of the Internet is growing in this day and age, so another area has developed to use the Internet, called Internet of Things (IoT). It facilitates the machines and objects to communicate, compute and coordinate with each other. It is an enabler for the intelligence affixed to several essential features of the modern world, such as homes, hospitals, buildings, transports and cities. The security and privacy are some of the critical issues related to the wide application of IoT. Therefore, these issues prevent the wide adoption of the IoT. In this paper, we are presenting an overview about different layered architectures of IoT and attacks regarding security from the perspective of layers. In addition, a review of mechanisms that provide solutions to these issues is presented with their limitations. Furthermore, we have suggested a new secure layered architecture of IoT to overcome these issues.

The aim of the conference is to provide a platform to the researchers and practitioners from both academia as well as industry to meet and share cutting-edge development in the field.

Increased density of wireless devices, ever growing demands for extremely high data rate, and spectrum scarcity at microwave bands make the millimeter wave (mmWave) frequencies an important player in future wireless networks. However, mmWave communication systems exhibit severe attenuation, blockage, deafness, and may need microwave networks for coordination and fall-back support. To compensate for high attenuation, mmWave systems exploit highly directional operation, which in turn substantially reduces the interference footprint. The significant differences between mmWave networks and legacy communication technologies challenge the classical design approaches, especially at the medium access control (MAC) layer, which has received comparatively less attention than PHY and propagation issues in the literature so far. In this paper, the MAC layer design aspects of short range mmWave networks are discussed. In particular, we explain why current mmWave standards fail to fully exploit the potential advantages of short range mmWave technology, and argue for the necessity of new collision-aware hybrid resource allocation frameworks with on-demand control messages, the advantages
of a collision notification message, and the potential of multihop communication to provide reliable mmWave connections.

With so many people now wearing mobile devices with sensors (such as smartphones), utilizing the immense capabilities of these business mobility goods has become a prospective skill to significant behavioural and ecological sensors. A potential challenge for pervasive context assessment is opportunistic sensing, has been effectively used to a wide range of applications. The sensor cloud combines cloud technology with a wireless sensor, resulting in a scalable and cost-effective computing platform for real-time applications. Because the sensor's battery power is limited and the data centre’s servers consume a significant amount of energy to supply storage, a sensor cloud must be energy efficient. This study provides a Fog-based semantic for enabling these kinds of technologies quickly and successfully. The suggested structure is comprised of fundamental algorithms to help set up and coordinate the fog sensing jobs. It creates effective multihop routes for coordinating relevant devices and transporting acquired sensory data to fog sinks.

Berdasarkan perhitungan 1SM, didapatkan jarak optimal untuk penempatan AP tidak lebih dari 13 m pada propagasi LOS (rentang kuat sinyal-10dB sampai dengan-20dB, pada area koridor gedung) dan jarak 6 m pada propagasi NLOS (rentang kuat sinyal-40dB sampai dengan-50dB, pada area ruangan perkuliahan). Hasil analisis membuktikan bahwa keberadaan barrier mempengaruhi kekuatan sinyal yang diterima oleh user, sehingga penempatan perangkat WLAN, dalam hal ini AP perlu diperhatikan. ABSTRACT. This study aims to analyze the placement of access points (AP) in the STMIK Asia Malang. The first approach is done by site survey, with the aim of getting information about number and placement of APs that are currently applied to the STMIK Asia Malang. The results of this walktest will be used as a parameter for theoretical calculations using the One Slope Model (1SM) propagation model. Based on 1SM calculation, the optimal distance for AP placement is not more than 13 m in LOS propagation (signal strength range around-10dB to-20dB, in the corridor area of the building) and approximately 6m in NLOS propagation (signal strength range around-40dB up to-50dB, for the class area). The results prove that the existence of the barrier affects the signal strength that received by the user, so that the placement of WLAN devices, in this case, AP, needs to be considered. 1. PENDAHULUAN Penggunaan komunikasi nirkabel untuk tujuan pribadi dan komersial telah berkembang dengan begitu cepat pada beberapa dekade terakhir. Berbagai perangkat dikembangkan seiring dengan meningkatnya jumlah pengguna jaringan nirkabel, atau lebih dikenal dengan teknologi Wi-Fi (Wireless Fidelity). Teknologi Wi-Fi merupakan suatu teknologi yang menggunakan media transmisi udara (gelombang radio). Teknologi yang menggunakan standar IEEE 802.11a/b/g ini bekerja pada frekuensi 2.4GHz, yang saat ini telah tersebar di semua tempat, seperti kantor pemerintahan, perusahaan swasta, institusi pendidikan ataupun berbagai tempat hiburan (Zrno, Simunic, & Roboz, 2004). Salah satu teknologi Wi-Fi yang banyak digunakan pada institusi pendidikan adalah WLAN (Wireless LAN). WLAN merupakan jenis LAN yang dibangun dengan menggunakan teknologi komunikasi wireless yang menyediakan semua fitur yang diberikan oleh jaringan LAN berkabel (wired LAN). Jika dibandingkan dengan wired LAN, WLAN memiliki beberapa keunggulan di bidang mobilitas, fleksibilitas, kecepatan jaringan, biaya yang lebih rendah, manajemen yang lebih mudah, kapabilitas pengembangan yang lebih baik dan sebagainya (Meng, He, Deng, & Li, 2012). Kinerja suatu jaringan Wi-Fi dapat diketahui berdasarkan level sinyal yang dapat diterima oleh pengguna, sedangkan tingkat penerimaan sinyal bergantung kepada penempatan perangkatnya, dalam hal ini adalah access point (AP). Penempatan AP merupakan salah satu permasalahan di bidang infrastruktur jaringan, karena penempatan yang kurang tepat akan berimbas terhadap ketidakseimbangan area yang dapat di-cover. Penempatan access point yang tepat dapat memberikan coverage yang merata pada daerah yang diinginkan dengan seminimal mungkin overlap dan blank spot. Penempatan access point ini tentunya dengan memperhatikan adanya pathloss dan jumlah user yang akan dilayani sehingga dengan jumlah access point yang seminimal mungkin dapat diperoleh coverage yang maksimal (Puspitasari & Pulungan, 2015).

One of the major issues in Target-coverage problem of wireless sensor network is to increase the network
lifetime. This can be solved by selecting minimum working nodes that will cover all the targets. This
paper proposes a completely new method, in which minimum working node is selected by modified Ant
colony Algorithm. Experimental results show that the lever of algorithmic complication is depressed and
the searching time is reduced, and the proposed algorithm outperforms the other algorithm in terms.

This book chapter discusses the nature-inspired metaheuristic firefly algorithm (FA) applied in telecommunications. FA has been developed based on the behavior of the fireflies and the light emit, where the brightest firefly attracts the others into his direction. Besides, combining a stochastic behavior and a population-based multi-modal characteristic, FA approach is able to solve optimization problems in different areas of knowledge such as engineering, robotics, combinatorial optimization and so on. This chapter aims to show the FA performance in two distinct network optimization problems, namely: traffic characterization and energy-efficient cooperative networks. In the first problem, FA is applied as a clustering algorithm to create a network traffic pattern, called Digital Signature of Network Segment using Flow analysis (DSNSF), while on the second optimization problem, FA has been applied to the energy efficiency maximization problem in multi-carrier direct sequence code division multiple access (MC-DS/CDMA) cooperative networks.

With the expansion of information interchanges innovation, the interest for Higher Data Rate Services, for example, interactive media, voice, and information over both wired and remote connections is likewise expanded OFDM is transmission strategy created to take care of the expanding demand for higher information rates in interchanges, which can be utilized as a part of both wired and remote situations. New strategies to enhance data rates are required to exchange the broad measure of information which existing procedures can't bolster. These strategies must have the capacity to give high Data rate, bit error rate (BER), maximum delay. In this paper, We have presented a survey of QoS in OFDM wireless networks along with resource allocation and scheduling algorithms, its impact and how this modulation scheme can be utilised to enhance the performance of data transmission in the future of wireless networks.

Many of us think of the Internet as a global community. But two-thirds of the world’s population does not yet have Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters.
Project Loon balloons float in the stratosphere, twice as high as airplanes and the weather. They are carried around the Earth by winds and they can be steered by rising or descending to an altitude with winds moving in the desired direction. People connect to the balloon network using a special Internet antenna attached to their building. The signal bounces from balloon to balloon, then to the global Internet back on Earth.
Project Loon began in June 2013 with an experimental pilot in New Zealand. A small group of Project Loon pioneers tested the technology in Christchurch and Canterbury. The Project Loon pilot test began on the 40th parallel south. Thirty balloons, launched from New Zealand’s South Island beamed Internet to a small group of pilot testers. The experience of these pilot testers is now being used to refine the technology and shape the next phase of Project Loon.

In this paper we investigate the system level
performance of an Orthogonal Frequency Division Multiplexing (OFDM) Wireless LAN network enhanced through
Multiple-Input Multiple-Output (MIMO) techniques and
compare it to the performance of the conventional SingleInput Single-Output (SISO) network. The MIMO scheme
we apply is closed loop power allocation based on Singular
Value Decomposition (SVD). The above investigations are
carried out by means of a software based simulation platform. In order to characterize the system level performance
accurately, a suitable link-to-system interface based on
channel capacity has been developed. The performance
evaluation is achieved by monitoring the average system
throughput and the percentage of satisfied users. Extensive
system level simulations have been carried out that prove the superiority of MIMO techniques especially for heavy
traffic load conditions.

— Code Division Multiple Access (CDMA) uses spread spectrum technology where each user is assigned a code and allows multiple users to be multiplexed over the same physical channel. Whereas the time division multiple access (TDMA) divides access by time, while frequency-division multiple access (FDMA) divides it by frequency. CDMA is a form of "spread-spectrum" signaling, since the modulated coded signal has a much higher bandwidth than the data being communicated. Now, the Spread spectrum is used in the commercial applications such as, mobile handsets, internet, and satellite applications. By using Spread spectrum communication we can achieve the secure communication. In this paper the pure digital BPSK modulation technique is used to implement the CDMA Transceiver. The whole system is implemented only in the digital form, so cost is reduced. This design will makes whole system as a system on chip. All the modules functionality is verified with Modelsim simulation results. Xilinx ISE tools are used for FPGA synthesis. Spartan 3E development board is used for FPGA implementation.

 Abstract— Network is defined as a combination of two or more nodes which are connected with each other. It allows nodes to exchange data from each other along the data connections. Routing is a process of finding the path between source and destination upon request of data transmission. There are various routing algorithms which helps in determining the path and distance over the network traffic. For routing of nodes, we can use many routing protocols. Dijkstra's algorithm is one of the best shortest path search algorithms. Our focus and aim is to find the shortest path from source node to destination node. For finding the minimum path this algorithm uses the connection matrix and weight matrix Thus, a matrix consisting of paths from source node to each node is formed. We then choose a column of destination from path matrix formed and we get the shortest path. In a similar way, we choose a column from a mindis matrix for finding the minimum distance from source node to destination node. It has been applied in computer networking for routing of systems and in google maps to find the shortest possible path from one location to another location.

It is estimated that by 2020 there could be as many as 4 million visually impaired or blind people living in the UK. These visually impaired or blind people will use assistive technologies such as screen readers to access website content on the internet. Currently the governing body of the internet, the World Wide Web Consortium has released and continues to develop a new standard of the HTML markup language which is used to code website content. This new HTML standard, HTML 5 has been heralded as a new semantically correct markup language. HTML 5 should be more accessible to users of assisted technologies and should also facilitate the incorporation into websites of rich internet applications and other media in a more accessible way. However the Royal National Institute for Blind People (RNIB) have suggested that the opposite may be proving to be true and that HTML 5 websites may be more inaccessible than websites coded in earlier versions of HTML. This study employs a mixed methods methodology, including screen reader accessibility testing and web developer interviews. This methodology will establish the accessibility of HTML 5 coded websites and prove or disprove the hypothesis of the RNIB while adding granularity and perspective to the results of the testing.

Wireless Body Area Networks (WBANs) are rapidly evolving research field for patients' health monitoring and immediate medical response. In WBANs, tiny biosensor nodes deployed on body sense physiological data of patients and transmit it to Medical Server (MS) via Base Station (BS) for utilization by the Medical Officers (MOs). The security of human physiological data during dissemination in WBANs is of prime importance. In this paper we have proposed a light weight secure authentication and key agreement scheme which has three phases. In first phase we use encrypted í µí±›í µí±œí µí±›í µí±í µí±’ for secure node authentication and key agreement, a shortened form of hash " compressed hash (í µí° ¶ℎí µí±Ží µí± ℎ) " is used for the integrity of critical data packets. In second phase only critical data packets are transmitted instead of transmitting all sensed data. In third phase, updating round wise session keys maintain forward and backward secrecy. Patient Sensor Tracking (PST) feature of our scheme enhance physical security. Our solution is 43.75% efficient in communication cost and 28.27% in energy overhead as compare to other existing schemes, while satisfying all basic security parameters (authentication, confidentiality, integrity) and shields WBANs from the attacks of the adversaries with minimal communication overhead, computational cost, and energy overhead.

Fire is as destructive as it is useful. Without a proper pro-active approach to preventing fire
outbreaks, the results could be extremely disastrous when they occur. Thus, there is a need for a fast and
convenient way of reporting fire incidents. The growing usage of smartphones provides a way of equipping
the public with a means of reporting fire incidents to ensure prompt response and proper management of the
incidents. In this paper, we analyze the manual process of reporting fire outbreaks and design an automated
FEAP – a mobile application, to enable the public to quickly alert nearest fire emergency units of any
possible fire incidents. We developed FEAP with the aid of the Software Development Life Cycle (SDLC)
phases and Unified Modeling Language (UML) which was used as a model to visualize the design view of the
application. An Entity Relationship Diagram (ERD) was used for database design and a simple Graphical
User Interface (GUI) prototype of the proposed application was designed. Our work highlights a practical
application of analysis and design concepts in developing a software to providing an efficient solution in
reporting fire outbreaks.

Data mining is the use of automated data analysis techniques to uncover previously undetected relationships among data items. Mining frequent item sets is one of the most important concepts of data mining. Frequent item set mining has been ahighly concerned field of data mining for researcher for over two decades. It plays an essential role in many data mining tasks that try to find interesting itemsets from databases, such as association rules, correlations, sequences, classifiers and clusters . In this paper, we propose a new association rule mining algorithm called Rehashing Based Frequent Item set (RBFI) in which hashing technology is used to store the database in vertical data format. To avoid hash collision and secondary clustering problem in hashing, rehashing technique is utilized here. The advantages of this new hashing technique are easy to compute the hash function, fast access of data and efficiency. This algorithm provides facilities to avoid unnecessary scans to the database.

Close Circuit TV (CCTV) imaging plays a very important role in security and crime control. Continuous observation of the CCTV recording is a tedious job and an alternate solution is the automatic analysis of the scene. Automatic detection and recognition of human from CCTV images is playing important role in crime detection. The detection of different human poses (standing, sitting and lying) in CCTV images is the first step towards automatic scene analysis. In this paper, an algorithm is presented for estimating different human poses from CCTV images. The proposed algorithm works in two steps. In the first step the humans are extracted and in the next step the different poses are calculated using the ratio between the height and width of the human images. The proposed algorithm estimate human poses with 98% accuracy.
