Zigbee Based Reconfigurable Clustered Home Area Network

The zigbee communication is a communication technology to connect local wireless nodes and provides high stability and transfer rate due to data communication with low power. In the nodes away from coordinator in one PAN, the signal strength is weak causing the network a shortage of low performance and inefficient use of resources due to transferring delay and increasing delay time and thus cannot conduct seamless communication. This study suggests the grouping method, that makes it possible to perform wide range data transferring depending on the node signal strength in zigbee node and analyzes the suggested algorithm through simulation. Based on IEEE 802.15.4 Low Rate-Wireless Personal Area Network (LR-WPAN) standard, the Zigbee standard has been proposed to interconnect simple, low rate and battery powered wireless devices. The de-ployment of Zigbee networks is expected to facilitate numerous applications such as Homeappliance net-works, home healthcare, medical monitoring and environmental sensors. An effective routing scheme is more important for Zigbee mesh networks. In order to achieve effective routing in Zigbee Mesh networks, a Zigbee protocol module is realized using NS-2. The suitable routing for different data services in the Zigbee application layer and a best routing strategy for Zigbee mesh network are proposed. The ZigBee standard provides network, security, and application support services operating on top of the IEEE 802.15.4 Medium Access Control (MAC) and Physical Layer wireless standard. It employs a group of technologies to enable scalable, self-organizing, self-healing networks that can manage various data traffic patterns. ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost allows the technologyto be widely deployed in wireless control and monitoring applications, the low power-usage allows longerlife with smaller batteries, and the mesh networking which promises high reliability and larger range. ZigBee has-been developed to meet the growing demand for capable wireless networking between numerous low power devices. The aims of this network are to reduce the energy consumption and latency by enhancing routing algorithm. In a traditional tree routing when a node wants to transmit a packet to the destination, the packet has to follow child/parent relationship and go along tree topology, even if the destination is lying at nearby source. In order to solve this problem, an Enhanced Tree Routing Algorithm is introduced using ZigBee network. This algorithm can find the shortest path by computing the routing cost for all of router that stored in neighbor table, and transmit the packet to the neighbor router that can reduce the hop count of transmission. The enhanced tree routing algorithm can achieve more stable and better efficiency then the previous traditional tree routing algorithm.

IEEE 802.15.4 proposes a cluster-tree topology to organize a network and to support energy efficient data routing. In this paper, we propose a new approach to manage mobility by adapting this topology. Our approach is based on the link quality indicator (LQI) metric. It aims at anticipating the loss of the association between coordinators and mobile nodes. Hierarchical addresses are attributed to coordinators regarding their position in the network. Then, a speculative algorithm is proposed to choose the next coordinator of association. In this paper, we focus on the consumed energy average and the changing coordinator procedure delay average of moving nodes in the network.

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. .

——Zigbee is a distinctive communication criterions principally aimed to be deployed for wireless personal area networks with low rate. It's an IEEE 802.15.4 based usual incurring minimal amount of complexity, cut rate and low strength consumption. Zigbee cluster-tree be good-recognized zigbee topologies especially suitable for WSN's consuming low strength and sustaining cut rate since it supports power rescue operations. When Zigbee cluster network generates more traffic, the performance of the network tends to decline due to lack of bandwidth utilization. The earlier techniques employed for the purpose was providing supple routing and increased bandwidth utilization. But they tend to compromise on an ideally and convergence rage of bandwidth usages. Thereby we propose as Enhanced Distributed Adoptive Parent (EDAP) based structure for Zigbee cluster tree networks that manages changing traffic weight communication at any granted moment. The nodes collecting the sensed data are appropriated depending on the traffic load demands. Such a framework when applied improves bandwidth of the network and in turn improves the overall performance of the network.

When designing a wireless sensor network based on ZigBee, it is very important to choose the right network topology, especially in networks with many nodes such as residential areas. Choosing the wrong topology will have an impact on the performance of the wireless sensor network as a whole because it will cause a large delay value. To overcome this, in this study a ZigBee-based wireless sensor network simulation was carried out using an environmental model consisting of several residential units, with one ZigBee device for each house. In addition, three ZigBee network topologies namely mesh, star, and tree are used in this simulation. This is done to determine which topology model will work best in a residential environment. The housing used for the simulation in this study is Citraland Waterfront City Housing which is located in Palu City, Central Sulawesi Province, Indonesia. By using simulations in the Opnet Modeler 14.5 application, it is known that the star topology on the Zig...

WSNs are becoming an important topic in the research arena. Their low cost and the wide range of applications where wireless sensor networks can be applied, make them an important research and commercial field in the short term. Furthermore, the IEEE 802.15.4 standard for physical and MAC layer in addition with the Zigbee specification for the network and application layer, are an enforcement for WSNs. Much research in WSNs related topics such as energy-aware, MAC protocols, routing protocols, security, location, etc is being carried out nowadays. An open issue is the interconnection between wireless sensor networks where different approaches can be adopted: bridging (extension devices) and proxying (mainly middleware entities). This paper is focused in the bridging approach for Zigbee networks. Our objective is to establish a Zigbee Extension Device Network for the case where the different clusters can not be connected to the same Zigbee network by using the multihop routing protocol defined in Zigbee. A Zigbee cluster is a set of Zigbee nodes. This paper introduces three different solutions to join the disconnected clusters of the Zigbee Network: a central approach (based on the use of a central station) and two distributed approaches; one of them proposes that each Zigbee Extension Device stores the information of all the other Extension Devices within the network while the other uses a P2P Zigbee Extension Device Overlay Network to join the disconnected Zigbee Clusters. The paper includes the analysis of each solution and the comparison among them.

Wireless sensor networks are power constrained since nodes operate with limited battery energy. In order to maximize the lifetime of sensors networks, traffic should be sent via a route and different traffic applications that can be avoid nodes with low energy. In this paper, we analyze the performance of Zigbee home automation network under different traffic applications (such as constant bit rate (CBR), variable bit rate (VBR), and file transfer protocol (FTP)) by considering energy consumption parameter. The simulation results represent the impact on power consumption due to these different traffic applications in transmit mode, receive mode and idle mode. Energy consumed in transmits, receive and idle mode, for FTP application is low as compare to VBR and CBR. In terms of energy consumption FTP overall performs better than other traffic application since low power consumption corresponds to high efficiency.

ZigBee, a unique communication standard designed for low-rate wireless personal area networks, has extremely low complexity, cost, and power consumption for wireless connectivity in inexpensive, portable, and mobile devices. Among the well-known ZigBee topologies, ZigBee cluster-tree is especially suitable for lowpower and low-cost wireless sensor networks because it supports power saving operations and light-weight routing. In a constructed wireless sensor network, the information about some area of interest may require further investigation such that more traffic will be generated. However, the restricted routing of a ZigBee clustertree network may not be able to provide sufficient bandwidth for the increased traffic load, so the additional information may not be delivered successfully. In this paper, we present an adoptive-parentbased framework for a ZigBee cluster-tree network to increase bandwidth utilization without generating any extra message exchange. To optimize the throughput in the framework, we model the process as a vertex-constraint maximum flow problem, and develop a distributed algorithm that is fully compatible with the ZigBee standard. The optimality and convergence property of the algorithm are proved theoretically. Finally, the results of simulation experiments demonstrate the significant performance improvement achieved by the proposed framework and algorithm over existing approaches.
