Analysis of the scalability of hierarchical IEEE 802.15.4/Zigbee networks

چکیده
IEEE 802.15.4/Zigbee standard constitutes a promising technology for the deployment of low-power and low rate Wireless Personal Area Networks. Many practical applications of this type of networks may require the association of a nonnegligible number of nodes with strong power constraints. In that case, the most efficient way (especially in terms of battery consumption) of organising 802.15.4/Zigbee networks is by means of hierarchical cluster-trees. However, the standard does not impose any particular algorithm to organize, dimension or synchronize a cluster-tree network. This paper addresses this issue by proposing and comparing three simple strategies to parametrize the timing of superframes in static Zigbee clustertrees.

Performance Analysis and Improvement of Zigbee Routing Protocol
ZigBee is a recent wireless standard based on IEEE 802.15.4 for Personal Area Networks. Its use in Wireless Sensor Networks arouses many interests. In this paper, a performance analysis and an improvement of ZigBee routing protocol are carried out. ZigBee routing protocol uses a modified AODV by default and Hierarchical Tree Routing as last resort. Firstly, these two algorithms are compared in ...
متن کاملCross-layer network formation for energy-efficient IEEE 802.15.4/ZigBee Wireless Sensor Networks
In IEEE 802.15.4/ZigBee Wireless Sensor Networks (WSNs) a specific node (called the PAN coordinator or sink) controls the whole network. When the network operates in a multihop fashion, the position of the PAN coordinator has a significant impact on the performance: it strongly affects network energy consumption for both topology formation and data routing. The development of efficient self-man...
