To Improve the Network Lifetime Using Distributed Throughput Optimization for Zigbee Cluster Tree Networks

Zigbee is a low rate, less complex and low power consuming communication standard of IEEE802.15.14. Zigbee is used for connectivity of low rate WPAN, portable and mobile devices. Out of the different topologies Zigbee cluster-tree is most suitable for the LR-WPAN. This topology supports light weight routing and power saving operations. In this paper, the authors are addressing two major issues of a WSN that is maximum bandwidth utilization using the vertex constraint maximum flow approach and the second is the throughput optimization using the PPR Algorithm. The results of the simulation clearly show the improvement in the network lifetime due the proposed PPR algorithm over the existing approaches.
