Performance Analysis of Low Rate WPAN Topologies

Arpitha E M, Ramesh T M

Zigbee/IEEE 802.15.4 is a short-range wireless technology intended to provide applications with relaxed throughput and latency requirements in wireless personal area networks (PANs).It is designed to meet the needs for simple, low cost, low power and short range wireless networking. In this paper, we are analyse the performance of IEEE 802.15.4 topologies such as star, cluster tree, mesh of WPAN using different performance metrics like goodput ,throughput ,end-to-end delay with respect to routing protocol Ad hoc On demand Distance Vector(AODV)and Destination Sequenced Distance Vector(DSDV)usingNetworkSimulator2(NS2).Simulation results verify that DSDV gives better performance in star and cluster topologies and AODV gives better performance in mesh topology.
