In this paper, the authors establish the communication in short-range by using wireless technology and using Zigbee/IEEE 802.15.4 protocol. It is designed to meet the needs for low cost, low power, simple and short range wireless networking. In this paper, they analyze performance of IEEE 802.15.4 topologies are mesh, star, cluster tree of WPAN using different performance metrics like throughput, good put, end-to-end delay with respect to routing protocol Ad hoc On demand Distance Vector (AODV), Optimized Link State Routing protocol (OLSR), Dynamic Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), using Network Simulator2 (NS-2). Simulation results verify that DSR gives the better performance in mesh topology and DSDV gives better performance in cluster tree and star topology.
