Simulation and investigation of Zigbee sensor network with mobility support

The main purpose of this research work is to evaluate and analyze the behavior of Zigbee network topologies of wireless sensor networks. This paper investigates the impact of varying the number and speed of mobile nodes in Zigbee network using star, tree and mesh topologies. The functionality of star, tree and mesh topologies on the basis of packet delivery ratio, throughput and number of hops, media access control delay and end to end delay has been examined. The result show better performances of tree topology, which provides better packet delivery ratio and throughput. As the mobile nodes increases in tree topology the media access control delay and end to end delay decreases to lesser extent but there is no effect on number of hops it remain same.
