Recent advances in wireless communication technologies have enabled the development of Wireless Sensor Networks (WSNs) that consist of low cost, power and small-size sensor nodes. ZigBee, an IEEE 802.15.4 based wireless sensor networks have been the promise of facilitating large-scale and real-time data processing in complex environments. Mobility management is a challenging task in the IEEE 802.15.4 based wireless sensor network. In this paper, comprises of recovery of the network in case of PAN coordinator failure using mobile node with trajectory. The simulation model consists of IEEE 802.15.4 based wireless sensor network which involves a mobile node deployed near PAN coordinator.
