Performance Analysis of Node Mobility in Beacon and Non-Beacon enabled IEEE 802.15.4 based Wireless Sensor Network

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. Work 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. The deployed mobile node routes through the coverage area of each PAN coordinator to recover the network. The work is also implicated with Beacon and Nonbeacon enabled IEEE 802.15.4 based wireless sensor network. The simulation model is done by using OPNET. Performances metrics like throughput and delay in the network are determined and analyzed.
