Impact Analysis on the Performance of Zigbee Protocol Under Various Mobility Models

Abstract

Wireless sensor network, IEEE 802.15.4/Zigbee is a specification for a suite of high level communication protocols that interconnects simple low power low processing capability wireless nodes for the transfer of data This paper aims at finding out the suitable mobility model that determines the effective positioning of nodes that gives the best throughput. In this study, the effect of four different mobility models, such as group, random walk, random waypoint and pursue mobility models has evaluated on various IEEE 802.15.4 based zigbee standard network. After the intensive simulations, it has been seen that by using the tree topology for the placement of nodes in the network and by configuring the movement of the nodes according to the group mobility model, network gives the maximum throughput and possess minimum data dropped in the network. So, it has concluded that under the given conditions, group mobility model outperforms other three mobility models.
