Mobility Based Tree Construction for ZigBee Wireless Networks
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 1
Abstract
ZigBee is a specification for wireless personal area networks with low power, low cost, and a low data rate. It’s defined by IEEE 802.15.4 standard. In ZigBee wireless network, tree topology is commonly practiced to form wireless sensor networks and perform data delivery applications. In an environment splendidly connected with ZigBee devices, major topological changes can occur due to device failures, mobility and other factor. The reconstruction method designed to reduce the effect of topology changes. In this paper, we explain reduces the frequency route tree construction in mobility patterns and increase the data delivery ratio, and reduce the packet loss caused by node mobility of route tree construction. Overhearing mechanism also includes for mobile nodes to improve the data delivery ratio. We develop an efficient algorithm for mobility based tree construction. The effectiveness framework network topologies constructed using ZigBee is verified by NS2 simulation against a real world circumstances.
