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, the authors 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.
