The Wireless Sensor Network (WSN) is spatially distributed autonomous sensor to sense special\ntask. WSN like ZigBee network forms simple interconnecting, low power, and low processing capability\nwireless devices. The ZigBee devices facilitate numerous applications such as pervasive\ncomputing, security monitoring and control. ZigBee end devices collect sensing data and send\nthem to ZigBee Coordinator. The Coordinator processes end device requests. The effect of a large\nnumber of random unsynchronized requests may degrade the overall network performance. An\neffective technique is particularly needed for synchronizing available node�s request processing to\ndesign a reliable ZigBee network. In this paper, region based priority mechanism is implemented\nto synchronize request with Tree Routing Method. Riverbed is used to simulate and analyze overall\nZigBee network performance. The results show that the performance of the overall priority\nbased ZigBee network model is better than without a priority based model. This research paves\nthe way for further designing and modeling a large scale ZigBee network.
