碩士 === 國立臺灣科技大學 === 資訊工程系 === 97 === ZigBee is a protocol for Wireless Personal Area Network (WPAN) based on IEEE 802.15.4. The principles of ZigBee/IEEE 802.15.4 are low power consumption and low data rate. The routing protocols specified in the ZigBee Pro. Standard are Ad hoc On-Demand Distance Vector (AODV) routing and tree routing. However, AODV finds the route by broadcasting Route Request (RREQ) packets, and causes the flooding problems, which would consume more power and bandwidth. On the other hand, although tree routing has lower complexity and is easier to implement, it may generate longer routes. Therefore, it is important to design a routing protocol which follows the principles of low power and low data rate. In this thesis, we propose a new routing protocol for ZigBee called Address Assisted Routing in ZigBee (AARZ). AARZ takes advantages of Distributed Address Assignment Mechanism in ZigBee and changes ZigBee addresses into logical positions of tree. AARZ uses the logical position of tree and neighbor table to choose the next hop which is closest to the destination in the logical tree. The simulations show that AARZ outperforms tree routing for route length. AARZ also gets better performances than AODV and tree routing in terms of data throughput, packet loss, End-to-End delay of delivery and energy consumption.
