A Framework for Configuration and Management Of Quality-Of-Service (Qos) in Wireless Zigbee Networks

摘要

The low cost, low power, low complexity Zigbee defined in IEEE standard 802.15.4 for low rate wpan's upon MAC and physical layer. The objective is to make possible of incalculable process among next generation devices with small transmitters and agree to communicate between devices with central PAN coordinator. Thus zigbee desires efficient routing ptotocol to deal with lowest amount of energy expenses and highest network life time. In this paper zigbee provides cross layer network protection and application service carried out with hierarchical cluster tree formation. Mac layer utilize the cluster tree formula to establish tree configuration subsequently that cluster table taken to the routing layer protocol of CLZBRP (Cross Layer Zigbee Based Routing Protocol). Here CLZBRP is compared with AODV (Ad Hoc On-demand Distance Vector Routing) and TBR (Tree-Based Routing) with QOS.
