Research Of Routing Protocols Based On ZigBee Wireless Sensor Network

ZigBee is a new kind of low-cost, low-power, short-range wireless communication technology, which designed for the Low-Rate Wireless Personal Area Networks (LR-WPAN). ZigBee network life is heavily dependent on the power of node, how to take full advantage of the limited energy of the nodes plays a crucial role in the ZigBee network to extend the network lifetime. The improvement of the ZigBee network routing protocol can significantly reduce energy consumption, so in this thesis, the improvement program of Cluster-Tree protocol and AODVjr protocol will be proposed by ZigBee technology.Firstly, this thesis introduces the basic features of the ZigBee technology, as well as the structure of the protocol stack, and study of the two routing protocols in the ZigBee network, such as ZigBee network topology, address assignment in the network layer, etc. In order to elaborate the features of AODVjr protocol and the advantages, disadvantages, situations of two basic routing protocols clearer, this thesis simulate the performance-related of AODV protocol and AODVjr protocol, Cluster-Tree protocol and AODVjr protocol separately. Secondly, in order to make up for the shortage of network routing protocols when using ZigBee technology, in this thesis, CTCR (Cluster-Tree based Crosscut Routing Protocol) is proposed to reduce the routing cost by using the neighbor table and crosscut program.The ACO-AOMDVjr protocol based on ant colony optimization and AOMDV the multi-path routing for AODVjr is proposed in this thesis. Finally, simulation results show that the two improved protocols effectively optimize the energy management of the network, greatly reduce the overall energy consumption of the network, they ensure the life of the ZigBee network and node.
