基于ZigBee网络的路由算法研究

Research of Routing Algorithm Based on ZigBee Network

ZigBee网络的传统算法(簇树路由算法和AODVjr路由算法)在发现路由过程中节点能耗较大。为此,结合节点能量、簇树路由算法和AODVjr路由算法,提出一种改进的ZigBee网络路由算法。该路由算法选择路由时尽量避免能量较低的节点,选择最佳路径,维持网络稳定性。仿真结果表明,改进后的算法能有效降低整个网络总体能耗,合理分配网络负载,大大降低了死亡节点数量,从而延长整个网络的使用寿命。

In view of the traditional algorithm of ZigBee network,the cluster tree routing alg-orithm and AODVjr routing algorithm in the routing discovery process,the node＇s energycon-sumpti-on is relatively large.To this end,an improved ZigBee network routing algorithm ispr-oposed by combining the node energy and the cluster tree routing algorithm and the AODVjr routing algorithm.The routing algorithm chooses the route to avoid the lower energy of the node.And select the best path,maintain network stability.Simulation results show that the improved algorithm can effectively reduce the overall energy consumption of the entire net-work,capable of rational allocation of network load equilibrium,to a large extent reduce the number of dead nodes,and prolong the service life of the entire network.
