摘要
在以ZigBee路由协议为主的无线传感网络通信中,节点的能量消耗存在很强的随机性,无法提前预计各个节点的能量消耗情况,导致传统的协议中在节点能量消耗过大,路由效率低,网络时延长等问题,提出了一种结合AODVjr和簇树两种路由算法的改进ZigBee路由算法。在ZigBee基本路由算法的基础上,根据节点剩余能量的情况对路由节点进行分类,并简化了部分节点的算法流程,以传输数据的特点作为选择路由算法的依据。仿真结果表明,改进簇树算法具有更优越的性能。当节点数目相同时,改进簇树算法的时延会稍大,但在能量均衡方面有着较好的表现,达到了能量优化的目的,可以满足无线传感器网络的低成本、低功耗、高可靠性的要求。
In order to solve the problem that two main routing algorithms for energy consumption are too large, routing efficiency is low and network delay is too long, The paper proposed an improved cluster tree algorithm that combinates the routing algorithms of AODVjr with cluster tree. Based on the basic ZigBee routing algorithm, we clas- sifted the routing nodes according to the residual energy of the nodes, and simplified the algorithm process, and used the characteristics of data transmission as the basis of alternative routing algorithm. The simulation results show that the improved cluster tree algorithm has better performance. However, the delay of the improved cluster tree algorithm can be shghtly larger when the number of nodes are the same, and it has better performance in energy balance, a- chieves the purposes of energy optimization, meets the requirements of low cost, low energy consumption, high relia- bility of wireless sensor networks.
