摘要
分析了无线传感器网络的分簇路由算法,针对现有算法存在的热点问题,提出一种基于分簇思想的能量高效路由算法.采用簇首轮转及局部竞争优化节点簇内通信的能量消耗,采用粒子群优化算法均优化簇首节点的簇间通信负载和能量消耗,从而延长网络的生命期.仿真结果表明,该算法能够有效提高无线传感器网络生存期以及节点与网络的能量利用率.
In this paper, based on the analysis of some typical cluster - based routing algorithms, a novel cluster - based energy efficient routing algorithm is proposed to solve the hot spot problem reama- ing in current cluster- based routing algorithms. The rule of local competition and rotation of cluster head are performed in cluster formation to optimize energy consumption in intra - cluster communica- tion. Furthermore, particle swarm optimization is utilized to search optimal inter - cluster routing path for balancing energy consumption in inter - cluster communication, so that the network lifetime can be prolonged greatly. Simulation results prove that the proposed routing algorithm can improve energy effciency and network lifetime effectively.
