摘要: 为了提高无线传感器网络的生存时间,提出一种能量均衡的无线传感器网络节点路由算法。首先利用能量阈值和节点剩余能量将节点归类为2个区域,使得不同区域的节点当选为本轮簇头节点的概率不同,在数据稳定传输阶段,簇头与基站之间采用单跳与多跳相结合的通信方式,最后采用仿真实验测试算法的性能。结果表明,本算法有效提高了网络的能量利用率,能够实现节点之间的能耗均衡,使无线传感器的网络生存时间得到延长。

Abstract: In order to prolong the life of wireless sensor network, a novel clustering routing algorithm is proposed in wireless sensor networks based on energy equalization. Firstly, the new algorithm classifies nodes into two areas by using energy threshold and remaining energy of nodes, which makes nodes located in different areas have different probabilities of being elected as cluster head nodes. In the stage of data stable transmission, cluster heads and the base station use combined singlehop and multihop communication mode. Finally, the simulation experiment is used to test performance of the algorithm. The results show that the proposed algorithm can effectively improve the network energy efficiency and achieve energy consumption balanced among nodes, so it can prolong the life of wireless sensor network.
