摘要
为了提高无线传感器网络的稳定期,提出了一种高效节能的加权选举协议。该协议使用集群策略结合链状路由算法,在异构的无线传感器网络环境下改善节能并且延长稳定期。仿真结果表明该协议在网络寿命和稳定期方面的性能都优于LEACH,SEP和HEARP。另外,实验表明在异构环境下稳定期依赖于节点的额外能量。
In order to improve the stability of wireless sensor network , a weighted election protocol is proposed in this paper .The protocol combines clustering strategy with chain routing algorithm to satisfy the energy conservation and stable period under heterogeneous environment in WSNs .Simulation results show that the protocol performs better than LEACH , SEP and HEARP in terms of network lifetime and stability period .It is also found that the longer stability period strongly depends on the higher values of extra energy during heterogeneous settings .
