文章摘要
提出使用异构无线传感器网络提高网络稳定通信期的路由协议改进策略。该策略采用链状路由算法的分簇策略既延长了无线传感器在异构环境下的生存周期,也延长了传感器网络稳定期。仿真结果显示相对于分层路由协议LEACH(Low Energy Adaptive Clustering Hierarchy)和SEP(Stable Energy Protocol)来说,该改进策略在延长网络生存期及稳定期方面表现较好。同时,从仿真结果也可以看出较长的稳定期依赖于异构网络中高级节点的设置,部份传感器节点需要拥有更多的额外能量。
Abstract
This paper proposes a routing protocol improvement strategy which uses heterogeneous WSN to improve the stability period of networks. The clustering strategy of chain routing algorithm used by it prolongs the lifecycle of WSN in heterogeneous environment, and also extends the stability period of the sensor network. Simulation results show that the new strategy performs better than LEACH (low energy adaptive clustering hierarchy) and SEP (stable energy protocol) in terms of prolonging the lifetime and stability period of the network. Meanwhile, the simulation result also tells that the longer stability period depends on the setting of higher nodes in heterogeneous networks, part of the sensor nodes requires more extra energy.
