摘要
由于节点的非均匀性,使得在非均匀部署下无线传感网络的能耗开销不一致,导致能量空洞.为了提高无线传感网络的生存周期,在非均匀部署下进行无线传感网络节点优化部署,实现能量空洞抵御,提出基于能量均衡控制的非均匀部署下无线传感网络能量空洞抵御模型.采用分簇能耗双阈值控制方法进行非均匀部署下无线传感网络的节点优化部署,提取目标网络节点传输的相干性特征值,结合模糊关联规则调度方法进行非均匀部署下无线传感网络的组网模型优化设计,以能量开销最小为约束代价,进行目标网络能量空洞的均衡控制,实现网络能量空洞抵御优化.仿真结果表明,采用该方法进行无线传感网络组网设计,能提高能量空洞的抵御能力,降低能量开销,提高了无线传感网络的寿命周期.
Due to the non-uniformity of nodes,the energy consumption of wireless sensor network is inconsistent under non - uniform deployment,resulting in the energy hole. In order to improve the life cycle of wireless sensor network,this paper presented a model to resist energy holes in wireless sensor network under non - uniform deployment based on energy balance control. The clustered energy consumption double threshold control method was used to optimize the node deployment of wireless sensor network under non - uniform deployment. Then,coherency feature values transmitted by the target network node were extracted. Through the fuzzy association rule scheduling method,the networking model of wireless sensor network under the non - uniform deployment was optimized and designed. Taking the minimum energy cost as the constraint cost,we achieved the equalization control of energy holes in target network. Finally,we optimized the network energy - hole resistance. Simulation results show that the proposed method can improve the ability of energy - hole resistance. Meanwhile,the energy overhead is reduced and the life cycle of wireless sensor network is lengthened.
