| 摘 要： | 针对多级异构无线传感器网络(Wireless sensor networks, WSNs)路由问题,提出一种高效动态聚簇策略(Efficient and dynamic clustering scheme, EDCS). EDCS在给定多级异构网络环境下, 结合考虑理想状态的平均能量预测和历史能耗参考值估计下轮平均网 络剩余能量, 决定节点当选簇头的概率, 以此指导整个簇头选举过程. 同时在簇形成过程中引入类万有引力思想, 以引力 大小确定非簇头节点加盟哪个簇. 仿真实验结果验证EDCS的有效性, 且比LEACH, SEP, DEEC和EDFCM更适合应用 于多级异构无线传感器网络.

| Abstract: | In this paper, an efficient and dynamic clustering scheme (EDCS) is proposed for routing problem in heterogeneous wireless sensor networks. In order to guide the process of cluster head election for a given multi-level heterogeneous network, EDCS determines the probability of node to be a cluster head through average network residual energy estimation in next round by average energy consumption forecast in ideal state and reference value of historical energy consumption simultaneously. Furthermore, analogous universal gravitation is introduced to make non-cluster head node joining cluster in terms of gravitation during cluster formation process. Simulation results have proved efficiency of EDCS. It applies more suitable than LEACH, SEP, DEEC, and EDFCM for multi-level heterogeneous wireless sensor networks (WSNs). |
