传感器网络中基于非均匀分簇负载均衡路由算法黄 琛 房鼎益 陈晓江


□ 黄 琛 房鼎益 陈晓江

  摘 要:在非均匀分簇思想的基础上,提出了一种新的WSN多跳成簇路由算法。在该算法中,距汇聚点较近的节点直接与汇聚点通信,进一步减小了靠近汇聚点的簇规模,从而减轻了簇首负载,避免了不必要的能量消耗。仿真实验表明,该算法能使WSN网络负载更均衡,有助于解决能量空洞难题、延长WSN网络总的生存时间。

  Abstract:This paper proposed a novel load-balanced uneven cluster-based routing algorithm, named LUC, in which the node near the sink which was not the cluster head will communicate with sink directly, and the cluster near the sink was much smaller than that far from it. As a result, avoided unnecessary energy consumption and reduced the load of the cluster head near the sink. Simulation experiments demonstrate that the algorithm LUC can balance the energy-consuming, and provide an efficient solution to cope with the energy hole problem and prolong the entire WSN lifetime.

  Key words:wireless sensor networks(WSN); uneven clustering; energy hole; load-balanced
