无线传感器网络能量均衡的多sink分簇路由算法

针对无线传感器网络中传感器节点能量有限以及节点能耗不均衡的问题，提出了一种基于能量均衡的多sink分簇路由算法（EBMCR）。该算法在簇头选择阶段，综合考虑了节点的剩余能量级和节点到sink的距离等因素选择簇头节点；在簇间通信过程，采用多跳传输的方式，综合考虑了路径能量消耗、路径最小剩余能量和节点到sink的跳数等因素，选择节点到多个sink的最优路径。仿真结果表明，该算法能够有效地均衡网络能量，延长网络生命周期。

Energy balanced multi-sink clustering routing algorithm for wireless sensor network

With the limited energy of sensor nodes and the unbalanced consumption of nodes’ energy in Wireless Sensor Network（WSN）, this paper proposes an Energy Balanced Multi-sink Clustering Routing algorithm（EBMCR）. In the cluster head selection phase, the EBMCR algorithm considers the residual energy level of sensor nodes and the distance between sensor nodes and sink nodes to select the cluster head. In the inter-cluster communication process, the EBMCR algorithm adopts multi-hop transmission mode, calculating the energy consumption of the path, the minimum residual energy of the path and the hops from the sensor node to the sink node, to select the optimal path to the best sink nodes. Simulation results show that the EBMCR algorithm can balance the network energy effectively and prolong the network life.
