【摘要】：针对无线传感器网络运行过程中出现的节点能耗不均及网络稳定周期较短的问题,提出一种改进的稳定选举协议。采用综合考虑节点剩余能量和能量消耗率的簇头选举机制,优化节点阈值计算方法,使剩余能量越多、能量消耗率越小的节点被选为簇头的概率越大,从而避免能量过低的节点承担较多网络负载,均衡节点间的能耗。仿真结果表明,改进协议能有效降低网络能耗,延长网络寿命。
[Abstract]:An improved stable election protocol is proposed to solve the problems of uneven energy consumption and short network stabilization period in the operation of wireless sensor networks (WSN). A cluster head selection mechanism considering the residual energy and energy consumption rate is adopted to optimize the node threshold calculation method. The higher the residual energy, the higher the probability that the node with lower energy consumption rate is selected as cluster head. In order to avoid too low energy node to bear more network load, balance the energy consumption between nodes. Simulation results show that the improved protocol can effectively reduce network energy consumption and prolong network life.
