摘　　要：针对无线传感器网络中的能量空洞问题,建立了包含节点感知能耗、处理能耗、接收能耗、发送能耗的能量空洞问题分析模型,提出能量消耗速率的概念,并且给出了避免能量空洞问题的条件。利用该分析模型从理论上分析了节点密度、数据采集率、数据融合以及路由方式等策略对缓解能量空洞问题的有效性。最后,通过仿真实验数据与理论分析的对比验证了该模型对能量空洞问题分析的正确性,并且给出了缓解能量空洞问题的最佳策略。Aiming at the energy hole problem in wireless sensor networks,a model considering energy of sensing,processing,transmitting,and receiving was established to analyze the energy hole problem.The concept of energy consuming rate was proposed,and the qualification for avoiding energy hole problem was provided.Using this model the effectiveness of some existing approaches towards mitigating the energy hole problem was investigated,such as node density,source bit rate,data fusion and routing style.The simulation results were given and compared with theoretical analysis to validate the correctness of this model,and the best way to mitigate the energy hole problem was suggested.
