无线传感器网络节点负载的不均衡性,极易导致靠近数据汇聚中心的节点因过多的参与数据转发而提前死亡,从而在数据汇聚中心附近引起能量空洞,降低网络的生存时间.针对该问题,本文在综合考虑节点信息感知和信息传递的能耗基础上对圆形区域和带状区域的节点能耗进行了分析,并从理论上分别给出适用于这两种场景的节点非均匀分布方法.仿真结果表明,按该方法布设的网络在其生存周期结束时,内部各节点剩余能量基本相同.
The unbalanced load of nodes in WSN can easily lead to early death of nodes close to the data aggregation center due to excessive participation in data forwarding, which leads to the energy hole in the vicinity of the data aggregation center and reduces the network lifetime.In response to this problem, In this paper, the energy consumption of nodes in both circular and zonal regions is analyzed based on the energy consumption of node information perception and information transmission. In addition, the non-uniform distribution of nodes suitable for these two scenarios are theoretically proposed The simulation results show that the network deployed by this method has the same remaining energy at each node at the end of its life cycle.
