根据无线传感器网络(WSN)中数据转发与静电场中电荷移动的相似性,将sink节点和传感器节点的监测数据分别抽象成正、负电荷,无线传感器网络被抽象成由sink激发的虚拟静电场.以最大化网络生存时间为目标,以虚拟静电场中的静电引力作为路由选择标准,提出了多sink无线传感器网络路由算法.算法综合考虑传感器节点能耗的有效性和均衡性,以及sink的负载平衡,根据sink的邻居节点和传感器节点的剩余能量,为sink和传感器节点的数据分配相当电量的正、负电荷,依据电荷间的静电引力进行路由选择.理论分析与仿真实验结果表明:该路由算法具有较低的时间复杂性,能够有效的均衡节点的能量消耗,延长网络生存时间.
According to the similarities between the data transfer in wireless sensor network (WSN) and the charge transfer in electrostatic field, the monitoring data of sink node and sensor node are respectively abstracted into positive and negative charges, and the wireless sensor network is abstracted into virtual electrostatic field excited by sink. In order to maximize the network lifetime and take the electrostatic attraction in the virtual electrostatic field as the routing criterion, a multi-sink WSN routing algorithm is proposed.The algorithm considers the efficiency and balance of energy consumption of the sensor nodes and the load of the sink According to the residual energy of the neighbor nodes and sensor nodes in the sink, the positive and negative charges of the sink and the sensor nodes are distributed according to the static attraction of the charge. The theoretical analysis and simulation results show that the routing The algorithm has lower time complexity, which can effectively balance the node’s energy consumption and prolong the network lifetime.
