无线传感器网络由许多电池能量有限的节点组成,该网络主要收集感知区域的信息.节点能量管理的优化对于延长网络寿命具有重要影响,如果每个节点直接向sink节点或基站发送信息,节点电池很快耗尽,网络也会失去作用.提出了动态路由的新方法以平衡节点能量开销,在Dijkstra最短路径算法和改进遗传算法的基础上,以功率有效性为首要原则,建立了网络拓扑.仿真结果接近最优解,达到节省能量的要求.
Wireless sensor network consists of many nodes with limited battery energy, and the network mainly collects the information of the sensing area.Optimization of node energy management has an important impact on extending the network lifetime. If each node sends information directly to the sink node or base station, the node battery is very The network is also lost. A new method of dynamic routing is proposed to balance the node energy cost. Based on the Dijkstra shortest path algorithm and the improved genetic algorithm, the network topology is established with the power efficiency as the first principle. The result is close to the optimal solution to meet the energy saving requirements.
