Wireless Sensor Network Energy Consumption Optimization Based on the Genetic Algorithm

为了延长无线传感网络的使用寿命,提出了一种优化传感网络路由的遗传算法。该算法通过分析节点发送功率变化下的链路流量约束,链路最大传输效率约束,节点能耗约束等条件。感知路由从数据传输的能量消耗量出发,讨论最优能量消耗路径,提高节点能量利用率,延长网络生存期。其基本实现是根据节点的剩余能量和传输路径上的能量消耗来选择路由路径。仿真实验表明,该算法可以平衡节点能耗和邻节点使用数量,延长网络的生存寿命。

To prolong the service life of wireless sensor network,puts forward the optimization of sensor network routing of the genetic algorithm.The algorithm analysis nodes sending power change of flow balance constraint link,link maximum transmis sion efficiency constraint and node energy consumption constraint conditions,.Energy perception routing from data transmission based on the energy consumption,and discuss the optimal energy consumption path,efficient use of node energy,prolong the network life cycle.The basic realization is based on the rest of the node energy or transmission path energy needs to select rout ing path.Simulation experiments show that this algorithm can balance node energy and neighbor node quantity,prolong the net work life time.
