摘要:

针对当前无线传感器网络覆盖算法存在能耗较高、节点大量冗余的缺陷,提出一种基于协同进化粒子群算法的WSN节能优化覆盖算法.以WSN的网络覆盖率、剩余能量和冗余程度为优化目标,建立粒子群优化模型.采用遗传算法的交叉变异算子,加强算法寻优能力.仿真结果表明,新的算法在提高能量利用效率的同时维护了良好的网络覆盖率,有效延长了网络生命周期,达到了节能优化覆盖的目标.

To solve the problem that the most covering algorithm of wireless sensor network has the weakness of serious energy consumption and lots of redundant nodes. We proposed an energy-conservation optimization covering algorithm which based on co-evolutionary particle swarm optimization（PSO）. We constructed the PSO model according to the ratio of the net- work coverage, residual energy and the degree of redundant. The mutation and crossover Operator of genetic algorithm was a- dopted to enhance the searching able of the proposed algorithm. The simulation results indicate that the proposed algorithm can improve energy efficiency, maintain a good network coverage rate, effectively prolong the lifetime of network and achieves the goal of energy-saving optimization covering.
