| 摘 要： | 在无线多媒体传感器网络(Wireless Multimedia Sensor Networks,WMSNs)中,由于节点部署的不合理,往往存在较多的监控盲区,影响了网络的服务质量。为了提高网络的覆盖率,在有向感知模型基础的基础上,提出了一种基于粒子群算法的WMSNs覆盖增强算法PSOCE。PSOCE算法以网络覆盖率为优化目标,以粒子群算法为计算工具,同时对节点的位置与主感知方向进行调整。仿真试验表明,PSOCE算法能够有效地改进WMSNs的覆盖质量,网络的覆盖率能提高6%～12%。

| Abstract: | In wireless multimedia sensor networks （WMSNs）, unreasonable deployment of nods may cause many blind areas, which affects the service quality of networks greatly. To improve network coverage, a particle swarm optimization （PSO） algorithm based coverage enhancing algorithm （PSOCE） is proposed. Based on directional sensing model, PSOCE used PSO to search rational locations and directions for all sensor nodes to optimize the network coverage. Simulation showed that PSOCE could improve coverage quality of WMSNs efficiently, and the coverage rate was increased by 6%-12%. |
