摘　　要：为提高无线多媒体传感器网络区域覆盖率,提出了人工鱼群优化的覆盖增强算法,算法基于三维方向传感器感知模型,优化网络传感器方向角度值,减少重叠覆盖以提升网络覆盖率。仿真实验表明该方法能有效增强网络覆盖率,并就传感器参数对覆盖率影响进行分析,分析结果表明优化后的网络覆盖率更加接近理想覆盖率。In order to enhance area coverage rate of wireless multimedia sensor network,a coverage enhancement algorithm based on artificial fish-swarm optimization is proposed.Based on 3D direction sensing model,the algorithm can optimize direction angle value of network sensor;and network coverage can be improved by decreasing coverage overlap.Simulations test indicates that this method can improve coverage rate effectively;impact of sensor parameters on coverage rate is analyzed,analysis result shows that coverage rate of optimized network is more approximate to the ideal coverage rate.
