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.
