Coverage reflects the perception Quality of Service, which is a basic problem in WirelessSensor Networks. With the development and applications of Wireless Multimedia SensorNetworks, in order to complete the task of target monitoring and information accessing, we mustensure that media sensor nodes can effectively coverage monitored or target area. Wirelessmultimedia sensor coverage control which is at the conditions of ensuring the quality of service,in order to achieve the maximization of network coverage, introduce coverage and intelligentoptimization algorithm to effectively control energy network nodes and enhance apperceive ofservice quality and prolong network survivability time.The study of this thesis is based directional sensing model,we proposed a sensor networkcoverage enhancement algorithms based particle swarm optimization, the algorithms aimed atperception of coverage, adjust direction for apperception and improve the network coverage;Second, the three-steps particle swarm optimization with the sensor networks coverageenhancement algorithm is proposed, it can effectively adjust the main apperception direction andposition by particle swarm search sensors, and reduce the overlap of the network and the blind;Finally, simulation results verify the proposed algorithm is feasible and effective. |
