Enhancing the Target Coverage and Data Collection in Wireless Sensor Network

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Target coverage and data collection are the major problem in wireless sensor network. There are two types of nodes used to data collection process and target coverage. One is leaf node another one is parent node. Parent node used to collect the sensed data from leaf node. The leaf nodes used only perform the monitoring task. Extra work load create node failure. so parent node failure occurred. To proposed Particle swarm optimization method used to both target coverage and data collection using clustering method. Particle swarm optimization with simulated annealing used to data gathering process. Cluster formation and cluster head selection to avoid the more work load balancing and also present the distributed running time recovery of the cluster head failure.
