Sensor nodes deployment is very critical in wireless sensor networks (WSNs) to cover a set of predetermined locations called “targets” in the region of interest (ROI), and to enhance the coverage area, optimal position of sensor nodes in ROI is essential. The aim of sensor nodes deployment and coverage in WSNs is to compute sensor node’s locations in the given network terrain such that they effectively detect the events as well as maximize the network lifetime. Battery depletion at sensor nodes creates coverage holes in ROI and it mitigates the network coverage. The objective of this paper is to define optimal locations of sensor nodes prior to their deployment and enhance the coverage area in the given geographical location using an improved particle swarm optimization (IPSO) algorithm. The experimental results showed superior coverage and faster convergence rate with the IPSO algorithm-than random deployments and grid-based deployments of sensor nodes.
