Sensor nodes deployment is critical for Wireless Sensor Networks (WSNs). Current methods are apt to enlarge the coverage by achieving a nearly even deployment with similar density in the wireless sensor network. Virtual Force (VF) directed Enhanced Particle Swarm Optimization (EPSO) algorithm, which uses a combined objective function to achieve the tradeoff of coverage and energy consumption. By assuming deployment as an optimization problem, EPSO is more reliable and flexible for WSNs than VF-style algorithms in terms of computation time, coverage, connectivity and efficient moving energy consumption. EPSO has good global searching ability and scalability, and it can quickly and efficiently get the sensor nodes deployment in WSNs.
