In Wireless Sensor Network (WSN), though several works have been done on localization using mobile anchors, they cause huge delay in localization of the network since the mobile anchor has to cover the entire network. It will be difficult to provide maximum coverage to the entire network, without considering the visiting schedule of the mobile anchor node. In this paper, multiple mobile anchor based localization technique using Particle Swarm Optimization (PSO) is proposed. PSO is used to determine the trajectory of the mobile anchor nodes which is based upon the node density and the distance between the nodes in the network.
