Abstract—A wireless sensor network consists of many sensor nodes organised in a ad hoc manner to achieve a predefined goal. Although WSN’s have limitations in terms of memory and processors, the main constraint is battery problem which limits the lifetime of a network. In this paper describes using of controlled sink mobility sensor node to increase the lifetime of the sensor node with the support of triangulation localisation techniques in Wireless Sensor Network (WSN) the results show that our localisation algorithm are efficient in improving network life time and providing significantly better lifetime to fixed sink case and random movement strategy.
