Recent advances in wireless networks have prompted much research attention in the area of Wireless Sensor Network (WSN). Sensor network consists of hundreds to thousands of low power multifunctioning sensor nodes operating in hostile environment with limited computational and sensing capabilities. In WSN it is critical to collect the information in an efficient manner. In order to avoid this problem the authors propose a new technique of improved AODV (Ad hoc On-demand Distance vector) routing using least cost path. It provides energy aware, data gathering routing structure in wireless sensor networks. It can avoid network congestion and fast consumption of energy of individual node. Then it can prolong the life cycle of the whole network.
