Investigation Study on Energy Efficient Routing Techniques in Wireless Sensor Network

Wireless Sensor Networks (WSN) are infrastructure less network where sensor nodes are deployed with limited power, computational capacity and memory. WSN collects the information from sensed node. Routing in WSN is a demanding one for identifying the path to perform data transmission. Routing is a higher-level decision making that transmits the network packets from source to destination through intermediate sensor nodes. Researchers carried out their work on energy efficient routing techniques in WSN with help of clustering techniques. But, the packet delivery ratio was not improved and energy consumptionnot reduced. In order to address these problems, the existing routing techniques are reviewed in this paper.
