Wireless sensor networks are used to monitor physical or environmental conditions like temperature, pressure, sound etc.Increasing the lifetime of wireless sensor networks is a major challenge because the nodes are equipped with low power battery.Energy efficient routing helps in increasing the lifetime of sensor nodes by maximizing the overall performance of the nodes.Generally in routing algorithm best path is chosen for transmission from source to destination,but if the same path is used for a long period of time for quick transmission time the nodes in the selected path will get drained fast.This paper discusses about the different methods used for increasing the lifetime of wireless sensor networks.
