An Analysis Of Lifetime Improvement Techniques In Wireless Sensor Networks
N. Kayalvizhi, R. Prasanna · 2015
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 since the nodes are equipped with limited battery power and is not easy to replace or recharge the battery energy, when the nodes die. Energy efficient routing helps in increasing the lifetime of sensor nodes by maximizing the overall performance of the nodes. Usually best path is chosen for transmission of data packets from source to destination in routing algorithm, but if the same path is used for a long period of time for the fast transmission time the energy of nodes in the selected path will get drained fast. This paper discussed about different method used for increasing the lifetime of wireless sensor network.
