Energy Efficient Routing Protocols for Enhancing Network Lifetime of Wireless Sensor Networks

WSNs consists of small devices called sensor nodes having the capability of sensing the environment around them, computation the task, like gathering, storing, transmitting information, and performing wireless communications. Nowadays the main area of interest amongst researcher is the development of energy efficient algorithm in WSNs, so that the lifetime of sensors is enhanced. Since energy awareness is an essential design issue, many routing protocols have been proposed for WSN based on network structure and protocol operation. In this paper, I review only hierarchical-based routing protocol, like LEACH, PEGASIS, TEEN/APTEEN etc, and present a proposed algorithm for WSNs from the recent work and compare it with LEACH regarding lifetime of the network.
