Abstract

Mobile ad hoc networks (MANET) represent distributed systems that consist of wireless mobile nodes that can freely organize it into temporary ad hoc network topologies. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming dynamic topologies. If a node is used frequently for transmission or overhearing of data packets, more energy is consumed by that node and after certain amount of time the energy level may not be sufficient for data transmission resulting in link failure. MANET’s are generally battery-powered devices, the critical aspect is to reduce the energy consumption of nodes, so that the network lifetime can be extended. Since the network interface is a significant consumer of power, considerable research has been done to low-power design of the entire network protocol stack of wireless networks in an effort to enhance energy efficiency. This paper presents a review on the energy efficient routing protocols in Mobile Ad-Hoc Network (MANET).
