Abstract: Mobile ad hoc networks are wireless networks with no fixed infrastructure. It contains mobile nodes that maintain network connectivity through wireless communications. Due to lack of central infrastructure they can be easily deployed in situation of crisis or as per need. However, nodes in MANETs are powered by limited supply of battery energy. Therefore, efficient energy conservation becomes of prime importance for the overall functioning of an ad hoc network. Many energy aware routing protocols have been developed which aim at achieving energy efficiency via routing procedures. Various mechanisms have been developed that maximise the lifetime of nodes and in overall the network lifetime. In this paper, we study recent mechanisms and protocols proposed which provide energy conservation in mobile ad hoc networks.
Keywords: mobile ad hoc networks; MANETs; energy efficiency; energy conservation; energy aware routing protocols; battery power; transmission power; network lifetime.
