A Brief Review of Energy Efficient Protocols in Mobile Ad hoc Networks

Mobile Ad Hoc Networks (MANETs) is an assemblage of multi-hop wireless mobile nodes that communicate with each other without centralized control and established infrastructure. Energy efficient routing is not merely concerned about less power consumption, it also deals with increasing the time duration in which any network maintains certain performance level. Therefore, power management becomes an essential issue. Considering this, various authors have designed and developed different techniques to enhance the energy efficiency of mobile networks. This paper focuses on the comparative study of different developments and modifications that have been carried out in this field in past decades. It also highlights how these modifications have helped to enhance the network lifetime.
