A Survey on Power Aware Routing Protocols for Mobile Ad-Hoc Network

The Mobile Ad-Hoc network is a growing type of wireless network characterized by decentralized and dynamic topology. One of the main challenges in Mobile Ad-Hoc networks (MANETs) is that it has very limited power supply. To overcome the challenge, there are several power-aware routing protocols that have been developed in recent years. This paper describes a survey on some of those energy aware routing protocols for Mobile Ad-Hoc networks. The first category of power aware protocol schemes minimizes the total transmission power and the second category of schemes tries to increase the remaining battery level of every individual node to increase the lifetime of the entire network. The optimizations between these two objectives are important issues in power aware routing. This discussion focuses on different power saving algorithms and their development and modifications. After analyzing the existing works it has been seen that there are still several fields (using a dual threshold, passive energy saving etc) where we can give more focus in the future.
