Power Optimization in Mobile Ad-Hoc Networks

A mobile ad hoc network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Mobile ad-hoc networks are the autonomous systems of mobile nodes forming network in the absence of any centralized support. This is a new form of network and might be able to provide services at places where it is not possible otherwise. Absence of fixed infrastructure poses several types of challenges for this type of networking. Almost devices in mobile Ad hoc network run on lithium-ion rechargeable batteries, these batteries have a lifetime of few hours of active lifetime. To solve this problem researcher tried to optimized power consumption in every aspect of mobile devices. Power consumption can be reduced at device level, at transmission level or may be by using optimized power aware routing protocol. In this paper we have given a brief description of basic aspects of mobile ad hoc network and studied various power saving techniques in mobile ad hoc network & given a comparative analysis of these techniques.
