Studying and improving energy efficient on demand routing protocols in MANET

Abstract

Ad hoc wireless network is comparatively a new paradigm in multihop wireless networking and has become popular It is an essential part of the computing environment consisting of infrastructure less mobile networks Since MANETs are infrastructure less self organizing rapidly deployable wireless networks they are highly suitable for applications that involve special outdoor events communications in regions with no wireless infrastructure emergencies and natural disasters military operations mine site operations urgent business meetings and robot data acquisition The nodes in the MANET are battery operated Failure of some node operation could greatly impede the routing performance of the network and even affect the basic availability of the network itself This thesis work proposes five different energy efficient routing protocols to increase the network life time by improving and managing the energy level in the nodes and by energy efficient routing discovery and maintenance procedures
