Mobile nodes have limited battery energy and in MANETs it is usually impossible to replace these batteries during emergency. So, energy efficient routing in MANETs is a very critical task. In this paper, a comparative performance analysis of routing protocols (DSR, STAR and LAR) has been done on the basis of energy consumption, packet delivery ratio, jitter and end to end delay using QualNet 5.0.2. The obtained results indicate that STAR is more energy efficient than other two protocols.
