Online energy aware routing in wireless networks is the problem of finding energy efficient routes that maximize the network lifetime without the knowledge of future message flows. To maximize network lifetime, the paths for message flows are chosen in such a way that the total energy consumed along the path is minimized while avoiding energy depleted nodes. Finding paths which consume minimum energy and finding paths which do not use energy depleted nodes lead to conflicting objectives. In this paper, we compare energy aware routing strategies that known as Shortest Energy Path (SEP), Shortest Hops Path (SHP), max–min z (Max-Min), Shortest Widest Residual Path (SWRP), Shortest Fixed Width Path (SFWP) and Shortest Width Constrained Residual Path (SWCRP).
