In this paper, the energy consumption problem in Ad-Hoc networks has been discussed, and the existing power aware
routing algorithms and their classifications have been summarized. A performance comparison between DSR and
AODV protocols has been done using ns2 as a simulation tool. The simulation results revealed that DSR acts more
efficiently than AODV does under average conditions, and DSR is more convenient as a routing strategy with small size
networks. An energy consumption analysis of DSR protocol has been evaluated, results showed that, varying pause time
and traffic loads have a major effect on DSR performance, high traffic loads consume the network resources and
minimize its lifetime, the probability of initiating route discovery processes increases with the decreases of pause time,
and this also consumes the network resources and affect its lifetime. Based on these results a new power aware
multipath node disjoint routing scheme has been proposed. A new composite metric has been drawn as an effective way to distinguish between paths to select the two optimal ones. The Multipath node disjoint mechanism will be integrated
with the power and load aware metric to distribute the energy consumption among all network nodes in balanced
manner as a way to extend the operational life of the nodes and maximize the network lifetime. It is believed that this
routing scheme will overcome the drawbacks and the performance shortcomings of DSR protocol.
The next step is to implement this proposed routing scheme in ns2, and then evaluate its performance compared to
different power aware protocols.
