Limited resources of nodes in MAMETs force the extensive studies for energy-aware multipath routing protocols, which should provide the fault tolerance for broken links and the load balance for extending bandwidth and equalizing energy consumption. This paper proposes a novel energy-aware multipath ad hoc routing protocol to equalize the energy consumption, thus, to extend the network lifetime of each node in MANETs. The proposed Time Delay On-demand Multipath (TIDOM) routing protocol accommodates the time delay function in flooding RREQ packets. The time delay function is inversely proportional to the residual battery capacity of intermediate nodes themselves. This function avoids nodes with poor residual battery capacity, and promotes nodes with good residual battery capacity joining the routes. Simulation results show that TIDOM improves the network lifetime, energy consumption, and additionally packet delivery ratio over the Ad hoc On-demand Multipath Distance Vector (AOMDV).
