Since most ad hoc mobile devices today operate on batteries, energy-aware routings and power control techniques in wireless networks have drawn considerable research interests recently. This paper presents a reliable energy-aware routing algorithm (REARP) for unreliable ad hoc networks. The lifetime of the whole network and the energy cost for each packet are considered simultaneously in the routing processes of the REARP. Different from the formers, the energy cost of the link layer retransmission is also computed into the total energy consumption. Moreover, the REARP appropriately adjusts the transmission power by systematically integrating the reliability and power control techniques. We conducted extensive simulations to evaluate the performance of the new routing algorithms compared to a number of existing routing algorithms.
