For wireless ad hoc networks with nodes having limited battery capacity, we propose route selection based on maximizing the minimum node battery power and minimizing the total transmission power required to reach the destination. The lifetime of the selected routes should also be long enough to sustain the data transmission, if possible. This motivates the design of a Location-Aided Power and Mobility Aware Routing (LAPMAR) protocol that can be used on an on-demand basis. This protocol uses location information and controlled flooding for improved system performance. This is studied using simulations and its performance is compared with other power aware protocols.
