Exchange power management for mobile ad hoc networks
J.G. Dorsey, Daniel P. Siewiorek · 2005
We present an incentive compatible mechanism for negotiated power management in mobile ad hoc networks. Using power measurements of real wireless interfaces, we show that a cost model for this environment must account for energy complementarity between overlapping traffic flows. We introduce the combinatorial exchange, a generalization of the route selection method already implemented in source routing networks, as a model which accounts for overlap. No previous mechanism for networks is incentive compatible in the power managing environment. We have developed a distributed procedure for exchange-based route selection, which we evaluate using realistic simulation. Our results show significant improvements in energy consumption variability, route setup latency, and application message delivery latency.
