A Local Metric for Geographic Routing With Power Control in Wireless Networks
Overview This paper investigates the combination of distributed geographic routing with transmission power control for energy efficient delivery of information in multihop wireless networks. Using realistic models for wireless channel fading as well as radio modulation and encoding, The paper first shows that the optimal power control strategy over a given link should set the transmission power to achieve a special Signal-to-Noise Ratio (SNR) constant that can be computed using an elegant characteristic equation. Counter-intuitively, for typical radios, this corresponds to an optimal operating point of SNR that lies in the transitional region (where packet error rates are non-negligible).
