The problem of scheduling best effort flows from a dynamic population sharing a time varying wireless channel, with the objective of minimizing mean sojourn time is considered. The key tradeoff involved is between prioritizing flows with short residual sizes and maximizing opportunistic capacity gain by selecting flows that currently see good channels. This tradeoff is explicitly characterized by...
In this paper, we study several ways in which mobile terminals can backoff on their uplink transmit power in order to extend battery lifetimes. This is particularly effective when a wireless system is underloaded as the degradation in user's perceived quality of service can be negligible. The challenge, however, is developing a mechanism that achieves a good tradeoff among transmit power, idling/circuit...
