A wireless network of remotely located, self-powered video sensors must make efficient use of limited network capacity and power. An ideal media-access protocol for such network would fully utilize available throughput while using no more power than necessary and maintaining a reasonable level of fairness. To accomplish these goals, this paper proposes and evaluates a time-division multiple-access protocol that may run on top of unmodified 802.11 hardware. The paper compares and contrasts the protocol to other wireless power-saving mechanisms, then discusses the design and implementation of the protocol and its performance compared to standard 802.11 in terms of throughput, power, and fairness.
