Two-state discretized transmit power control for ad-hoc sensor networks

In this paper we analyze an Ad Hoc sensor network in which the transmit power of each sensor is limited to and randomly switched between two values. Specifically, we allow the sensors to be probabilistically in the OFF-state with zero transmit power or ON-state with maximum transmit power. The transmit probability is optimized in order to satisfy a certain quality of service. The analysis is based on a snapshot assumption and the solution is a centralized one which can be used as a benchmark for comparing the performance of distributed algorithms. The results show that a significant increase in supported Ad Hoc pairs and reduction of consumed power.
