Power consumption will be one of the most crucial issues to realize future communication environments. Mobile ad hoc networks have been the subject of active research for a number of years. They need no infrastructure and are low power consumption network alternative to existing infrastructure. On the other hand, unlike conventional processor platform, a data-driven multi-processor platform based on self-timed elastic pipeline is lower power architecture that establish parallel processing scheme without any runtime overhead. Thus, the power consumption of a data-driven processor is proportional to the throughput. This feature will be effective to predict and minimize power consumption by adjusting it to the demanded performance needed for a mobile ad hoc node. The research proposed in this paper is a first attempt to realize a system that consumes only substantially needed power by estimating the demanded performance and controlling the supplied power. This paper first proposes a method for estimating the demanded performance of a mobile ad hoc node. Then we try to estimate the suitable voltage and we present the data-driven power controlling scheme. We show that the performance estimation method combined with the power minimizing scheme can achieve minimum essential power consumption, 1/10 to 1/100 of the present.
