Performance estimation and power minimizing scheme for a mobile ad hoc networking node

Abstract

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.
