Energy optimization framework for WSN design

Published: 12 April 2010 Publication History

Abstract

In this paper we introduce an energy optimization framework for wireless sensor network (WSN) design. It deals with functional design, optimization and implementation of energy aware WSNs.
At the PHY layer, we provide a mechanism to optimize at design time and control at runtime the transmission power depending on the channel quality (distance, noise, fading). At the MAC layer, we use asynchronous scheduling to maximize sleep time, and we optimize the backoff time and the slot selection. At the NET layer, we optimize at design time, using closed form equations, and at runtime, using channel quality estimations, the number of nodes and hops to transmit packets across a given distance. We also discuss dynamic network routing approaches which reduce power with an acceptable error rate.
