SESAM: A semi-synchronous, energy savvy, application-aware MAC

Abstract

In spite of the huge recent research effort in the field, energy efficiency remains one of the key issues in wireless communications. The area most affected by energy inefficiency is Wireless Sensor Networks (WSN). In this paper we propose SESAM - a distributed MAC protocol, which, making use of application level information to predict future transmission instants between nodes, achieves an exceptional level of energy conservation.
