Energy Efficiency of Adaptive-Rate Medium Access Control Protocols for Sensor Networks
Energy efficient protocol design is the aim of current researches in the area of sensor networks where limited power resources impose energy conservation considerations. In this paper the authors care for Medium Access Control (MAC) protocols and after an extensive literature review, two adaptive schemes are discussed. Of them, adaptive-rate MACs which were introduced for throughput enhancement show the potency to save energy, even more than adaptive-power schemes. Then they propose an allocation algorithm for getting accurate and reliable results. Through a simulation study they validated the claim and showed the power saving of adaptive-rate protocols.
