Energy and Throughput Tradeoff in Temporal Spectrum Sharing

It is envisaged that diverse types of short-range wireless systems coexist in shared spectrum in a near future. For low-power systems, throughput and energy efficiency are two design objectives that often conflict with each other. In this paper, the authors investigate the tradeoff between the throughput and the energy efficiency for a data-hungry but battery-driven low-power network which opportunistically shares radio spectrum in temporal domain. They provide a mathematical framework that determines the optimum frame lengths for the different objectives, and analyze the tradeoff.
