CRSN中基于能量收集的MAC协议
MAC protocol in energy harvesting CRSN
摘要
Abstract
Energy harvesting CRSN(EH-CRSN) is a new kind of WSN which introduced energy harvesting module to CRSN.By coordinating energy consumption and energy harvesting technology, sensor nodes adjusted themselves so that they greatly extended the life cycle and improved system performance.But the study of MAC protocol with energy harvesting modules added was still not so mature that this potential could not play out.For EH-CRSN MAC protocol issues, combined with energy harvesting technology, this paper designed an energy efficient strategy by adjusting nodes'' spectrum sensing participating rate, as well as adjusting the nodes'' duty cycle so that nodes achieved the effect of a balanced use of the collected energy.Meanwhile, this paper designed low-power energy management strategies for vulnerable nodes.Simulation results demonstrate that low-cost energy harvesting devices meet the need of nodes'' long-term operation with this scheme.关键词
