Study on multi-channel reservation based MAC protocol for sensor networks
摘要
Abstract
Aiming at triple hidden terminal problems in wireless sensor networks, an adaptive duty cycle based multi-channel MAC protocol was proposed, called MCR. MCR efficiently handled triple hidden terminal problems with multiple channel reservation. By minimizing the lower bound of average times of channel switching in MCR, the optimal duty cycle in theoretical analysis was obtained. To investigate values of multiple channel reservation and dynamic duty cycling in MCR, extensive simulation and real testbed experiments were conducted. The results show that compared with other protocols, when the number of channels is larger or loads are heavy, M-cube improves throughput and energy efficiency significantly.关键词
