The energy consumption of a WBAN system can be divided into three parts: transmitting, sensing and channel switching. Considering the fact that the WBAN system are power-supply limited, the energy-efficient spectrum handoff schemes have been proposed by many previous works, aiming at extending the endurance life of a WBAN system. In this paper, we consider a WBAN system which access multiple PU channels...
Designing low energy consumption, high efficiency media access control (MAC) protocols are one of the most important directions in wireless sensor networks (WSN). In this paper, we proposed a new contention reserve MAC protocol, named CRMAC, under the inspiration of IEEE 802.15.4's superframe structure. CRMAC is a MAC protocol suitable for intra-cluster WSN that combines the advantages of contention...
