Abstract

Aiming at the problem of low adaptability and low energy efficiency of MAC protocol of the wireless body area network, this paper proposed an adaptive MAC protocol based on IEEE 802.15.6 for WBAN(A-MAC). The protocol improved the superframe structure of IEEE 802.15.6, and adjusted the lengths of the contention phase and the non-contention access phase according to the proportion of nodes generating each priority data. It further divided the contention access phase into three sub-phases, and dynamically adjusted the length of the sub-phase according to the data priority. All nodes were competed for access channels in accordance with the channel access policy during the contention access phase. Finally, the simulation results show that the network performance using A-MAC protocol is significantly better than the network performance using IEEE 802.15.6 MAC and CA-MAC protocol in terms of throughput, power consumption and network delay.
