This paper proposed a low-complexity medium access control (MAC) protocol tailored for body sensor networks (BSN) applications. The MAC protocol was designated to handle collision avoidance by reducing the numbers of the overhead packets for handshake control within the BSN. We also suggested a novel message recovery mechanism for getting back the lost physiological information. The adaptive synchronization scheme we have implemented exploited the features of multiple data-rate and adjustable precision design to support differentiated healthcare applications. The MAC protocol was fully implemented using our BSN development platform. The experimental results suggested the improved MAC design was compact and energy-efficient.
本文提出了一种专为人体传感器网络（BSN）应用量身定制的低复杂度介质访问控制（MAC）协议。该MAC协议旨在通过减少BSN内用于握手控制的开销数据包数量来处理冲突避免。我们还提出了一种新颖的消息恢复机制，用于找回丢失的生理信息。我们实现的自适应同步方案利用了多数据速率和可调精度设计的特点，以支持差异化的医疗保健应用。MAC协议使用我们的BSN开发平台完全实现。实验结果表明，改进后的MAC设计紧凑且节能。
