人体传感器网络（BSNs）对关键数据传输的可靠性提出了很高的要求。然而，由于体衰落效应和RF干扰，BSN通常容易受到信道损伤，这可能潜在地导致数据传输不可靠。本文提出了一种自适应、灵活的BSN容错通信方案，即AFTCS。AFTCS采用信道带宽预留策略，在信道发生损伤时提供可靠的数据传输。为了满足关键传感器的可靠性要求，采用容错优先级和队列自适应调整信道带宽分配。仿真结果表明，AFTCS可以减轻信道损伤的影响，同时产生较低的丢包率和延迟的关键传感器在运行时。
A high degree of reliability for critical data transmission is required in body sensor networks (BSNs). However, BSNs are usually vulnerable to channel impairments due to body fading effect and RF interference, which may potentially cause data transmission to be unreliable. In this paper, an adaptive and flexible fault-tolerant communication scheme for BSNs, namely AFTCS, is proposed. AFTCS adopts a channel bandwidth reservation strategy to provide reliable data transmission when channel impairments occur. In order to fulfill the reliability requirements of critical sensors, fault-tolerant priority and queue are employed to adaptively adjust the channel bandwidth allocation. Simulation results show that AFTCS can alleviate the effect of channel impairments, while yielding lower packet loss rate and latency for critical sensors at runtime.
