摘要

在本文中，我们考虑基于IEEE 802.15.4的无线身体区域网络(WBAN)，其中不同的生物医学传感器分布在人体上，并且必须将测量数据发送到协调节点。针对IEEE 802.15.4规范在信标启用模式下定义的带避撞算法(Slotted CSMA/CA)的开槽载波感测多址，我们提出了一种增强的后退策略，以提供节点对通信介质的公平访问。然后使用最新版本的Castalia Simulator对所考虑传感器的实际要求进行性能分析。所获得的结果表明，与传统规范的可靠性、及时性和吞吐量相比，我们的建议是有效的。

An enhanced backoff strategy for fair channel access in WBAN-based health monitoring systems

In this paper, we consider an IEEE 802.15.4-based Wireless Body Area Network (WBAN), where different biomedical sensors are distributed on a human body and have to send the measured data to a coordinator node. Focusing on the Slotted Carrier Sense Multiple Access with Collision Avoidance algorithm (Slotted CSMA/CA) defined by the IEEE 802.15.4 norm in the beacon-enabled mode, we propose an enhanced backoff strategy to provide nodes an equitable access to the communication medium. Then we analyze its performance over realistic requirements of the considered sensors using the latest version of Castalia Simulator. The obtained results reveal the efficiency of our proposal as compared to the traditional profile of the norm in terms of reliability, timeliness and throughput.
