Wireless Body Area Networks (WBANs) constitute an emerging technology in the field of health care that makes health monitoring possible from one’s home itself. WBANs open many challenges by placing sensors on/inside human bodies for collecting various health-related information. Unlike traditional Wireless Sensor Networks (WSNs), communication in WBANs suffers from high channel fading and attenuation due to human body fat. Therefore, relay-based communication with data forwarding techniques is used to handle link failures and poor network connectivity. Accordingly, in this survey article, we present a comprehensive study of relay-based communication mechanisms in WBANs. We begin with a brief look at the multi-tiered architecture of WBANs, how direct communication works, and how relay-based communication is different. Subsequently, we present a detailed review of relay node selection approaches, which, in turn, also affects how a WBAN performs. In this context, we also look at the unique quality of service (QoS) demands of WBANs and how they can be assured.

WBAN 中基于中继的通信

无线体域网 (WBAN) 构成了医疗保健领域的一项新兴技术,可以在家中进行健康监测。WBAN 通过在人体上/体内放置传感器来收集各种与健康相关的信息,带来了许多挑战。与传统的无线传感器网络 (WSN) 不同,WBAN 中的通信会因人体脂肪而遭受高信道衰落和衰减。因此,基于中继的通信与数据转发技术用于处理链路故障和网络连接性差。因此,在这篇调查文章中,我们对 WBAN 中基于中继的通信机制进行了全面研究。我们首先简要介绍 WBAN 的多层架构、直接通信的工作原理以及基于中继的通信有何不同。随后,我们对中继节点选择方法进行了详细回顾,这反过来也会影响 WBAN 的执行方式。在这种情况下,我们还研究了 WBAN 的独特服务质量 (QoS) 需求以及如何保证这些需求。
