由于其广泛的应用范围和吸引人的特点，无线体域网络被认为是一项革命性的技术，它有望改变人们管理和考虑自己的健康和生活方式的方式。本文提出了一种自组织动态分簇(SDC)方法及其多址接入机制，以减少多个WBANs环境中的干扰，提高服务质量。据我们所知，这是第一篇专注于多个WBAN的频谱分配的论文。我们借用蜂窝网络中的小区和簇的概念来为不同的广域网络分配信道。通过WBAN间通信的信息交换，自组织分簇，提高WBAN内通信的数据传输率。此外，基于集群体系结构，还研究了一种适用于低隐私或高可靠性分组的WBAN间中继(IWR)协议。仿真结果表明，与现有框架相比，SDC具有更好的信干比。此外，SDC和IWR还在更高的数据分组递交率和更低的分组延迟方面提供了更好的服务质量性能。
Due to its wide application range and attractive features, wireless body area networks (WBANs) is considered as a revolutionary technology, which is envisaged to change how people manage and think about their health and their life styles. In this paper, we propose a self-organized dynamic clustering (SDC) method and its multiple access mechanism to mitigate the interference and improve the QoS in multiple WBANs environment. To the best of our knowledge, this is the first paper that focuses on the spectrum allocation for multiple WBANs. We borrow the concepts of cell and cluster from cellular networks to allocate the channels for different WBANs. The clustering is self-organized to improve the data transmission for intra-WBAN communication by the information exchange via inter-WBAN communication. Additionally, based on the cluster architecture, an inter-WBAN relaying (IWR) protocol for packets with low privacy or high reliability is also investigated. The simulation results show that SDC has better signal to interference ratio compared with existing framework. Besides, SDC and IWR also provide better QoS performance in terms of higher data packet delivery ratio and lower packet delay.
