Various simulation studies for wireless body area networks (WBANs) based on the IEEE 802.15.6 standard have recently been carried out. However, most of these studies have applied a simplified model without using any major components specific to IEEE 802.15.6, such as connection-oriented link allocations, inter-WBAN interference mitigation, or a two-hop star topology extension. Thus, such deficiencies can lead to an inaccurate performance analysis. To solve these problems, in this study, we conducted a comprehensive review of the major components of the IEEE 802.15.6 standard and herein present modeling strategies for implementing IEEE 802.15.6 MAC on an NS-3 simulator. In addition, we configured realistic network scenarios for a performance evaluation in terms of throughput, average delay, and power consumption. The simulation results prove that our simulation system provides acceptable levels of performance for various types of medical applications, and can support the latest research topics regarding the dynamic resource allocation, inter-WBAN interference mitigation, and intra-WBAN routing.
最近已经针对基于 IEEE 802.15.6 标准的无线体域网 (WBAN) 进行了各种仿真研究。然而,这些研究大多应用了简化的模型,没有使用 IEEE 802.15.6 特有的主要组件,例如面向连接的链路分配、跨 WBAN 干扰缓解或两跳星型拓扑扩展。因此,这些缺陷可能导致性能分析不准确。为了解决这些问题,在本研究中,我们对 IEEE 802.15.6 标准的主要组件进行了全面回顾,并在此提出了在 NS-3 模拟器上实现 IEEE 802.15.6 MAC 的建模策略。此外,我们还针对吞吐量、平均延迟和功耗等方面的性能评估配置了现实的网络场景。仿真结果证明,我们的仿真系统为各种类型的医疗应用提供了可接受的性能水平,并能够支持最新的研究主题,如动态资源分配、跨 WBAN 干扰缓解和 WBAN 内路由。
