基于中继辅助的Intra-WBAN干扰抑制的动态信道接入方案
Dynamic Channel Access Scheme for Interference Mitigation in Relay-assisted Intra-WBANs
摘要：
这项工作解决了在一个单一的无线体域网（WBAN）的干扰缓解相关的问题。本文提出了一种分布式\textit{C}结合载波侦听多址接入与冲突避免（CSMA/CA）和\textit{F}灵活时分多址接入（\textit{T} DMA）的方案，用于中继辅助的WBAN内\textit{I}干扰\textit{M}的调度，即CFTIM。在CFTIM方案中，非干扰源（发射机）使用CSMA/CA与中继通信。同时，高干扰源和最好的中继使用灵活的TDMA通过使用稳定的信道与协调器（C）通信。所提出的方案的仿真结果相比，其他计划，因此CFTIM计划优于在所有情况下。这些结果证明，该方案减轻了干扰，延长了WBAN的能量寿命，提高了吞吐量。为了进一步降低干扰水平，我们分析表明，中断概率可以有效地降低到最小。
英文摘要：
This work addresses problems related to interference mitigation in a single wireless body area network (WBAN). In this paper, We propose a distributed \textit{C}ombined carrier sense multiple access with collision avoidance (CSMA/CA) with \textit{F}lexible time division multiple access (\textit{T}DMA) scheme for \textit{I}nterference \textit{M}itigation in relay-assisted intra-WBAN, namely, CFTIM. In CFTIM scheme, non interfering sources (transmitters) use CSMA/CA to communicate with relays. Whilst, high interfering sources and best relays use flexible TDMA to communicate with coordinator (C) through using stable channels. Simulation results of the proposed scheme are compared to other schemes and consequently CFTIM scheme outperforms in all cases. These results prove that the proposed scheme mitigates interference, extends WBAN energy lifetime and improves the throughput. To further reduce the interference level, we analytically show that the outage probability can be effectively reduced to the minimal.
