Opportunistic Relaying in Wireless Body Area Networks: Coexistence Performance
In this paper, a co-operative two-hop communication scheme, together with Opportunistic Relaying (OR), is applied within a mobile Wireless Body Area Network (WBAN). Its effectiveness in interference mitigation is investigated in a scenario where there are multiple closely-located networks. Due to a typical WBAN's nature, no coordination is used among different WBANs. A suitable Time-Division-Multiple-Access (TDMA) is adopted as both an intra-network and also an inter-network access scheme. Extensive on-body and off-body channel gain measurements are employed to gauge performance, which are overlaid to simulate a realistic WBAN working environment.
