Wireless body area networks (WBANs) have become a new paradigm for electronic healthcare applications; for instance, they are used to efficiently monitor patients in real-time. In this paper, an energy-efficient link scheduling (ELS) protocol for cognitive radio body area networks (CRBANs) is proposed, which aims to minimize energy consumption in CRBANs, while achieving higher probabilities of successful transmissions with multiple CRBANs. The proposed ELS transmits packets in the common control channel to control transmission links amongst CRBANs to the gateway and vice versa. The transmissions of CRBANs to the gateway are scheduled at a specific time by the gateway in different data channels, according to the traffic priority of CRBANs. Packet delivery ratio, delay, and energy consumption are evaluated for multiple CRBANs via extensive simulation.
无线体域网(WBANs)已经成为电子医疗应用的新范例;例如,它们被用于实时有效地监测患者。在本文中,提出了一种用于认知无线电体域网(CRBANs)的节能链路调度(ELS)协议,该协议旨在最小化 CRBANs 的能量消耗,同时提高多个 CRBANs 的成功传输概率。所提出的 ELS 通过公共控制信道发送数据包,以控制 CRBANs 到网关以及反之的传输链路。根据 CRBANs 的流量优先级,网关在不同的数据信道中为 CRBANs 到网关的传输安排特定的时间。通过广泛的仿真,对多个 CRBANs 的分组投递率、延迟和能量消耗进行了评估。
