【摘要】：无线体域网是无线传感器网络在生物医疗等领域的一个重要的分支,是由植入人体体内或是可穿戴的分布在人体体表的各类传感器组成的无线网络,可用于监测、采集和管理人体的不同的生理参数(如血压、心率、血样浓度、体温等)和人体周围的环境参数(如湿度、光照强度、温度等)。无线体域网主要是在健康监护和远程医疗方面有广阔的应用前景,同时在日常的生活娱乐、体育运动、应急救灾、军事通讯和航空航天等方面也有着广泛的应用。无线体域网作为一种新兴技术,目前对其研究主要在网络结构、无线通信协议、无线通信技术、数据融合、情景感知以及无线体域网的节能等方面。本文主要是从无线体域网的节能策略方面展开研究,得到了基于网络编码和基于多中继协作方式的两种节能算法,主要的工作和创新点如下： (1)针对无线体域网中传输链路中断的情况,提出了一种基于网络编码的多中继协作算法,并分析该算法下系统的网络能耗,以及推导出系统的每比特网络能耗公式。通过仿真实验表明,该算法能较大程度地减少网络的整体能耗,并且得出在适当地增加信源节点或是减少中继节点的数目的情况下有助于降低网络的整体能耗。 (2)针对多源多中继无线体域网的系统模型,提出了一种基于多中继协作的中继节点能量比较算法,并且推导出该算法下的网络能耗公式。通过仿真实验表明,该算法同样可以较大程度地减少网络的整体能耗。另外分析比较了该算法和上述基于网络编码多中继协作算法在不同的信源节点和中继节点下每比特网络整体能耗情况,得出了两种算法的各自特点。
