摘要 从考察中继协作技术对无线体域网能效性能影响出发,比较分析了典型的无线体域网用户间直接传输、单中继协作、多中继协作3种传输方式下的中断概率,以及基于中断概率约束的最小功率消耗问题。进一步分析启动和接收功率消耗、服务质量、中继位置等主要参数对系统能效的影响,从而实现无线体域网中不同用户按具体业务需求选择合适传输方式。 In this paper,we investigate the energy efficiency of relay cooperation in Wireless Body Area Network（WBAN）.The performances in terms of minimum power consumption with the constraint of targeted outage probability are analyzed and compared among three typical WBAN transmission schemes,i.e.,direct transmission,single-relay cooperation and multi-relay cooperation.Further,we analyze several parameters impacting on the system energy efficiency performance including the receiving and processing power consumption,the required quality-of-service,the relay location,in order to realize the tradeoff between the traffic needs of different WBAN users and the perfect transmission schemes.
