摘　　要：在无线个域网中,利用多终端进行协同传输可以很好地改善系统的吞吐量,提高传输速率。针对无线个域网协同传输中的终端选择问题,提出了一种基于模糊层析分析法的多属性决策算法。该算法使用终端接入点的信号接收强度、可用带宽和时延等多种属性计算终端性能,能够选择性能较好的多个终端进行协同传输。仿真表明,该算法能够选择出合理的、性能较优的终端进行协同传输,有效地提高了系统的吞吐量。By multi-terminal cooperative transmission,greater throughput and higher transmission rate can be achieved in wireless personal area network（WPAN）.To solve the terminal selection problem in the cooperative transmission of WPAN,the paper proposes a multi-attribute decision making algorithm based on fuzzy analytical hierarchy process（AHP）.The algorithm selects the terminals with better properties,including received signal strength,available bandwidth and access delay.The simulation results indicate that the chosen terminals are appropriate for cooperative transmission,and finally the system throughput is increased.
