摘　　要：在无线频谱系统的管理中,中继点接入是信息传输非常重要的1个环节,但传统的局部中继节点介入方式存在性能协调不均衡的问题,无法兼顾能量节约和传输效率,甚至会出现中继节点碰撞问题,对此提出局部阈值中继信息博弈协调策略DTR协议,来对无线频谱系统中继点接入进行管理。首先,通过对DTR协议中的数据传输延迟进行改进设计,针对相等时延并且时隙与现实不符的问题进行有效解决;其次,在系统局部信息处理中,基于局部阈值中继信息博弈协调策略,对信道接入进行优化,实现系统数据吞吐量的增加;最后,通过与传统DTR协议方法仿真对比,显示所提算法在低BPSK调制时的具有更小的传输延迟降低80%以上和,并且具有更高的算法稳定性,体现了其性能的优势。In the management of wireless spectrum system, relay node access is a very important link, but there are some problems in the process of local relay node intervention. The problem of energy saving and transmission efficiency is not considered. The local threshold relay information game is proposed to manage the wireless spectrum system. Firstly, the delay of data transmission in the DTR protocol is improved, and the problem of equal delay and time slot is solved effectively; Secondly, in the system of local information processing, based on the local threshold relay information strategy, the channel access is optimized to achieve the increase of system data throughput; Finally, by comparing with the traditional DTR protocol, the proposed algorithm can reduce the transmission delay of the proposed algorithm over 80%, and has higher algorithm stability, which reflects the advantages of its performance.
