摘　　要：为降低短波令牌协议(HFTP)令牌中继延迟,提高中继成功率,提出一种新型无冲突的分布式令牌中继协议(SQ-DTRP).该协议通过引入令牌中继子队列,提出增加通信对象项以最大限度保存网络实时状态信息,实现动态搜索令牌中继路径,克服了HFTP令牌中继机制存在的应答冲突和公平性问题.仿真结果表明,该协议令牌中继时延和中继成功概率明显优于HFTP,适合包括短波(HF)网络在内的各种无线网络使用.In order to improve the relay delay and successful relay probability performances of high frequency token protocol（HFTP）,derived from HFTP token relay protocol,a distributed collision-free token relay protocol named sub queue-dynamic token relay protocol（SQ-DTRP） is presented,Through the introduction of the communication object column in the relay sub-queue,the real-time network status are reserved as much as possible for the dynamic searching of token relay paths. As a result, potential collisions in acknowledgement to SOLICIT_ RELAY and the token passing impartiality problems are well corrected by this protocol. Simulations indicate that the token relay delay and token relay success probability of SQ-DTRP are better than HFTP, which makes it very suit for high frequency （HF） network and other kinds of wireless networks, too.
