传统无线令牌环协议具有一定的错误检测机制,但没有对其服务质量(QoS)性能进行系统研究和分析.Rip-ple和改进型无线令牌协议等空间复用令牌协议令牌传递不同步,没有任何错误检测机制.基于此,提出一种令牌自产生的概念,通过将其与固定令牌持有时间机制相结合,采用计时器队列实现空间复用令牌协议多令牌同步并行传递,在此基础上提出基于邻居监听的错误检测机制,并对算法的QoS指标进行了理论分析和仿真.仿真结果表明,该机制可及时检测网络错误并进行有效处理,正确检测概率较高,适合在无线空间复用令牌网络中使用.
Traditional wireless Token Ring protocols have some mechanism for error detection but do not systematically investigate and analyze their Quality of Service (QoS) performance Spatial Multiplex Token Protocol Token Passthrough RIPip and Modified Wireless Token Protocol Synchronization and no error detection mechanism.Based on this, a concept of token self-generation is proposed, which is implemented by using a timer queue to implement the spatial multiplexing token protocol multi-token synchronization by combining it with the fixed token holding time mechanism And based on which the error detection mechanism based on neighbor monitoring is proposed and the QoS indexes of the algorithm are theoretically analyzed and simulated.The simulation results show that the mechanism can detect network errors in time and deal with them effectively and the correct detection probability is high , Suitable for use in a wireless space multiplexed token network.
