X. CONCLUSION In this paper we have presented a performance analysis of the Wireless Integrated Multiple Access (WIMA) protocols. These schemes, which combine the pure-reservation NIFFL are especially well suited to satellite networks and to highspeed wireless terrestrial networks in which the round-trip propagation delay is greater than the data-packet duration, although they are also appropriate for environments in which propagation delay is less than a packet duration. The techniques we have developed to exploit the structural properties of the two-dimensional first-order Markov chain that characterizes this scheme have been shown to permit the efficient and accurate evaluation of data-packet delay and voice-call blocking probabiliy. Performance results illustrate the dependence of performance on system parameters, and demonstrate the improved performance that can be achieved through the use of the movable-boundary version as compared to the fixed-boundary version. Trade-offs between data-packet delay and voice-call blocking probability show the importance of the parameter Vmax, the threshold used to control access of voice calls to the system. |

结论 在本文中，我们提出了一个性能分析的无线集成多址协议（WIMA）。该方案与纯保留NIFFL相结合，特别适合卫星网络和陆地高速无线网络，该网络的数据往返传输延迟要大于数据包的持续时间，尽管它也适用于往返传输延迟要小于数据包持续时间的环境。我们已经开发了一种技术来确定二维一阶马尔可夫链的结构性质，该链可以对本方案进行表示，结果表明，该方法可以对数据包延迟和呼叫阻断的可能性进行有效、准确的评估。测试结果表明系统性能和系统参数有关，与固定边界的版本相比，使用可移动边界的版本可以提高系统的性能。权衡data-packet延迟和voice-call阻塞概率显示参数空间门槛的重要性 ,该门槛被用来控制系统的语音接入。 |
