摘要

本文研究了一种支持实时服务的新型媒体访问控制机制。主要目标是为在自组织网络中运行的自主移动节点对提供恒定比特率的语音呼叫服务。本文考虑了一种基于时隙预约的MAC来提供实时语音呼叫，并提出了一种新的MAC，称为时隙预约协调函数(time-slot reservation coordination function, TRCF)。除了这种同步类型的MAC协议开发之外，所提出的协议还使用马尔可夫链建模以预测其行为。对TRCF的性能进行了分析推导，得到了一个呼叫连接的平均等待时间和吞吐量等性能指标。

Isochronous MAC Protocol for Real-Time Service Support in MANET

In this paper a novel medium access control mechanism is investigated as a means to support realtime services. The primary goal is to provide constant-bit-rate voice call services to pairs of autonomous mobile nodes operating in ad hoc networks. Here, a time-slot reservation based MAC is considered to provide real-time voice calls, and a new MAC called the time-slot reservation coordination function (TRCF) is presented. In addition to this isochronous type MAC protocol development, the proposed protocol is modeled using a Markov chain in order to predict its behavior. The performance of TRCF is analytically derived and the performance measures such as average wait time taken for a call connection and throughput are obtained.
