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.
