本文介绍了一种用于移动自组织网络上多媒体业务的介质访问控制协议（称为预留CSMA/CA）的设计和性能。保留CSMA/CA协议基于由两个子层组成的分层方法。MAC协议的下层提供了一种使用CSMA/CA的基本访问方法，以支持移动自组织网络上的异步数据流量。上层子层通过在实际数据传输之前用三次握手预留槽位来支持实时周期性流量。利用软件仿真器对所提出的协议进行了验证，并在UNIX上实现。仿真结果表明，与IEEE 802.11标准相比，预留CSMA/CA在提供确定性延迟性能的同时，为实时周期性业务提供了更高的吞吐量。
This paper describes the design and performance of a medium access control protocol (called reservation CSMA/CA) for multimedia traffic over mobile ad-hoc networks. The reservation CSMA/CA protocol is based on a hierarchical approach consisting of two sublayers. The lower sublayer of the MAC protocol provides a fundamental access method using CSMA/CA to support asynchronous data traffic over mobile ad-hoc networks. The upper sublayer is designed to support real-time periodic traffic by making a slot reservation with the three-way handshake prior to actual data transmission. The proposed protocol has been validated using a software emulator which was carried out with the UNIX implementation. The simulation results show that the reservation CSMA/CA offers higher throughput for real-time periodic traffic compared to the IEEE 802.11 standard, while providing deterministic delay performance.
