摘要

基于RTS-CTS握手协议通过有效地消除隐节点问题来实现“可靠单播”，但这些解决方案并不能直接或有效地生成解决“可靠多播”问题;多播仍然是无线AD hoc网络中最努力的操作。本文提出了一种简单、轻量级、自稳定的MAC协议，即忙消多址(BEMA)协议，用于解决可靠组播问题。BE MA授予对信道的按需访问——而不是像基于TDMA的方法那样分配固定插槽——并支持流量的优先级，从而为具有可靠性和服务质量要求的应用程序提供了有用的构建块。

A MAC Layer Protocol for Priority-based Reliable Multicast in Wireless Ad Hoc Networks

RTS-CTS handshake based protocols achieve "reliable unicast" by eliminating the hidden node problem effectively, however, these solutions are not directly or efficiently gener- alizablefor solving the "reliable multicast"problem; multicast remains as a best-effort operation in wireless ad hoc networks. Here, we present a simple, light-weight, and self- stabilizing MAC protocol, namely busy elimination multiple access (BEMA) protocol, for solving the reliable multicast problem. BE MA grants on-demand access to the channel-rather than assigning fixed slots as in TDMA based approaches-and supports prioritization of traffic, thereby providing a useful building block for applications with reliability and quality-of service requirements.
