摘要：

在无线自组织网络中,协作分集技术不仅为物理层上提高系统抗衰落能力提供了有效手段,并且为网络跨层设计提供了有利的底层技术支持。协作通信技术与数据链路层上关键技术相结合,分别产生了协作自动请求重传(automatic repeat request,ARQ)机制和协作介质访问控制(medium access control, MAC)协议。本文讨论了传统MAC协议的现状,重点总结了在不同网络环境中以不同性能需求为目标的协作ARQ及协作MAC协议,并且给出了各种协议的基本规则和流程。

关键词: 跨层设计;协作分集;自动请求重传;介质访问控制

Abstract:

The emergence of cooperative diversity not only improves system capacity and effectiveness of resisting to fading, but also provides underlying technical support for cross layer design in Ad Hoc networks. With cooperative diversity introduced into the data link layer, cooperative ARQ schemes, and cooperative MAC protocols have been proposed. In this survey, we review the traditional MAC protocols. Then, the joint problems of medium access protocols and physical layer space diversity in different scenarios for different sakes are discussed. The rules and procedures of the cooperative ARQ and MAC protocols are given, respectively.

Key words: cross-layer design; cooperative diversity; ARQ; MAC
