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
