摘　　要：作为一种新兴的无线组网技术,无线网格网在灾后救援、临时大型活动及时通信和家庭办公多媒体数据交互等多个领域都有着广阔的应用前景。介绍了无线网格网的网络结构和标准化协议,并针对MAC协议设计的两个关键技术:时隙分配和跨层设计进行了阐述和总结,为解决现有无线网格网协议中时隙利用率低和多跳传输效率不高提供了依据。As an emerging wireless networking technique,wireless mesh network has a vast application prospect in the fields of rescue after disaster,instant messaging for temporary large？scale activities and telecommuting multimedia data interac？tion. The network structures and standardized protocols of the wireless mesh network are introduced. The two key technologies of time slot allocation and cross？layer design for MAC protocol design are presented and summarized,which provides the basis for improving the time slot utilization ratio and multi？hop transmission efficiency in the existing wireless mesh network protocols.
