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.
