摘　　要：采用一种增强MANET网络QoS性能的MAC机制,引用“接力传输”和“接力中断”两种新的操作方法。对高优先级业务,MAC帧由源端被“接力”传输至目的端;对不同优先级的业务,产生不同次数的“接力中断”。每次接力中断增加一次信道竞争,由此达到不同优先级业务的区分。NS-2仿真表明此机制的有效性。A new MAC mechanism with QoS enhancement for MANET is proposed. Two new terms named ＂frame-re- lay and ＂relay-interruption＂ are introduced for different priority applications. With frame-relay, top priority applications can be delivered from source node to destination with minimum contention. For different priority traffic, different times of ＂frame-interruption＂ are applied. NS-2 simulation demonstrates the feasible of the proposed approach.
