中文摘要：

提出了一种单信道多跳Ad Hoc网络的媒体接入层协议．利用全向天线的特点，协议控制帧捎带路由信息，使邻居节点获知节点问路由状态．上游节点的ACK应答直接触发下游节点的CIS握手，形成CTS／DATA／ACK三维交互机制．协议可有效减少网络的握手开销，降低重负载时握手帧的冲突概率．仿真表明，协议可适应不同的拓扑．最好情况下，协议较IEEE802．11协议的吞吐量约提升16．1％，端到端延时约降低16．8％．改善了多跳Ad Hoc网络性能．

英文摘要：

A novel medium access control （MAC） protocol for the single-channel multi-hop Ad Hoc network is proposed. Using omni-directional antenna, the control flame tagged with the muting information can be sensed by the neighboring nodes. Furthermore, the ACK message send by the upstream node triggers the CTS-only handshake of the downstream node and,the three-way exchange （CTS/DATA/ACK） is performed. This mechanism lowers the probability of the control message collision in heavy load network. Simulation results demonstrate that with various topologies our proposed scheme can outperform IEEE 802.11 with throughput and delay betterment.
