中文摘要：

多接口多信道MAC协议存在接口利用率不高等问题.为此,提出MIC-MAC协议在多接口节点模型中 增加虚拟MAC层,利用单接口的成功握手信息建立源-目标节点之间所有接口同步传输的关系,提高了吞吐量 和控制帧效率.另外,成功传输的节点选取当前信道作为下次传输的决策信道可以有效改善隐藏终端问题.实验 结果表明在单跳网络中,与MIMC-SMAC、IEEE 802.11协议相比,吞吐量分别提高了 100%~200%; 在多跳网络 中有效改善了碰撞和隐藏终端问题.

英文摘要：

Low utilization of the interface always exists in multi-interface multi-channel （MIMC） medium access proto-col. Therefore, the multi-interface cooperating （MIC） mechanism was proposed. A virtual MAC layer was designed in multi-interface node and multi-interface cooperative mechanism through one successful handshake of single interface to establish the synchronous transmission relationship between source-destination nodes all interface and data channel groups, thus improving the throughput and efficiency of control frame.Furthermore, nodes with successful transmission choose the current channel set as decision-making channels of the next transmission,which can effectively reduce the im-pact of hidden terminal. The simulation results of MIC-MAC protocol show that the throughput has increased by 100% to 200% compared with MIMC-SMAC protocol and IEEE 802.11 in single hop network, the collision and hidden terminal problem have also been greatly optimized in multi hop network.
