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。
Low uti1ization of the interface a1ways exists in mu1ti-interface mu1ti-channe1(MIMC)medium access protoco1.Therefore,the mu1ti-interface cooperating(MIC)mechanism was proposed.A virtua1 MAC 1ayer was designed in mu1ti-interface node and mu1ti-interface cooperative mechanism through one successfu1 handshake of sing1e interface to estab1ish the synchronous transmission re1ationship between source-destination nodes a11 interface and data channe1 groups,thus improving the throughput and efficiency of contro1 frame.Furthermore,nodes with successfu1 transmission choose the current channe1 set as decision-making channe1s of the next transmission,which can effective1y reduce the impact of hidden termina1.The simu1ation resu1ts of MIC-MAC protoco1 show that the throughput has increased by 100% to 200% compared with MIMC-SMAC protoco1 and IEEE 802.11 in sing1e hop network,the co11ision and hidden termina1 prob1em have a1so been great1y optimized in mu1ti hop network.
