多接口协作的高吞吐多信道MAC协议
High-throughput multi-channel MAC protocol with multi-interface cooperation
摘要
Abstract
Low utilization of the interface always exists in multi-interface multi-channel (MIMC) medium access protocol.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 impact 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.关键词
