摘要：
In this paper, we propose an efficient parallel transmission MAC protocol based on geographical location information of nodes. The protocol breaks through the limit of parallel transmission based on traditional CSMA MAC protocols, for this protocol exploits nodes' geographical location information to achieve the parallel transmission of exposed terminal, so as to enhance the reuse efficiency of the valuable wireless channel resources. According to the location coordinates of the nodes, this paper explores the feasibility analysis of parallel transmission of exposed terminal node, and completes the parallel check. Simulation results show that, compared to IEEE 802.11 DCF protocol, the proposed MAC protocol can significantly improve the average throughput of the network, reducing data transmission delay, and effectively improving the efficiency and performance in Multihop Wireless Networks.
