| 摘 要： | 本文在现有多信道MAC协议的基础上将地理位置信息引入MAC层，提出一种新的GM-MAC协议。该协议以节点间距离作为分配信道的优先级，为近距离传输时的QoS提供更好的保障。本文给出了协议的格式，阐述了协议的操作步骤并对吞吐量做了分析。仿真结果表明，时延、吞吐量等方面有更好的性能。

| Abstract: | This paper presents a new protocol called GM-MAC that introduces geographic information into MAC based on multiple channels.It agrees the shortest distance between two nodes has a better priority and provides better QoS.The format is defined in this paper,the operational steps of the protocol is explored,and the throughput is analyzed.The simulation results show that it can decrease the average end-to-end delay and improve the throughout. |

| Keywords: | ad hoc network geographic location multi-channel time division multiple access medium access control protocol |
