| 摘 要： | 针对无线自组网络中存在的隐藏、暴露终端问题，提出了一种基于CSMA／CA协议改进的无线自组网MAC层协议，在CSMA／CA协议的基础上增加RTS／CTS握手信号，提高了网络的性能。同时，文章通过理论分析和仿真结果两种方式对基本的CSMA／CA与带RTS／CTS的CSMA／CA协议在多跳无线自组网下的吞吐量和时延进行了比较分析，证明了改进后的协议的优势。

| Abstract: | For the hidden and exposed terminal problem in wireless Ad Hoc networks, this paper proposes a improved wireless Ad Hoc MAC protocol based on CSMA/CA protocol. It enhances the performance of the network by using RTS/ CTS control packets on CSMA/CA. At the meantime, this paper compares and analyses the throughput and delay between basic CSMA/CA and CSMA/CA with RTS/CTS in wireless Ad Hoc network, and proves the advantage of the improved protocol. |
