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。
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.
