| 摘 要： | 在ad hoc移动自组网中，隐藏终端和暴露终端问题严重影响着MAC层的网络吞吐量性能。为了更好的解决隐藏／暴露终端问题，文献[3，4]提出了一种信道接入方法，即联合检测法。论文对此算法进行了改进，对RTS／CTS控制分组采用了载波侦听／冲突检测（CSMA／CD）策略，而对数据分组采用了基于发射端的码分配法。通过理论分析和仿真，表明提出的信道接入策略可获得较大吞吐量增益。

| Abstract: | In ad hoc networks,hidden-and the exposed-terminal problems can severely reduce the system throughput in MAC layer.To address these problems,a channel access method exploiting joint detection of overlapping packets is proposed by Kota in [3]].In this paper,we propose an improvement on the method,which uses CSMA/CD medium access protocol for the RTS/CTS control packets and transmitter-based code assignment for spreading the data packets.The performance of the proposed channel access method has been investiga... |
