摘要 讨论了如何利用IEEE 802.16j的多跳中继技术,来提高车辆网路中车辆用户(SS)与Internet基站(BS)之间的吞吐量.研究了在SS和BS位置已知的情况下,通过选择最佳中继站,来最大限度地提高SS与BS之间的吞吐量.将上述问题纳入到高速公路的流动模型中,借助非线性优化方法来求解,最终确定SS与BS之间的最佳中继站的位置,以获得最大吞吐量.最后通过NS-2仿真实验验证了该算法的有效性,结果表明,相比于不使用中继,该方案使端到端吞吐量的期望值得到了提高. The use of IEEE 802.16j of multihop relay（MR） technology was discussed to improve the throughput between the vehicular subscriber station（SS） and the Internet base station（BS） in the vehicular network.In the case that the position of SS and BS are known,by selecting the optimal relay stations,the throughput between SS and BS can be maximized.By incorporating a highway mobility model,with the help of a nonlinear optimization method,the location of the optimal relay which obtained max throughput was ascertained.Finally,the effectiveness of this algorithm was verified through NS-2 simulation experiments,the results showed that comparing the cases without relay,this program increases the expected value of the end to end throughput.
