| 摘 要： | 结合多信道和双向信道预留的策略,本文提出了一种新的应用于Ad Hoc网络的多信道媒体接入算法-NBMC算法,并对其吞吐量进行了性能分析。仿真实验结果表明,与IEEE802.11DCF相比,NBMC算法使Ad Hoc网络上的TCP吞吐量和各TCP流信道占用的公平性都得到了有效的改善。

| Abstract: | A novel bidirectional multi-channel (NBMC) medium access algorithm is proposed for ad hoc networks in this paper.It integrates the multiple transmission channel scheme and the bidirectional RTS/CTS channel reservation algorithm.A theoretical analysis of the throughput and simulation results show that the TCP performance is improved obviously compared with the IEEE 802.11DCF protocol. |
