| 摘 要： | 文章提出了一种新的基于跳变预约的AdHoc网络多信道媒体接入协议(NHRMC),它综合了基于ATIM窗口的同步机制和基于等级的信道预约算法,有效地解决了多跳网络环境下隐终端问题。吞吐量性能分析和仿真实验结果表明,与IEEE802.11DCF的RTS/CTS机制相比,在一定假设条件下,网络的性能得到了明显的改善。

| Abstract: | A new Hop-Reservation Multi-channel Medium Access protocol(NHRMC) is proposed for Ad Hoc wireless networks.It integrates the synchronous mechanism with ATIM window and channel reservation algorithm with rank to effectively solve hidden terminal problem caused by multi-channel environment.The theoretic analysis of throughout and simulation results show,compared with RTS/CTS hand mechanism with single channel,the performance is improved obviously,especially for the transmission of larger packets. |
