MANET中基于速率的流量控制算法研究

Research on Rate-Based Flow Control in MANET

由于MANET中网络的动态变化特征,TCP隐含式AIMD流量控制不适应于该领域。本文介绍了基于速率的显式流量控制策略(EXACT),并分析了它对网络中再路由和带宽变化的反应。在高速动态变化的MANET环境下,通过ns-2系统模拟,本文评价了EXACT在网络传输公平和效率等方面的性能。

The implicit flow control AIMD in TCP performs poorly in MANET because of the dynamic changes in this environment. An explicit rate-based flow control scheme （EXACT） is explored in the paper to suit for the re-route and bandwidth variation of wireless links.Based on the ns-2 simulations,the results show that EXACT has much advantage in term of fairness and efficiency in highly dynamic MANET.
