摘要

先前对manet中TCP性能的研究在很大程度上假设802.11 RTS/CTS机制在整个连接时间内保持完全有效。在这项工作中，我们评估了利用802.11握手的其他操作模式对TCP性能的影响，同时保持与原始规范的兼容。为了确定不同操作模式之间的good - put差异的来源，我们引入了两个新的指标来描述TCP连接的空间连接，然后在使用不同的RTS/CTS策略时，使用它们来解释TCP good - put在字符串和网格拓扑中的差异。

The Effect of the RTS/CTS Handshake on TCP

Previous research enquiries into TCP performance in MANETs have largely assumed that the 802.11 RTS/CTS mechanism remains in full effect throughout the connection time. In this work we evaluate the effects on TCP goodput of utilising other modes of operation for the 802.11 handshake whilst remaining compliant with the original specification. To identify the source of the goodput discrepancies amongst the different modes of operation we introduce two new metrics to characterise spatial connection along a TCP connection and then use them to account for TCP goodput in string and mesh topologies when using different RTS/CTS strategies.
