Round Trip Times (RTT) are recognized as an important indication of a network's performance, particularly in congestion protocol and bandwidth measurement tools. We have studied and compared the characteristics of RTT on wireless and wired networks. We have conducted extensive experiments from diverse network environments and performed quantitative analyses on RTT variability. We found that RTTs on wireless networks exhibit a greatly larger mean and standard deviation; 10 ms bigger than those of a wired network. The impact of packet size, due to a wireless channel is also significantly higher. We have also shown that through a simple set of tests, one can classify whether or not a wireless network has been involved. Our study and findings shed light on adaptive protocol design as well as realistic simulation scenarios for other research.The former may have a single wireless access point (AP) as a simple range extender for a wired network. ... In considering wireless environments, we chose three different environments: a#39;at homea#39; as Data Set I, a#39;at worka#39; as Data Set II, and a#39; on aanbsp;...
