Minimising RTT across homogeneous 802.11 WLANs with CAIA Delay-Gradient TCP (v0.1)
Common loss-based TCP algorithms (such as NewReno) are known to induce significant additional latency over 802.11 wireless LANs (WLANs), negatively impacting multimedia traffic sharing the same network. Using live experimental trials (under FreeBSD 9.0 on the Emulab 802.11 testbed) we show that CAIA’s delaygradient TCP (CDG) version 0.1 induces two to seven times lower latency than NewReno and ...
متن کاملCombined Numerical Optimization of TCP and Routing Protocol Parameters in Wireless Ad Hoc Networks
Much research is currently ongoing in the area of wireless, local-area networks (WLANs). Compared to wired protocols like IEEE 802.3, wireless protocols, like IEEE 802.11, suffer in areas such as communication errors, data rate, and throughput,. Because of this, many of these investigations seek enhancements to the 802.11 protocol, as well as to other systems in the network stack. A significant...
متن کاملAnalytical Study of TCP Performance over IEEE 802.11e WLANs
IEEE 802.11 Wireless LAN (WLAN) has become a prevailing solution for broadband wireless Internet access while the Transport Control Protocol (TCP) is the dominant transport-layer protocol in the Internet. Therefore, it is critical to have a good understanding of the TCP dynamics over WLANs. In this paper, we conduct rigorous and comprehensive modeling and analysis of the TCP performance over th...
متن کاملTime Control for TCP Fairness in WLANs
Wireless local area networks (WLANs) based on IEEE 802.11 standard have been widely used in infrastructure and ad hoc networks. Although the MAC layer of 802.11 WLAN provides fairness in accessing the wireless channel, the channel capacity is allocated unfairly among stations and flows due to effect of the upper layer protocols such as TCP and asymmetric network conditions. In this dissertation...
متن کاملA queueing model for HTTP traffic over IEEE 802.11 WLANs
We consider an IEEE 802.11 based wireless LAN where an access point is used to connect a fixed number of users to the Web or to a shared file system. Users alternate between activity periods (corresponding to the download of a file) and idle periods (corresponding to think times). We first consider the interaction of TCP with the IEEE 802.11 MAC protocol, and get approximate expressions for the...
