TCP-DCR: A Protocol For Tolerating Wireless Channel Errors

The popularity of wireless networking has increased dramatically over the past few years. However, integrating high delay, high channel error wireless networks with existing wired networks still posses significant challenges to the research community. Incorporating end-to-end congestion control for wireless networks is one of the primary concerns. Considering that TCP is the most prevalent congestion control protocol used on the wired Internet, compatibility issues would necessitate its use on wireless networks as well. But, TCP was designed to work well in networks with low channel error rates and when used in wireless networks which are generally characterized by larger channel error rates, the losses due to channel errors also get treated as congestion losses, resulting in suboptimal performance.
