TLDR
I-TCP is described, which is an indirect transport layer protocol for mobile hosts, which utilizes the resources of Mobility Support Routers (MSRs) to provide transport layer communication between mobile hosts and hosts on the fixed network.Abstract:
IP based solutions to accommodate mobile hosts within existing internetworks do not address the distinctive features of wireless mobile computing. IP-based transport protocols thus suffer from poor performance when a mobile host communicates with a host on the fixed network. This is caused by frequent disruptions in network layer connectivity due to i) mobility and ii) unreliable nature of the wireless link. We describe I-TCP, which is an indirect transport layer protocol for mobile hosts. I-TCP utilizes the resources of Mobility Support Routers (MSRs) to provide transport layer communication between mobile hosts and hosts on the fixed network. With I-TCP, the problems related to mobility and unreliability of wireless link are handled entirely within the wireless link; the TCP/IP software on the fixed hosts is not modified. Using I-TCP on our testbed, the throughput between a fixed host and a mobile host improved substantially in comparison to regular TCP.read more

A comparison of mechanisms for improving TCP performance over wireless links
TL;DR: The results show that a reliable link-layer protocol that is TCP-aware provides very good performance and it is possible to achieve good performance without splitting the end-to-end connection at the base station.

End-to-End Arguments in System Design.
TL;DR: A design principle is presented that helps guide placement of functions among the modules of a distributed computer system and suggests that functions placed at low levels of a system may be redundant or of little value when compared with the cost of providing them at that low level.
