Abstract:

The Transmission Control Protocol (TCP) was designed for reliable fixed network, it treat package loss or delayed as network congestion. But in Mobile Ad Hoc networks, other factors such as channel error, network partition and route changes also could invoke package loss, at the moment slow-start and fast recovery property of TCP will decreased the transmission performance. In this paper, we firstly discussed several main factors which infect TCP performance in Ad Hoc networks, and then presented an overall view on some representative improved schemes of TCP in Ad Hoc networks. Finally, we had an analysis and compare on these schemes.

Key words: TCP, Ad Hoc, congestion
