Mobile Ad-Hoc networks are the collection of independent mobile nodes with no fixed infrastructure. The high mobility of nodes is responsible for the congestion of the network and this congestion may occur due to various other reasons. TCP’s robust behaviour is mainly due to its reactive behaviour on congestion and retransmissions are done to ensure reliability. Although many reasons may be there TCP, which is a reliable End-to-End transport layer protocol finds it difficult to distinguish between the losses and considers the congestion losses to be due to queue overflow or queue delay. The non congestion losses like mobility, power depletion of nodes and link failure are not considered by the algorithms. Hence there must be proper algorithms to detect the non-congestion and congestion losses. In this paper the variants of TCP are discussed these variants provide a method to control congestion losses in the network whether it may be due to congestion or non-congestion. These mechanisms provide methods for re-transmission, congestion control and pattern to avoid congestion.
