Progress Of Different TCP Variant

At the beginning of development of network TCP were designed assuming that communication is using wired network, but recently there is huge demand and use of wireless network for communication. TCP protocol using wireless network unable to handle causes of packet losses in wireless network and also causes of unnecessary delay .So the biggest challenge in MANET is design of TCP variant which should give best performance in all scenarios. Uptil now more than dozens of variants designed and modified by research community but not a single TCP variant performance well in all scenarios. Such as congestion, link failure, signal loss, interference as well as rod and grid network topologies. As some of TCP-variant performs well in particular scenarios but degrades in other scenarios. Our objective was to design such a TCP variant which has to perform optimum in every network scenario For Example congestion, link failure, signal loss and interference scenario as well as chain and topologies
