The major aim of this research work carried out on Ad hoc networks is to develop a model which improves the performance of Transmission Control Protocol (TCP) compared to the existing TCP. On the basis of the research work presented by different researchers all over the world, a method was implemented and it combines feedback based approach as well as the adaptive approach to enhanceTCP performance. To get TCP with enhanced performance, the working of standard TCP was changed to either Full Congestion window-TCP or Partial Congestion window TCP. From the simulation it was found that Partial Congestion window-TCP is more suitable for lossy links like internet. It is found that Full Congestion window TCP is more suitable and appropriate in high usage of bandwidth applications. This new approach combines the adaptive back-off with feedback scheme to make TCP to work better than traditional TCP. This research brought the intelligence wherein this protocol will be able to detect the conditions of the network as well as the various external factors like power and then choose whether to use Full Congestion window TCP or Partial Congestion TCP.
