Objective: To improve the performance of Transmission Control Protocol (TCP)by reducing packet loss, transmission errors, Round Trip Delay Time, optimizing the buffer size and using the energy efficient routing protocol. Methods: To achieve good performance, a feedback scheme is proposed which is called Feedback based TCP or TCP-F, so that the source can distinguish between Route Failure Notification (RFN) packet, allowing it to freeze its timers and stop sending packets. When the route is re-established, the source is informed through a Route Re-establishment Notification (RRN) packet, upon which it resumes by unfreezing timers and continuing packet transmissions. Findings: The performance of TCP on ad-hoc networks without and with feedback will be compared. The network performance will be determined in terms of throughput, time delay and routing overheads for different number of nodes. Improvements: It is assumed that in the event of route failures, as the route re-establishment time increases, the use of feedback provides significant gains in throughput as well as savings in unnecessary packet transmissions.
