Abstract

This paper offers a solution to the problem of incompatibility of the TCP designed for networks with fixed routers and the Ad-hoc network, which sometimes its mobile hosts act as routers causing a routing failure. In order to overcome this obstacle, this work presents three Ad-hoc TCP novels. The first novel is adding a controller to Ad-hoc TCP queues; this controller works as a memory in the TCP’s queue by saving the change rate of the previous error signals, then using it as a measure to change future error signal conduct. The second one is a comparison among the three Ad-hoc TCPs, which use different controllers, TCP PI/PD/PID. Finally, the models show promising results since all three Ad-hoc TCPs’ results surpass the traditional TCP’s result. Besides, the comparison process specified the best Ad-hoc TCP among the three, and that is the TCP/PID with Rise Time=3.472 ms, Overshoot=5.851%, Undershoot= -0.8264%, and Setting Time = 0.15 sec.
