This paper proposes a new approach for TCP congestion control for future data networks, which is called TCP DCM+. DCM is the previous version, which uses TCP Westwood method of estimating the available bandwidth. The aim of the new protocol is to improve the performance and stability of DCM through using the corrected algorithm in TCP Westwood+ to estimate the available bandwidth. DCM+ is rate-based end-to-end approach, which applies the modification in both phases (SS, CA) of the sender. The results of the simulations show a huge improvement of throughput, in addition to the resulting stability. Many experts believe that the future of computer technology rests in mobile computing with wireless networking. TCP DCM+ is designed to be applicable in wired, wireless and MANETs networks. The simulations executed here are done using ns-3 simulator [16].
