The aim of this paper is to present DCM+, a new congestion control protocol\nfor data networks. It stands for Dynamic Congestion control for Mobile networks.\nNew metrics have been newly invented and introduced like normalized\nadvancing index (NAI) and complete transmission time (CTT). The simulations\nare done for a simple single-hop-topology (sender-router-receiver ). The\noutcomes of this protocol are excellent and, in most cases, better than other\napproaches. The excellent properties of our proposed protocol were possible\nthrough tracking the available slow-start threshold. We achieved performance\nimprovement, minimized end-to-end delay and large reduction in transmission\ntime. DCM+ was able to combine many advantages at same time of the\nprotocols NewReno and Westwood+. The results show, that DCM+ is extremely\nadequate for different types of networks. Feedback as main principle\nof control theory was used to control the congestion in the network. The parameters\nRound-Trip-Time (RTT) and Retransmission Timeout (RTO) are\nused as feedback signals to adjust the next congestion window (cwnd).
