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