Abstract

This paper presents a study of the methodology for the detection of congestion epochs and data transmission dynamical changes over mobile connections in the Universal Mobile Telecommunications System (UMTS) network. Dynamical changes in the data traffic occur in the Transmission Control Protocol (TCP), which is the protocol that regulates the data transmission inside the network. Using the concept of the recently introduced natural complexity measure of the Permutation Entropy (PE), the dynamical characteristics of the TCP inside the UMTS network are studied. It is shown that the PE can be effectively used to detect congestion epochs and the timely change in the dynamical pattern of the data transmission as regulated by the TCP. This is of crucial importance in order to prevent extended congestion epochs and the deterioration of the Quality of Service (QoS) in mobile networks.
