Exploiting GoP patterns for video traffic control over wireless networks Exploiting GoP patterns for video traffic control over wireless networks Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-102012enWireless networks face the challenge of being able to provide high Quality of Service (QoS) to users running different multimedia applications. As the number of applications continuously grows and multimedia users have widely different and contradictory QoS requirements, the task of the network designer in next generation wireless networks is further aggravated. Efficient Call Admission Control (CAC) and Traffic Policing (TP) mechanisms can significantly help towards improving user QoS. In this work, we focus on both the CAC and TP problems. We propose and evaluate new mechanisms which take into account the differentiated service contracts of wireless cellular video users and the Group-of-Pictures (GoP) patterns at the video traces. Both mechanisms are shown to outperform existing work in the relevant fields.http://creativecommons.org/licenses/by/4.0/2081 - 2086 IEEE Wireless Communications and Networking Conference Koutsakis Polychronis Κουτσακης Πολυχρονης Sotiropoulos, Jean-Marc, 1963- Delimargas ,A Institute of Electrical and Electronics Engineers Communication systems, Wireless Wireless data communication systems Wireless information networks Wireless telecommunication systems wireless communication systems communication systems wireless wireless data communication systems wireless information networks wireless telecommunication systems
