In this study we tested the average delay and packet loss performance of access networks under variable bit rate (VBR) video traffic. We used ns-2 simulator to perform the simulations, and actual as well as synthetically generated ON/OFF sources with ON and OFF times taken from exponential or Pareto distributions are used as inputs to the simulated networks. To make sure that the synthetic sources have vbr-video like characteristics we chose the parameters of these sources such that their Hurst parameter is as close to I as possible. We then tested the performance of a network when data produced by these sources is applied as input. The results show that both actual and synthetic sources produce similar results and that the access networks should have at least 1 Mbps speeds to support acceptable quality video transmission.

Evaluation of Terahertz Channel in Data Centers
MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29)
Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
Cost aware TCP scheduler for bandwidth aggregation
Ağırbaş, Serhat; Koçyiğit, Altan; Sevgi, Cüneyt; Department of Information Systems (2018)
Constant bit rate, time sensitive data delivery is needed for many network applications and these applications usually require high throughput and less variable delay. When such applications run on mobile devices, the bandwidth available and the other characteristics of the primary network connection may not be sufficient to provide necessary quality of service. On the other hand, most of the mobile devices are multihomed that is they are equipped with more than one network interface, hence they can be conn...
Impact of scalability in video transmission in promotion-capable differentiated services networks
Gurses, E; Akar, Gözde; Akar, N (2002-09-25)
Transmission of high quality video over the Internet faces many challanges including unpredictable packet loss characteristics of the current Internet and the heterogeneity of receivers in terms of their bandwidth and processing capabilities. To address these challanges, we propose an architecture in this paper that is based on the temporally scalable and error resilient video coding mode of the H.263+ codec. In this architecture, the video frames will be transported over a new generation IP network that su...
Implementation and performance of parallellised turbo decoders
Yılmaz, Ali Özgür; Yılmaz, Ayşen (2011-01-04)
In this study, the authors discuss the implementation of a low latency decoding algorithm for turbo codes and repeat accumulate codes and compare the implementation results in terms of maximum available clock speed, resource consumption, error correction performance and the data (information bit) rate. In order to decrease the latency a parallellised decoder structure is introduced for these mentioned codes and the results are obtained by implementing the decoders on a field programmable gate array. The mem...
Optimized Multi-Constrained Quality-of-Service Multipath Routing Approach for Multimedia Sensor Networks
Hasan, Mohammed Zaki; Al-Turjman, Fadi; Al-Rizzo, Hussain (2017-04-01)
Modern multimedia sensor networks impose strict constraints on both the delay and energy consumption when time-critical data must be reported to the sink within a limited bandwidth without any loss. Failure to transmit an event to the sink occurs for many reasons, including inherence limitations of sensors, power consumption, and reliability. We propose a mathematical model for a novel quality-of-service (QoS) routingdetermination method. The proposed scheme enables determining the optimal path to provide a...
