2020 International Symposium on Performance Evaluation of Computer and Telecommunication Systems

July 20-22, 2020, Madrid, Spain

Due to the COVID-19 outbreak, and for the health and safety of our attendees, the 2020 International Symposium on Performance of Computer and Telecommunication Systemts (SPECTS) will now be a virtual event.

The goal of this annual conference is to provide a forum for professionals and researchers to discuss and disseminate the most promising contributions on performance evaluation of computer and telecommunication systems. Papers describing results of theoretic and/or practical significance are solicited. Experimental, modeling, analysis, and simulation studies as well as testbed deployment, field trials and experiences gained are all in the scope of the conference. Work presenting novel performance evaluation methods or providing insights on design and runtime tradeoffs are particularly encouraged.

SPECTS 2020 will be co-located with the 2020 Summer Simulation Conference (SummerSim'20). SummerSim'20 is a premier annual international conference by The Society for Modeling and Simulation International (SCS).

Keynote

Modeling and Simulation of Cellular Networks: formalizing the models

Summary

Modeling and Simulation methods have been used to better analyze the behavior of complex physical systems and it is now common to use simulation as a part of the technological discovery process. Formal M&S appeared in order to try to improve the development task of very complex simulation systems. Some of these techniques proved to be successful in providing a sound base for the development of discrete-event simulation models, improving the ease of model definition and enhancing the application development tasks, reducing costs and favoring reuse.

This is particularly important in the development of computer networks. Future mobile networks should provide high data rate services for their customers regardless of their location. This is a challenging task, specifically for the users in the edge of the cell's area. To overcome this problem, Long Term Evolution Advanced introduced Coordinated Multi-Point (CoMP) and other advanced techniques were introduced. In this talk, we will present different methods developed recently for the next generation of mobile networks, based on CoMP and other techniques. We discuss different M&S techniques employed, and new results obtained that show that these methods can improve the performance for end users.

We will discuss Upload User Collaboration (UUC); an algorithm can be combined with CoMP to enhance the upload performance of cell-edge users.

We will then discuss new methods to improve the performance of video traffic in cellular networks. We present different algorithms that combine Device-to-Device (D2D) communication, introduced by the Long Term Evolution-Advanced standard (LTE-A). We present two algorithms for improving the throughput of video transmission in cellular networks. The algorithms are called Cached and Segmented Video Download (CSVD), and DIStributed, Cached, and Segmented video download (DISCS).

Finally, we discuss new methods for video streaming applications in Cellular networks. Providing high Quality of Experience (QoE) video streaming services is becoming a challenge due to the limited capacity in cellular networks and the impairments of transmission over radio links (e.g., path-loss and fading). As such, the parameters of the wireless communication on the radio access network between the Base-Station (BS) and User Equipment (UEs) have an effect on video streaming QoE. We study the impact of the wireless trans-mission parameters in Long Term Evolution-Advanced (LTE-A) networks on video streaming QoE. We consider both cell level and link level parameters. Dynamic Adaptive Streaming over HTTP (DASH) -based video streaming is considered here. We built a model for an LTE-A network and ran multiple simulations with various scenarios. We present and analyze the results to evaluate different video streaming QoE metrics, and to see how they are affected by the various cellular communication parameters.

These research results present a real-world use of formal Discrete EVent System specifications (DEVS) for modeling mobile networks, and practical case studies with industrial relevance (algorithms, based on the DEVS studies, were patented by Ericsson Inc. for commercialization). The studies compare different approaches and show how to improve the cell-edge users' upload performance, and it reduces the time required to upload a file.

Special Session

Cloud and Fog Computing Resource Management and Performance Engineering

by Carlos Guerrero

Summary

Cloud architectures have evolved to scenarios such as Fog and Edge computing, where the computation and storage capabilities are located closer to the users in cloudlets or dedicated devices. Fog architectures mainly differs from Cloud ones in terms of resource capacity, geographical distribution, network latency, node heterogeneity and user mobility. This makes us to rethink the current resource management policies and the performance evaluation and optimization techniques. Solutions to this problematic need to be addressed by considering the Cloud and Fog computing as a continuum with the distribution of the resources and the computing services along the different levels of the architecture. The aim of this special track is to provide a forum to exchange ideas and generate collaborations between researchers from the fields of, but not limited, Cloud Computing, Fog Computing, Resource Management and/or Performance Engineering.
