100 Most Frequent Errors in Performance Evaluation

posted Oct 3, 2017, 12:06 PM by Tobias Hoßfeld   [ updated Oct 3, 2017, 12:07 PM ]

Call for Contributions
Contributions that report typical errors found in the literature related to performance evaluation in the communications and networking area are sought. The objective is to prepare an open source book containing 100 typical errors in the hope that such a book may help researchers and practitioners avoid these errors. The 100 errors are interesting for PhD students as well as bachelor and master students who are evaluating the performance of systems by means of measurements, simulations, experiments, or analytical approaches. Typical examples are the random generation of points in a circle or the simulation of non-stationary Poisson processes, see example pdf.

Submission 
Submissions will be peer-reviewed. Authors are requested to use the latex template for their contributions. Contributions shall be between 2 and 6 pages long and include (a) description of question at hand, and associated problem, (b) illustrative description of the error, (c) description of one or several possible solutions. For submitting an article, please complete the online form and send the contribution via email to contact@100errors.info. Please have a look at the list of errors if a similar contribution is already submitted. Accepted contributions will appear in an open source book.

ITG FA 5.2 Workshop on Smart Cities

posted Apr 6, 2017, 9:23 AM by Tobias Hoßfeld   [ updated Jun 6, 2017, 3:11 PM ]

The ITG FA 5.2 Workshop on Smart Cities is co-located with “Zukunft der Netze (ZdN)”, 28. - 29. September 2017, Lübeck. Smart Cities is an important application for Internet of Things technologies. Of major interest of this workshop are the communication networking and communication technology required. We are looking for proposals for presentations by the members as well as proposals for invited talks which are related to smart city communication and Internet of Things technologies. For the proposal, a title and short abstract of the presentation (about 250 words) is required. Please send your proposals via email to the workshop organizers until July 1st 2017.

ITC 28 in Würzburg

posted Dec 18, 2015, 4:59 AM by Tobias Hoßfeld   [ updated Dec 18, 2015, 5:00 AM ]

The evolution of communications and networking is changing the world we are living in. The digital connected world is triggered by the influence of computer science on telecommunication, the advent of the Internet and the massive deployment of mobile communications and optics, the appearance of collaborative networking and social networks, the ever-increasing speed and flexibility of new communication technologies, networks, user devices, and applications, and the ever-changing operational challenges arising from this development.

ITC 28 solicits original contributions that address the latest changes and developments in design, modelling, measurement, and performance evaluation of communication systems, networks, and services. ITC 28 is structured into eight different areas. The objectives in these areas include, among others, energy-efficiency and green IT, network security and privacy, QoS and QoE, and resilience.

We are happy that Nikhil Jain (Qualcomm Technologies) will give a keynote talk on Internet of Everything: Engineering Challenges and Opportunities.

Area 1: Smart cities and IoT (Alberto Leon-Garcia, Yanmin Zhu)
Area 2: Cloud services and networking (Arup Acharya, Patrick Lee)
Area 3: Mobile, wireless and 5G (Kin Leung, Thomas Hou)
Area 4: Next generation and future Internet architectures (Michael Zink, Thomas Zinner)
Area 5: Network and traffic management (Florin Ciucu, Peter Reichl)
Area 6: Network design and optimization (Thomas Bauschert, Eric Wong)
Area 7: Network measurements and analysis (Marco Mellia, Mark Squillante)
Area 8: Networked applications (Zhu Li, Lea Skorin-Kapov)

In addition, there will be a demo session across the areas.
Demonstration Session (Mark Berman, Michael Jarschel, Rick McGeer)

The conference takes place in the computer science building on the Hubland Campus of the University of Würzburg. The social event will be on Wednesday in the historical Würzburg residence. 

The submission deadline is March 4th, 2016. More information is online at

Special Issue of Computer Networks on “Traffic and Performance in the Big Data Era”

posted Jul 30, 2015, 11:12 AM by Tobias Hoßfeld   [ updated Jul 30, 2015, 11:13 AM ]

The 27th ITC in Ghent 2015 is organizing a special 
issue of the journal Computer Networks on "Traffic and Performance in the Big Data Era". The SI will contain a selection of 3-4 papers from ITC 27 anpapers selected from an open call


With the emergence of the Internet of Things, the number of devices being connected to the Internet is steadily growing and huge amounts of data are being generated worldwide. Big data brings new traffic and performance related challenges and calls for a deep revisit of the methodological tools that were traditionally used for performance evaluation and traffic engineering. New models and approaches are needed to investigate big data characteristics in terms of volume, velocity and variability and their impact on network performance; new solutions have to be designed to efficiently and securely manage information; new techniques are needed to support all phases of network planning, design and optimization. The scope of this Special Issue of Computer Networks reflects these challenges aiming at providing innovative contributions in this field. In the context of big data, we are interested in new methodologies and mode ling techniques, as well as new solutions; topics of interest include but are not limited to:
  • Traffic measurement, network planning and management in the Big Data Era
  • Impact of the Internet of Things- Use of Software-Defined Networking for the Big Data challenges
  • Big Data traffic modeling and management- Simulation methods and tools
  • Pricing, billing and business models
  • Traffic and performance monitoring in the Big Data environment
  • Anomaly and DoS attack detection
  • Privacy and trust
Schedule
  • Submission deadline: September 30th, 2015

  • Author notification: January 15th, 2015

  • Revised paper due: February 15th, 2016
  • Final author notification: April 1st, 2016
  • Publication: mid 2016
Guest-editors are the TPC co-chairs from ITC 27
  • Sabine Wittevrongel (Ghent University, Belgium)
  • Michela Meo (Politecnico di Torino, Italy)
  • Catherine Rosenberg (University of Waterloo, Canada)
