The aim of the workshop is to bring together researchers and practitioners, in the areas of verification, control, performance, Quality of Service and dependability evaluation and assessment, to discuss the state of the art for solving the challenges facing us today in various modern computer and communication systems in which functional and non functional properties are strongly mixed.
Thus, the main motivation for VECoS is to encourage the cross-fertilisation between verification and evaluation approaches, methods and techniques especially those based on the specification formalisms for concurrent systems (i.e. process algebras, transition systems, automata networks, Petri nets, rewrite logic... etc).
The International Workshop on Verification and Evaluation of Computer and Communication Systems (VECoS) continues its mission as one of the leading forum for the presentation of all aspects of verification, performance modelling and analysis of computer and communication systems. The first edition was held in Algiers, Algeria (2007). This year's edition is held in Leeds, United Kingdom.
VECoS offers a unique forum for researchers and practitioners from academia to share their expertise results and achievements in all areas of verification and performance evaluation of computer and communication systems including analytic modelling, simulation and measurements.
This year's programme consists of six regular paper sessions and four invited talks. Various topics are covered in the programme and include Petri nets, model checking, and wireless sensor networks.
These proceedings record the contributions from the invited speakers and from the technical sessions. We present four invited papers, nineteen technical papers, selected out of submissions from sixteen laboratories.
We have been delighted by the overwhelming response from the international community of computer and communication systems to our call for papers. The workshop attracted a large number of high quality papers from many countries. Once again we welcome back our colleagues from Tunisia, Morocco, Algeria, France, Italy, Canada, and the United Kingdom.
The programme committee includes researchers from forty laboratories. Each paper submitted was evaluated by at least three reviewers. After the evaluation, reports were returned to the programme committee for discussion and resolution of conflicts. Based on their recommendations, we implemented a consensus process, and selected the nineteen papers that we present here.
We are grateful to all members of the programme committee, the organising committee and to all referees for their hard work. The support and encouragement of the steering committee were invaluable assets. Without the support of our institutions, VECoS2008 could not have been a reality. Their recognition of the importance of this event is greatly appreciated. Finally, we would like to thank all the authors of the invited and submitted papers, and all participants at the Workshop. They are the main focus of VECoS.
We would also like to thank the School of Computing at the University of Leeds for hosting the event.
