Abderrahim Benslimane is Full Professor of Computer Science and Engineering at the University of Avignon (France) since September 2001. He has been as Associate Professor at the University of Technology of Belfort-Montbéliard since September 1994. He obtained the title to supervise researches (HDR 2000) from the University of Cergy-Pontoise, France. He received the PhD degree (1993), DEA (MS 1989) from the Franche-Comte University of Besançon, and BS (1987) from the University of Nancy, all in Computer Science. His research and teaching interests are in wireless ad-hoc and sensor networks. Particularly, he works on multicast routing, inter-vehicular communications, Quality of service, energy conservation, localization, Security intrusion detection and MAC layer performance evaluation. He has several refereed international publications (book, journals and conferences) in all those domains. He serves as associate editor of many journals and technical program chair and co-chair, member of a number of international conferences. He has been reviewer of a great number of journals, of national research projects sponsored by the ANR/Telecom.

He is the header of Computer Networks and Multimedia Applications team of the Computer Laboratory of Avignon. He is involved in many national and international projects. He participates on the steering and the program committee of many international conferences. He is IEEE senior member and member of the CA and VP of student activities of the IEEE French Section/Region 8 and of the Technical Committee IEEE ComSoc Communications and Information Security (CISTC). He was from September 2005 to September 2006 in sabbatical year for research at the Mobile Computing and Networking Research Laboratory, Department of Computer Science, Ecole Polytecnique de Montréal.

Dr. Guenter Schaefer is Full Professor of Telematics/Computer Networks at the Faculty of Computer Science and Automation of Technical University Ilmenau, Germany since 2005. Prior to that, he was working at the Telecommunication Networks Group of the Technical University Berlin, Germany, with his research interests lying in the areas of network security, mobile communications, high performance communications, active networks, and network management (2000-2005). Between February 1999 and July 2000, he was a postdoctoral researcher at the Département Informatique et Réseaux of the Ecole Nationale Supérieure des Télécommunications in Paris, France, mainly working in a research project investigating the performance of the new ATM adaptation layer type 2 in the access network of third generation mobile networks, and in addition following his interests in network security by co-operating with former colleagues on the subject of mobile IP security. From October 1994 to January 1999, he was a researcher at the Institute of Telematics of the University of Karlsruhe, where he also obtained his PhD. degree (Dr.-Ing.) as well as his Diploma in Computer Science (comparable to M.Sc.). Dr. Schaefer is co-author of more than 50 refereed articles and of 4 international patents. His research interests lie in the areas of network security, protection of communication infrastructures, security-aware engineering of networked information systems, innovative protocols and applications of mobile und ubiquitous systems, as well as peer-to-peer based support of multimedia streaming applications and network security management. Dr. Schaefer is member of the ACM, IEEE and German Computer Science Society (GI).
