********************************************************************** Call for Workshop Proposals Sixth International Conference on Networked Sensing Systems (INSS 2009) June 17-19, 2009 Carnegie Mellon University Pittsburgh, PA, USA http://www.inss-conf.org/ Sponsored by TRF, IEEE ********************************************************************** We invite proposals for the workshop program of INSS 2009, the Sixth International Conference on Networked Sensing Systems to be held in Pittsburgh at Carnegie Mellon University. During the past years, INSS has established itself as THE scientific event where academic and industrial experts from the areas of sensor systems, wireless networks, and sensor network applications come together. Workshops provide a lively forum for experts from both academia and industry to discuss and exchange the latest topics in these areas. The topics may focus on any aspect of the research field: new and emerging research directions, novel and highly innovative themes, real-world topics including industrial deployments and applications, and interdisciplinary themes. The goal of the workshops is to share insights and experiences, to foster research communities and to fertilize collaborations between the experts from both science and industry. Workshops are a unique platform for opportunities to extend topics beyond the scope of the main conference and to pave the roads for future directions in order to facilitate the accelerating progress in networked sensing systems. Workshops will be typically full day or half day. The workshop organization will be also prepared for very practical workshops including live demonstration and experiments with networked sensing systems and will try for best provision of an appropriate infrastructure support. Important Dates --------------- For workshop proposals: Submission Deadline (workshop proposals): January 20, 2009 Acceptance Notification (workshop proposals): January 27, 2009 Workshop Announcement: February 1, 2009 For workshop papers (preliminary recommendations): Submission Deadline: March 1, 2009 Workshops: June 19, 2009 Proposal Content ---------------- We solicit workshops in all areas related to networked sensing systems. In particular, we would like to encourage proposals for workshops, which act as a melting pot for the research effort on novel and innovative topics. We encourage having an international team of organizers and teams with experts from academia and industry. Organizers are expected to be active themselves in the field where they propose a workshop. All proposals should be submitted by electronic mail to the workshop chair in pdf format. The recommended length of the workshop proposal is 2 pages, and should include: - Title of the workshop. - Brief technical abstract of the workshop, identification of specific technical issues, focus, and justification of its timeliness. - Longer description on the format, activities, goals and outcomes. Please indicate the planning of demos, posters, discussion groups, etc. - A brief description of the review process. - The names, affiliations and e-mail addresses of the proposed workshop organizing committee. This committee should consist of at least two persons knowledgeable in the proposed topic. - The names, affiliations and e-mail addresses of a preliminary workshop program committee. - Primary contact of the organizing committee. - Estimated number of participants, length, and timetable of the workshop.
