                  PRELIMINARY ANNOUNCEMENT and CALL FOR PAPERS

                                Mobiquitous 2004
       The First Annual International Conference on Mobile and Ubiquitous
                        Systems: Networking and Services
                August 22-25, 2004 - Boston, Massachusetts, USA

                           (ACM sponsorship pending)


   The combination of mobile and ubiquitous computing is emerging as a
   promising new paradigm with the goal to provide computing and
   communication services all the time, everywhere, transparently and
   invisibly to the user, using devices embedded in the surrounding physical
   environment. In this context, the communication devices, the objects with
   which they interact, or both may be mobile. The implementation of such a
   paradigm requires advances in wireless network technologies and devices,
   development of infrastructures supporting cognitive environments, and
   discovery and identification of ubiquitous computing applications and
   services. The first ACM Annual International Conference on Mobile and
   Ubiquitous Systems: networking and services (Mobiquitous 04) will cover
   all these aspects, representing a forum where practitioners and
   researchers coming from the many areas involved in ubiquitous solutions
   design and deployment will be able to interact exchanging the cross-layer
   experiences needed to build the overall ubiquitous systems. Areas
   addressed by the conference include: applications, service-oriented
   computing, middleware, networking, agents, knowledge management and
   databases.

   PAPERS:
   Technical papers describing original, previously unpublished research, not
   currently under review by another conference or journal, are solicited.
   The conference is interested in contributions addressing all the areas
   associated with mobile and ubiquitous architectures, infrastructure and
   services. Technical works clearly identifying how the specific
   contributions fit to an overall working solution are particularly of
   interest. Topics include, but are not limited to, the following feature
   topics:

     * Ubiquitous architectures and systems
     * Wearable computing and personal area network
     * Wireless technologies for mobile and ubiquitous communications
       (Bluetooth, ZigBee, 802.15.x, WiFi)
     * Wireless Internet access in ubiquitous systems
     * Reconfigurability and personalization of wireless network
     * Service discovery mechanisms, knowledge discovery, matching and
       composition mechanisms
     * Wireless/mobile service management and delivery
     * Security, privacy and social issues of mobile and ubiquitous systems
     * Peer-to-peer knowledge management
     * Emerging industrial/business scenarios
     * Multimodal interfaces (speech, video kinetic, tactile)
     * Smart spaces
     * Ad hoc and sensor networking
     * Localization and tracking
     * Context and location aware application
     * Multimedia encoding and transcoding
     * Middleware services
     * Agent technologies in ubiquitous, wearable, and mobile systems
     * Hardware and software platforms for ubiquitous systems, and testbeds
     * User interfaces
     * Toolkits, development environments, and languages for ubiquitous
       computing
     * Ontologies for mobile and ubiquitous computing

   SUBMISSION INSTRUCTIONS:
   All paper submissions will be handled electronically (see the conference
   web page for details). Authors should prepare a Portable Document Format
   (PDF) or postscript version of their full paper. Papers must not exceed 8
   pages double column (US Letter size, 8.5 x 11 inches) including text,
   figures and references. The font size must be at least 10 points.

   PUBLICATION:
   All submitted papers will be rigorously reviewed by technical program
   committee members. Accepted papers will be published in the conference
   proceedings. Papers of particular merit will be proposed for publication
   in the ACM/Kluwer Wireless Networks journal.

   TUTORIALS:
   Proposals for tutorials are solicited. Evaluation of tutorial proposals
   will be based on the expertise and experience of the instructors, and on
   the relevance of the subject matter. Potential instructors are requested
   to submit a tutorial proposal of at most 5 pages, including a biographical
   sketch, to the Tutorial Chair by March 1, 2004.

   DEMOS:
   Proposals for research and industrial demos are solicited. A maximum of 3
   pages should be submitted which include a description of the demo and
   needed equipment. Proposals should be submitted to the Demo Chair, which
   will be announced shortly.
