              Workshop on Ultra Wide Band for Sensor Networks

                              Call For Papers

   Ultra Wide Band radio is, in principle, a physical transmission
   technique suitable for all kinds of applications. Given the strong
   power emission constraints imposed by the regulatory bodies in the
   United States -- but likely to be adopted by other countries as well
   -- UWB is emerging as a particularly appealing transmission technique
   for applications requiring either high bit rates over short ranges or
   low bit rates over medium to long ranges.

   A recent release of the IEEE 802.15.4 standard for low-rate WPANs has
   increased attention for the low-bit-rate case. The low-bit-rate,
   medium- to long-range case applies to long-range sensor networks such
   as indoor-outdoor distributed surveillance systems; nonreal-time data
   applications like e-mail and instant messaging; and in general all
   data transfers compatible with a transmission rate in the order of 1
   Mbit/second over several tens of meters.

   The scenarios of applications mentioned above refer to networks that
   commonly adopt the self-organizing principle -- that is, distributed
   networks. Examples of these networks are ad hoc and sensor networks,
   such as groups of wireless terminals located in a limited-size
   geographical area, communicating in an infrastructure-free fashion,
   and without any central coordinating unit or base station.
   Communication routes may be formed by multiple hops to extend
   coverage.

   Ultra Wide Band's typical features, such as the need for operating at
   low power vs. a rather accurate ranging capability, may have a
   significant impact on the design of the MAC and of routing algorithms
   and strategies. The optimization of MAC and network modules in ad hoc
   networks is a topic that currently occupies research attention
   worldwide.

   The impulse-radio (IR) principle, in particular, may boost innovation
   in designing efficient algorithms for resource sharing and management
   because of the impulsive nature of the transmission. IR intrinsically
   partitions time in a peculiar way, because of the short and limited
   duration of the pulses. The spectrum of the IR signal is usually
   shaped by encoding data symbols using time-hopping pseudorandom
   sequences that may also serve as users' signatures, and ensuring
   access to the medium by multiple users. This resource-partitioning
   scheme is called time-hopping multiple access (THMA).

   MUI in continuous-transmission vs. IR systems may substantially differ
   in nature, especially when in IR the number of pulses in the air is
   not sufficiently large to fill up the time dimension. Examples of
   those application scenarios are sensor networks that are typically
   characterized by low data rates and sparse topologies.


   Authors are invited to submit original contributions on topics
   following in the above context. In particular topics of interest
   include (but are not limited to):


     * Transceiver architectures for UWB sensor nodes
     * Indoor and outdoor UWB channel modelling
     * Synchronization issues for low-rate UWB communications
     * Algorithms for sensor localization and tracking
     * Mobility models for networks of mobile sensors
     * Cross-layer design techniques
     * Distributed power control mechanisms
     * Distributed algorithms for resource management
     * Distributed topology control mechanisms
     * Methods and algorithms for hierarchical clustering
     * Energy-aware MAC and routing protocols
     * Location-aware MAC and routing protocols
     * Support of Quality of Service in UWB sensor networks
     * Simulation and Modelling of UWB sensor networks

   All accepted papers will be published in the proceedings of the
   workshop. Selected papers will be considered for publication in the
   Journal of Mobile Networks and Applications (MONET), published by
   Kluwer Academic Publishers.
