[We apologize in advance if you receive multiple copies of this CFP.] _____________________________________________________________________ _____________________________________________________________________ Call for Papers COMPUTER NETWORKS JOURNAL (ELSEVIER) Special Issue on WIRELESS MULTIMEDIA SENSOR NETWORKS Submission deadline: April 30, 2007 _____________________________________________________________________ _____________________________________________________________________ Wireless Sensor Networks (WSN) have recently been the focus of a significant amount of attention and effort of the research community. The main motivation has been to address the challenges posed by the WSN paradigm, i.e., limited node power, processing, and communication capabilities, dense network deployment, multi-hop communications, and heterogeneous application-specific requirements. The vast majority of these studies applies to conventional WSN applications which need reliable and efficient communication of scalar event features and sensor data such as temperature, pressure, humidity. With the availability of low-cost small-scale imaging sensors, CMOS cameras, microphones, which may ubiquitously capture multimedia content from the field, Wireless Multimedia Sensor Networks (WMSN) have been proposed and drawn the immediate attention of the research community. WMSN applications, e.g., multimedia surveillance networks, target tracking, environmental monitoring, and traffic management systems, require effective harvesting and communication of event features in the form of multimedia such as audio, image, and video. To this end, additional challenges for energy-efficient multimedia processing and communication in WMSN, i.e., heterogeneous multimedia reliability definitions, tight QoS expectations, and high bandwidth demands, must be addressed as well. This special issue solicits papers describing the state-of-the-art, reliable and efficient multimedia processing and delivery solutions imperative for the realization of WMSN. Original contributions (previously unpublished and not currently under review) are solicited in areas including (but not limited to) the following: * Novel WMSN architectures and applications * Protocols for real-time, reliable multimedia streaming in WMSN * Energy-efficient MAC, routing, and traffic management for WMSN * Cross-layer design for effective communications in WMSN * Low-bit rate and energy-efficient multimedia source coding for WMSN * Joint multimedia processing and communication solutions for WMSN * Distributed source coding and multimedia processing in WMSN * Information fusion and multimedia aggregation in WMSN * Group and cooperative communications for multimedia delivery in sensor/actor networks * WMSN capacity modeling and theoretical analysis * Delay-tolerant networking for WMSN * Topology control, localization, synchronization, and mobility * Physical layer technologies for efficient WMSN * Secure multimedia communications in WMSN * Experimental and testbed studies of WMSN Submission Instructions and Important Dates: ____________________________________________ Prospective Authors: Please follow Computer Networks (Elsevier) Journal format described at http://www.elsevier.com/locate/comnet, and submit your papers to the online submission and reviewing system at http://www.editorialmanager.com/comnet.
