The summary of the domains of activity of this group are:
Live video streaming over Internet has attracted much attention nowadays and many mechanisms have been introduced to tackle challenges behind this applications. Recently streaming over peer to peer overlay networks is proposed as an scheme to build scalable video stream applications. This group in DML is aiming to inspect this field using peer to peer approaches. DML’s peer to peer streaming group main goal is to study peer to peer overlay networks and their potentials for streaming applications.
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. We are building a WMSN Lab to experiment with multimedia applications in sensor architectures. Frame manipulation is required to minimize the amount of data to be sent. We are also defining and evaluating network protocols for WMSN taking into account traffic characteristics and error control mechanisms.
