A Multimedia Delivery System for Delay-/Disruption-Tolerant Networks

Christian Raffelsberger and Hermann Hellwagner (Alpen-Adria University of Klagenfurt)



Multimedia delivery systems and protocols usually assume end-to-end connections and low delivery delays between the multimedia source and consumers. However, neither of these two properties can always be achieved in hastily formed networks for emergency response operations. In particular, disruptions may break end-to-end connections which makes it impossible to deliver multimedia content instantly. This work presents a multimedia delivery system that can operate in disrupted networks and hence may help improve the situational awareness in emergency response operations. The multimedia delivery system is based on HTTP Adaptive Streaming (HAS) and uses a modified version of HTTP which is able to deliver data in partitioned networks. The multimedia delivery system is evaluated in a realistic emergency response scenario.
