SODiCS on Challenged Communication Environment

Through we experienced at the Eastern Japan Great Earthquake on March 11, 2011, a disaster information gathering systems are strongly needed to widely collect the disaster state around the evaluated areas, correctly analyze the degree of damages and quickly make decision of disaster recovery response. For this requirement, a mobile video surveillance system on a vehicle based on wireless network is useful on because of its wide rage monitoring and mobility. However, since most of the communication lines and systems are seriously damaged and the communication state is widely worse particularly in hilly and mountainous areas. In this paper, we introduce SODiCS (Spatial and Temporal Omnidirectional Video Distribution and Collection System) for challenged communication environment. Video data gathered using omnidirectional camera and various sensors are transmitted to all of the users through a web application. The user can see those collected data on GIS map as a web application. We developed the system with two modes as video distribution functions, Live View mode and Storage View mode. The system configuration and architecture are explained and a prototype system is constructed to evaluate the performance of our system.
