Wireless Networked Omni-directional Video Distribution System Based on Delay Tolerant Network on Disaster Environment

摘要

In this paper, we introduce Wireless Networked Omni-directional video collect and distribution System for both normal and challenged network environment. Omni directional video camera is used to capture the 360 degree of surround image with various sensor including GPS location, 3-densional gyro-sensor, temperature sensor data. Those data are transmitted to all of the users through Web system. In normal network condition, the conventional IP protocol over mobile network or wireless network are used to access to Web server through Internet. The delay tolerant network protocol (DTN) is used between the vehicles and the web server to support challenged network environment such as mountain road and disaster area. The user can see the live video and recorded video along the road with 360 degree surround on GIS map as Web services. The system configuration and architecture are explained and a prototype system is constructed to evaluate the functional and performance. Through the performance evaluation, the usefulness and effects of the proposed system is validated.
