재난현장정보의 효율적 수집과 활용을 위한 재난용 주파수자원의 최적 활용 방안에 관한 연구

초록

In this study, we analyze various wireless access technologies such as the channelized transmission technologies, controlled access technologies and random access technologies in order to utilize limited radio resources allocated to the disaster information gathering. In particular, in case of massive disaster, a large amount of various disaster information can be gathered from many different disaster sites. In such case, this information can not be gathered timely and collected due to the limited radio resource. Therefore, in this study, we analyze many candidate wireless access technologies based on many techno-economical criteria. Our analysis result shows that the polling based controlled access protocol is the most appropriate technology for efficient utilization of limited disaster radio resource.
