Therefore, we propose a warning system model based on the
information from civilians with the emphasis of citizen
warning. This paper describes the suggestion of Community
Warning System Services under social networking where we
live in with many communication channels in section II. To
improve warning system in consider to the notification to
emergency service units and civilians, we applied SIP
technology into our system as describe in section III. In section
IV, we present our prototype of Community Warning System
Service while prototype testing and the results are in section V.
We conclude and discuss further development in section VI.
