Design of a Safety Confirmation System Integrating Wireless Sensor Network and Smart Phones for Disaster

In these years, disasters often occurred in Japan and abroad. When the disaster happen, general communication methods, e.g., cell phone, may not work well due to the damage of communication infrastructure or restriction of usage of communication resources. How to let users quickly confirm safety is a critically important problem after a disaster. Therefore, we propose a design of safety confirmation system integrating WSN and smart phones. Users can input messages using smart phones and the messages are sent through WSN built based on sensor nodes mounted on smart phones. A preliminary simulation has been performed to evaluate the effectiveness of the method for transferring messages.
