An Emergency Search and Rescue System Based on WSN and Mobile Robot

In this paper we provide a brief introduction to the CAESRS (chemical accident emergency search and rescue system) project which is oriented to monitoring the leakage of hazardous chemicals and to guaranteeing the safety of people in hazardous areas. Technologies such as WSN (wireless sensor network) and mobile robot need to be integrated to build up CAESRS. We propose a system architecture that provides the framework for integration of the technologies. We describe the components of the generic CAESRS´s architecture in detail. Finally we present a small-scale demonstration experiment which has been completed to highlight the concept and application of the CAESRS to an actual chemical accident. Although our proposed system architecture provides a versatile framework for integration, a number of new and interesting research problems need to be solved before actual deployment of the system. We outline some of the future work in the last part of the paper.
