摘要：In this paper we propose the design of a wearable embedded system1 for wirelessly
delimiting an hazardous area during emergency, alerting the rescue operators when entering in
it and measuring the consequent exposition time. (The dangerous area is previously identified,
e.g., through suitable instrumentation). The suggested approach, which is identically effective
in indoor and outdoor environments, significantly extends existing solutions by not requiring
any absolute position information for delimiting the hazardous area or fixed infrastructure as
requested instead by GPS and UWB solutions. The proposed low-power system can be easily
retrieved after use and ready to be deployed in a new environment.
