Tracking and physical condition monitoring of people who find themselves in hazardous situations, and therefore may require special attention, is crucial to improving their safety. The systems that are commonly used for this purpose do not include individual monitoring or are too expensive and intrusive to be deployed in common situations. In this project, a system based on energy-efficient Wireless Sensor Networks and RFID has been developed to achieve the positioning and monitoring of people in hazardous situations. The system that has been designed is capable of identifying each individual, locating him or her, send data regarding their physical situation and ascertain whether they are located in an open or closed space. Furthermore, in emergency situations such as a fall or loss of consciousness, the system is also capable of triggering the corresponding alarm. The results show that the use of this system allows us to find out the location and state of a person, as well as providing an analysis of the potential risks at each moment, in real time and in an energy-efficient way. In an emergency, the system also allows for a quicker intervention, as it not only provides the location and causes of the event, but also informs about the physical condition of the individual at that moment.

Epidemic-based routing algorithms have some redundancy in the process of packets exchange and sensing neighbor. To address this problem, a low-delay routing algorithm of Delay-Tolerated Network based on packet exchange, PEA (Packet exchange algorithm), was proposed in this *** algorithm firstly sent data packet when nodes sensed encountered node, broadcast SV packets to speed sensing neighbor and decrease end-to-end delay. Theoretical analysis and simulation results show that PEA outperforms the classical Epidemic routing algorithm in terms of end-to-end delay, the total time of data delivery.
