This paper describes a semantic modeling of the sensor data streams. In order to fulfill the requirements of the Wireless Sensor Networks and Wireless Body Area Networks data streams, for real-time vital signs monitoring, we designed a flexible architecture based on Multi-agent system. The system is able to collect and build sensor data streams according to the proposed semantic model. Different data attributes are presented in order to describe timestamp, vital signs, values, etc., for each reading. The system can handle the large amount of sensed physiological data from different sensor nodes and to transmit only average values for a specific time series reducing unnecessary transmissions and energy consumption.
