Designing a sensor network architecture for transmission of urgent sensor information

In wireless sensor networks used as a social infrastructure, urgent information, such as a fire alarm, is needed to be transmitted as fast and reliably as possible. In this paper, we propose design methodology for a sensor network which provides preferential control of urgent information over other non-urgent information. In our methodology, several simple mechanisms which function in different spatial and temporal levels are introduced on each node and they work autonomously and independently as a reaction to the surrounding situation. We also show an example of a network architecture designed following the methodology. Our simulation experiments showed that the architecture successfully improved the delivery ratio and delay of the urgent sensor information.
