Abstract(in English) In a wireless sensor network used as a social infrastructure, priority control is essential to prefer transmission of urgent information over other non-urgent information. In our previous report, we proposed UMIUSI (aUtonomous Mechanisms Integrated for Urgent Sensor Information) architecture, in which several simple mechanisms are combined to enable autonomous and distributed traffic control while adapting to the scale of an emergency. In this paper, we conducted practical experiments in two testbeds with off-the-shelf sensor nodes onto which we implemented UMIUSI, and evaluated the delay and loss rate of urgent information. The results showed that UMIUSI improved the reliability and latency of transmission of urgent information regardless of the scale of an emergency.
