A Fast and Reliable Transmission Mechanism of Urgent Information in Sensor Networks
نویسندگان
چکیده
A fast and reliable transmission mechanism of urgent information is essential for establishing a wireless sensor network infrastructure for a safe and secure living environment. In this paper, we propose a transmission mechanism where high reliability and low latency in transmitting urgent information are achieved by making an “assured corridor” where urgent information is forwarded preferentially by suppressing emission of non-urgent information and keeping nodes in the corridor awake. Our mechanism avoids packet loss and possible delay caused by collisions in the wireless transmission and sleeping nodes. We verified our proposed mechanism through simulation experiments and showed that it drastically improved the reliability and the latency of the urgent information transmission.
