A Priority based Media Access Protocol for Event-driven Wireless Sensor Networks |
|
|
Wireless sensor networks can be used to detect and report emergency situations (e.g. bush fires) based on temperature change, object movement etc. The problem is that many neighbouring sensors may detect and then try to send the same signal during an emergency, causing network congestion, data delay and data loss. We proposes a priority based medium access protocol which allows the sensor with the most urgent signal (e.g. highest temperature reading) to transmit the signal with highest priority and minimum delay. The simulation results show that the proposed protocol outperforms the conventional medium access control protocol in terms of end-to-end network delay and packet loss. |
