In this paper, we presented a priority aware MAC Protocol for delay-bounded applications, which is called PA-MAC.The PA-MAC protocol was designed for some applications such as field monitoring in which both abnormal data and normal data may be collected.In this kind of WSNs applications, sensor nodes may need to send both abnormal data and normal data.Abnormal data packet may be generated when there is an event such as exceeding threshold value or object appearance.These events are generally critical, so the collected abnormal data should be transmitted in limited time to their final destination node faster than the normal data.Therefore, the priority packet transmission mechanism is necessary in these applications.Experiment results show that the PA-MAC protocol reduces entire packet transmission delay and average node energy consumption in comparison to existing related MAC protocols.
