Abstract :
The system of post-earthquake information rapid report can make people survive the aftershock, therefore the alarm of seismograph nodes in the system should be transferred as soon as possible. In this paper, a priority node MAC protocol for mobile ad hoc networks is proposed. The priority node token ring approach is used for the transmission of low delay information. By the embedded Markov chain method, the mean queue length of the high priority node and the general node are obtained, and verified by simulations. The delay performance was studied with simulations, the mean delay of the high priority node is less than the general node, and the high priority node owns low delay transmission even when traffic intensity is heavy. According to the total traffic delay, this protocol outperforms the CSMA priority MAC protocol, and our protocol keeps low delay of the high priority node and general node without dropping frames under the heave load. This feature is essential for earthquake surveillance.
