Prioritized Access in a Channel-Hopping Cognitive Network with Spectrum Sensing

We investigate the performance of priority-based access in a channel-hopping cognitive network, in particular the interaction between the number of packets each node is allowed to send in a single transmission cycle and the penalty coefficient that determines the amount of sensing to be done upon a successful transmission. Our results indicate that giving higher bandwidth allocation to low priority traffic class improves the performance of the network without affecting the performance for high priority class traffic.
