Abstract EN
A cognitive radio network with classified Secondary Users (SUs) is considered.
There are two types of SU packets, namely, SU1 packets and SU2 packets, in the system.
The SU1 packets have higher priority than the SU2 packets.
Considering the diversity of the SU packets and the real-time need of the interrupted SU packets, a novel spectrum allocation strategy with classified SUs and impatient packets is proposed.
Based on the number of PU packets, SU1 packets, and SU2 packets in the system, by modeling the queue dynamics of the networks users as a three-dimensional discrete-time Markov chain, the transition probability matrix of the Markov chain is given.
Then with the steady-state analysis, some important performance measures of the SU2 packets are derived to show the system performance with numerical results.
Specially, in order to optimize the system actions of the SU2 packets, the individually optimal strategy and the socially optimal strategy for the SU2 packets are demonstrated.
Finally, a pricing mechanism is provided to oblige the SU2 packets to follow the socially optimal strategy.
