Abstract :
In this paper, a design for a cognitive MAC protocol based on Primary User (PU) feedback exploitation is proposed. A queuing approach is adopted and an infinite-state Partially Observable Markov Decision Process (POMDP) framework is proposed where the states represent the number of packets in the primary queue. The primary user quality of service (QoS) guarantee is defined through a primary queue stability constraint. Finally, we propose a greedy algorithm to simplify the design of the MAC protocol. Existing techniques and results for POMDP can then be used to develop MAC protocols.
