    Resource Allocation with MAC Layer Node Cooperation in Cognitive Radio Networks by Andreas Merentitis, Dionysia Triantafyllopoulou

    Published 2010-01-01
    “…The proposed algorithm utilizes Medium Access Control layer mechanisms for message exchange between secondary nodes that operate in license exempt spectrum bands, in order to achieve interference mitigation. A fuzzy logic reasoner is utilized in order to take into account the effect of the coexistence of a large number of users in the interference as well as to cope for uncertainties in the message exchange, caused by the nodes' mobility and the large delays in the updating of the necessary information. …”
