Abstract: A method for generating a distributed channel hopping system in cognitive radio networks. The method includes: 1) providing a symmetric asynchronous CH system comprising n periodic CH sequences such that each period of a CH sequence comprises exactly L frames and each frame comprises n timeslots; 2) labelling the n periodic CH sequences in the constructed CH system; 3) hopping, by the CH sequence i, to the channel (lM+j mod N) in each timeslot tt,j,d ∈ Uij of the frame l; and 4) hopping, by the CH sequence i, to an arbitrary channel h∉ {0, 1, . . . , N−1} in each timeslot t∉ Zn\RoT(U, i) of the frame l.
