    Spectrum Allocation for Cognitive Radio Networks Using the Fireworks Algorithm

    Zhou Feng, Xue Weilian*

    Computer Systems Science and Engineering, Vol.33, No.4, pp. 275-286, 2018, DOI:10.32604/csse.2018.33.275

    Abstract The fireworks algorithm features a small number of parameters, remarkable optimization ability, and resistance to a local optimum. Based on the graph coloring model, the fireworks algorithm is introduced for the first time to solve the spectrum allocation problem for cognitive radio networks, thus maximizing utility and fairness of spectrum allocation. Two-layer binary coding is adopted for individual fireworks. The first layer refers to the coding of cognitive users used to determine channels that can be connected with the user. The second layer refers to the auxiliary coding of channels responsible for addressing mutual interference More >
