Spectrum Allocation Method Based on Modified Social Spider Optimization Algorithm

In this paper, modified social spider optimization algorithm (MSSO) has been proposed to solve the spectrum allocation problem in Macrocell/Femtocell heterogeneous network. As an integer programming problem, existing intelligence algorithms show some disadvantages in the convergence rate and accuracy in such spectrum allocation task in heterogeneous network. Besides we consider the user demand satisfaction rate when modeling the system throughput. From the simulation results, MSSO has excellent optimization performance for high-dimensional integer programming problems.
