The Applications in Channel Assignment Based on Cooperative Hybrid Artificial Bee Colony Algorithm

The frequency resources of mobile communication network are limited. In order to improve utilization of wireless resource, we used the cooperative hybrid artificial bee colony algorithm to solve the wireless channel assignment problem. The proposed algorithm used the dynamic step to balance local and global search capability, the dynamic step was cosine rule with the increasing times of iteration; The artificial bee colony were divided into two subgroups with different evolutionary strategy co-evolution, the algorithm was easy to jump out of local optimal solution in this way; The introduction of the single-individual selective mutation increased diversity of population and the speed of convergence. Simulation results show that: the proposed algorithm can be better to solve the wireless channel assignment.
