Popis: | limited spectrum resources and interferences are the fundamental challenges in Cognitive Radio Networks (CRN). With the increasing demand for spectrum with the evolution of wireless technologies, an efficient assignment of these resources that avoid the interference in an allocation’s plan becomes critical. In this paper, we propose a new efficient hybrid meta-heuristic which intents to assign the appropriate channel to the secondary users (SUs) in terms of its requirement without causing interference with the primary users (PUs) or other SUs (which use the same channel simultaney). Our proposition combines the Gray Wolf optimizer approach (GWO) with the Tabu Search (TS). The experiment results show a clear improvement in our proposal compared to the application of GWO without TS. |
