摘要
In this paper,a novel WLAN system,Cognitive WLAN over Fiber (CWLANoF),is introduced in the first place.Moreover,when CWLANoF has more channels than STAs,a new channel allocation scheme is proposed using the Hungarian algorithm,which is demonstrated to be the optimal one.Furthermore,when CWLANoF has fewer channels than STAs,it is possible for more than one STA to share the same channel simultaneously based on the new features of CWLANoF.And the power control scheme is proposed for this kind of sharing,considering efficiency and fairness.Finally,extensive simulation results illustrate the significant performance improvement of the proposed channel allocation scheme and power control scheme.

Moreover, when CWLANoF has more channels than STAs, a new channel allocation scheme is proposed using the Hungarian algorithm, which is demonstrated to be the optimal one. Furtheimore, when CW- LANoF has fewer channels than STAs, it is possible for more than one STA to share the same channel simulta- neously based on the new features of CWLANoF. And the power control scheme is proposed for this kind of sha- ring, considering efficiency and fairness. Finally, extensive simulation results illustrate the significant performance improvement of the proposed channel allocation scheme and power control scheme.
