Abstract

In this work, a hybrid RF/FSO system employing a game theoretic spectrum trading process is investigated. Different from the hybrid systems in the literature, in the proposed system no RF spectrum is preallocated to the FSO link. Only under infrequent adverse weather conditions where the availability of the FSO link is severely impaired, the source borrows a portion of the licensed RF spectrum from the surrounding RF nodes. The competition among RF nodes is considered and the Stackelberg game is employed to model the spectrum trading game between the source of FSO link and the RF nodes. Using the leased spectrum, the source can establish a hybrid link containing not only the original FSO link but also an RF link to improve its throughout to the destination. Our performance analysis demonstrates that the proposed scheme improves the average capacity of the system in adverse weather conditions remarkably, thereby enhancing the availability of FSO communications.
