Abstract:
In this paper, a novel spectrum handoff scheme for cognitive ultra-wide band industrial networks (CUWBINs) is proposed, where secondary users (SUs) can access the licensed channels despite the present of primary users' signals. To maintain continuous connectivity between the cognitive users, licensed channels can be opportunistically used by an SU as long as its transmission does not interfere with PUs. According to simulation results, the proposed spectrum handoff algorithm significantly outstrips the existing random sensing based spectrum handoff scheme in terms of spectrum efficiency and switching-handoff delay.
