Figure 1From: Probabilistic framework for opportunistic spectrum management in cognitive ad hoc networksExample problematic scenarios. The primary network transmission will be intercepted by the secondary transmission initiated due to a miss-predicted spectral opportunity as shown in Figure 1a. Meanwhile, the secondary user misses a spectral opportunity because of the misleading interference measurement as depicted in Figure 1b. a Hidden primary sender scenario; b Exposed primary sender scenario.Back to article page
