Reactive spectrum handoff combined with random target channel selection in cognitive radio networks with prioritized secondary users
Cognitive radio aims at improving spectrum utilization by allowing secondary users to access primary user’s spectrum. The delay time of secondary users due to multiple interruptions from primary users is considered a crucial issue. In this work, to reduce secondary user delay time, we propose a mixe...
