Notification Protocol of Sensing Information in Cognitive Radio System

摘要：

In recent years, the cognitive radio (CR) has been receiving a great attention to overcome spectrum scarcity. Up to now, many authors have proposed CR core technologies such as protocols, spectrum sharing method and sensing techniques. In this paper, we focus on notification protocol to exchange sensing information in the network. Since every node in CR network should send its sensing results to the gathering center, it takes long time to complete the notification process. So, in this paper, we design new notification protocol to minimize the number of notifications. It operates dynamically in accordance with prior informed reporting data. We demonstrate its superiority by Monte Carlo simulation.
