CSCD: A simple channel scan protocol to discover and join a cognitive PAN

The paper describes a simple channel scan protocol through which a station can quickly discover and join an existing piconet following a specified channel-hopping MAC protocol piconet in its vicinity. The proposed MAC protocol is simple and does not need a dedicated control channel. Moreover, the cognitive piconet can operate normally throughout the search, unlike Bluetooth where piconet operation is temporarily suspended during the inquiry/inquiry scan procedure. The performance of the proposed protocol is evaluated through discrete event simulation.
