A broadcast protocol in Multi-Hop Cognitive Radio Ad Hoc Networks with guarantees
Ιωάννα Κακάλου, Kostas E. Psannis · 2017
Cognitive Radio (CR) technology was introduced to answer the spectrum scarcity problem by enabling unlicensed users (secondary users) to access opportunistically the licensed spectrum bands, when the licensed users do not transmit. This paper work introduces a broadcast protocol for Multi Hop Ad Hoc Networks that organizes secondary users (SUs) in clusters in a distributed manner based on the locally available channels with a dynamically selected Common Control Channel (CCC) for the cluster's operation and reliable broadcast delivery. All broadcasting transmissions have guarantees for Collision Avoidance, low latency, no additional delay. To the best of our knowledge, there is no other work with such guarantees and bandwidth assurance provision. The clusters are self-organized such that they can be cloud-assisted on demand.
