Title: Architecture and Communication Protocol for CRN and A SDR-driven Service

Abstract:
In the recent times, we have experienced a rapid development in wireless technologies. This exceptional advancement has triggered an escalating demand for new radio spectrum. As a result, these technologies may suffer from the spectrum scarcity issue as spectrum is a finite precious natural resource and most of the spectrum bands have been allocated. Cognitive Radio Network (CRN), is expected to utilize radio spectrum efficiently and is also considered to be an intelligent and self-organized communication system that has the ability to adjust its functionality depending on the network environment. In this study, we discuss a cluster-based architecture for cognitive radio ad-hoc networks. We also discuss communication protocol on this architecture. Moreover, we show a software defined radio (SDR) driven cellular network system which can be deployed in a disaster-hit area to provide service to the affected population for free voice and message communication with the search and rescue (SAR) team members.
