CR simulator: A Wireless System for IOT

Proliferation of wireless systems increases the need for more radio spectrum band which unfortunately is not available. Radio spectrum is fully allocated for different services, applications and users, observation showed that not al the allocated spectrum is completely utilized. By the evolution of cognitive radio concept, spectrum utilization can be improved. The Internet of Things, fast-emerging ecosystem of intercommunicating devices is proliferating rapidly. Current research on Internet of Things (IoT) mainly focuses on sensing general objects of the physical world and make them connected sharing their observations. In this paper, a cognitive radio network based system is proposed and how they provide Internet of things a perceptive network condition. The system can analyze the perceived knowledge, perform adaptive actions, and make intelligent decisions which aim to maximize network performance.
