Current research and development works have created a new concept in information and communication technologies: Internet of Things (IoT). IoT is a network of interconnected objects based on standard communication protocols. Today's wireless networks arc characterized by a fixed spectrum assignment policy. In accordance with country policies and existing laws, wireless networks are configured to use the assigned frequency band. The limited available spectrum and inefficiency of spectrum utilization have created the paradigm of opportunistic spectrum idles in existing wireless networks. This new network paradigm has been called "x New Generation Networks (xG Networks)", "Dynamic Spectrum Access (DSA)" and "Cognitive Radio Networks (CRN)". The Internet of cognitive radio-based objects incorporates new methods in order to solve some problems such as spectrum usage, bandwidth and usage area of the objects using the internet, using the characteristics of cognitive radio networks. In this study, routing algorithms, which can be used for Cognitive Radio Based IoT objects, will be examined by considering channel switching cost, end to end delay cost, energy efficiency and bandwidth dependent cost.
