| Abstract | Cognitive Radio Sensor Network is a recently emerging paradigm that aims to utilize the unique features provided by the Cognitive Radio concept to incorporate additional capabilities in existing Wireless Sensor Networks. Wireless sensor networks operate in licensed bands. Due to tremendous growth in other band technologies, namely Bluetooth, , , and so on, wireless sensor networks need additional capabilities to combat the interference caused by them. Usage of opportunistic spectrum access capability offered by Cognitive Radio technology can be the optimal approach to address this issue. However, adoption of cognitive radio concepts in wireless sensor networks can impose added challenges and requirements. In this chapter, a comprehensive survey oF challenges, requirements, and applications of cognitive radio sensor networks is presented. Further, the node level and network level modifications made in the architecture of wireless sensor networks is also detailed in order to provide understanding of spectrum management and power optimization in cognitive radio sensor networks.Cognitive Radio Sensor Network (CRSN) is an emerging paradigm that aims to utilize the unique features provided by the Cognitive Radio (CR) concept to incorporate additional capabilities in existing Wireless Sensor Networks (WSN). A WSN is a wireless network created with a large number of nodes which possess the capabilities of sensing, processing, and communicating. These nodes are normally battery operated, hence low power wireless communication is adopted. The chapter presents a comprehensive survey of challenges, requirements, and applications of CRSN. It shows the wireless communication architecture of a CRSN. The chapter consists of Primary user (PU) and the Secondary user, also known as the cognitive sensor node (CSN). The PU is served by the primary Base station. The CSN is classified into conventional, mobile, and high power. The chapter considers the function of each communication layer, which includes physical, data link, network, transport layer, and application layers. It discusses significance of dynamic spectrum management. |
