Dynamic spectrum access techniques are proposed to solve the limited available spectrum and inefficient spectrum utilization problems. The key technology for dynamic spectrum access techniques is cognitive radio networks. Cognitive Radio Sensor Network (CRSN) is a recently emerging paradigm that aims to utilize the unique features provided by CR concept to incorporate additional capabilities to Wireless Sensor Network (WSN). The realization of CRSN depends on addressing many difficult challenges, posed by the unique characteristics of both cognitive radio and sensor networks and further amplified by their union.
