Cognitive radio routing in wireless sensor networks — A comprehensive study

Wireless Sensor Networks (WSNs) is a collection of small powered devices which have sensing and computation abilities along with wireless communications capabilities. In this article, how Cognitive Radio (CR) capability enhances the performance in WSN for wireless communications is discussed. A cognitive radio routing in WSN along with the algorithm is outlined based on comparative of various routing protocols in Cognitive Radio Sensor Networks (CRSN's) and their suitability to CR environment.
