New Challenges Implementing Cognitive Radio in Wireless Sensor Networks: A Survey

Abstract

With the growing demand of wireless applications, radio spectrum has become a scare resource. Cognitive Radio (CR) technology has been considered as an important solution to optimize the utilization of natural frequency spectrum. Numerous researches are performed on deploying CR in cellular networks. In this paper, we introduced new challenges on integration of CR technology and Wireless Sensor Networks (WSN), and some potential solutions are proposed.
