Abstract:
Cognitive Wireless Sensor Networks are an emerging technology with a vast potential to avoid traditional wireless problems such as reliability, interferences and spectrum scarcity. Cognitive Wireless Sensor Networks frameworks are a key issue in the future developments of these networks because they allow a lot of protocols, strategies and optimization algorithms to be tested. A framework composed of a network simulator based on Castalia is presented in this paper. This simulator has been improved with cognitive features and feedback from Cognitive Wireless Sensor Networks real devices. This framework allows an easy and intuitive development of complete cognitive networks with spectrum sensing, learning and collaboration features. This is a crucial issue in order to facilitate the design and development of new algorithms, strategies and protocols for Cognitive Wireless Sensor Networks, and evaluate their performance. The benefits of the proposed framework are demonstrated with four different scenarios and simple cognitive communications strategies. Results show how new concepts have been successfully integrated in the framework and how several areas of research could take advantage of it.
