Cognitive radio sensor networks in industrial applications

Abstract

This chapter explains the benefits of cognitive radio sensor networks (CRSN) in industrial applications and discusses the open research directions for this promising research area. It also discusses the CRSN architecture configurations in industrial applications. The chapter presents the algorithm needs of CRSN for spectrum management in industrial applications. It provides the open research issues on communication protocol development for CRSN in industrial applications. Minimization of environmental effects, adaptation to varying spectrum conditions, and overlay deployment of multiple sensor networks are some of the promising advantages of CRSN in industrial applications. However, the realization of CRSN in industrial applications mainly requires efficient spectrum management functionalities to dynamically manage the spectrum access of sensor nodes in challenging industrial communication environments. Requirements and research challenges for main three spectrum management functionalities of cognitive radio, that is, spectrum sensing, spectrum decision, and spectrum mobility, are explored below for CRSN from the perspective of industrial applications.
