Channel Bonding in Cognitive Radio Sensor Networks

Abstract

Wireless sensor networks have gained high importance in many fields, including military, industrial, and the consumer industry. It is due to the fact that these sensors can be deployed almost anywhere and communicate autonomously with each other and/or their gateway devices. Introducing cognitive radio capabilities into these sensor nodes can considerably improve the spectrum utilization, albeit on the cost of additional processing complexities and higher power consumption. In Cognitive Radio Sensor Networks (CRSNs), improving the process of channel bonding may enhance the overall efficiency and effective use of available bandwidth, thereby meeting the requirements of the network of wireless sensor nodes. This chapter discusses issues in the implementation of channel bonding in CRSNs and how to maximize the channel capacity without introducing any harmful interference. Additional constraints and challenges for CRSN nodes are discussed here as future directions and research.
