SUMMARY
Wireless Sensor Networks (WSNs) exclusively operate over unlicensed bands. Today, significant increases in the applications that use these bands has led to problems of bandwidth allocation and processing bottlenecks.. Hence, WSNs need additional capabilities to combat the interference incurred by other applications.
The Cognitive Radio Sensor Network project seeks to provide a solution through using Cognitive Radio (CR) technology to arm the wireless sensor nodes with Opportunistic Spectrum Access (OSA) capability. OSA enables the use of the most suitable channel for application-specific requirements and also reduce power consumption.

SOLUTIONS
- Utilising the unique features provided by CR concept to incorporate additional capabilities to WSN such as the ability to select the most suitable channel for specific applications
- Adjusting transmission parameters via OSA technology to reduce power consumption
