We address the problem of collaborative sensing in cognitive radios. In a cognitive radio network, all the nodes may sense the spectrum simultaneously. They should then exchange their sensing results in order to improve the reliability of the detection. This exchange of information has to be done efficiently to improve on the bandwidth efficiency of the network. We propose a medium access control...
Small form factor (SFF) software defined radio (SDR) platform is used to implement an experimental cognitive radio for first responders. The system was demonstrated in the 2007 Software Defined Radio technical conference and product exhibition, and is selected for presentation in the demonstrations and experimentation track in the IEEE DySPAN 2008. Different processing tasks are divided between a...
The increasing complexity of engineering systems and automation applications asks for systematic design processes and methodologies. In previous work, a progressive simulation-based design methodology was developed. This methodology views simulation as a driving force for designing and testing engineering systems and supports systematic transitions from simulation models to real system realization...
