Overview:

Software defined radios (SDR) are an enabling technology for spectrum sharing that will support new and exciting applications that need the available bandwidth. The dynamic spectrum access paradigm, however, relies on secondary users (SUs) being cooperative and protocol-compliant. Wireless networks built upon cognitive radio technologies becomes vulnerable and their communications easily disrupted in the presence of dishonest or malicious SUs. Further, the high programmability associated with SDR devices, while enabling flexible communication, can also be exploited by an adversary to launch more sophisticated attacks. Ensuring reliable and robust communication for networks of SDRs and cognitive radios is a challenging task that is the focus of this NSF project.
