| | 11 | Software defined radios (SDR) are an enabling technology for spectrum sharing that will support |
| | 12 | new and exciting applications that need the available bandwidth. The dynamic spectrum access paradigm, however, relies on |
| | 13 | secondary users (SUs) being cooperative and protocol-compliant. Wireless networks built upon cognitive radio |
| | 14 | technologies becomes vulnerable and |
| | 15 | their communications easily disrupted in the presence of dishonest or malicious SUs. Further, the |
| | 16 | high programmability associated with SDR devices, while enabling flexible communication, can |
| | 17 | also be exploited by an adversary to launch more sophisticated attacks. Ensuring reliable |
| | 18 | and robust communication for networks of SDRs and cognitive radios is a challenging task that is the |
| | 19 | focus of this NSF project. |
