A Simple Distributed ID Assignment Scheme for CSMA/IC Using Well Arranged Rotation ID in Ad Hoc Networks
Carrier Sense Multiple Access / ID Countdown (CSMA/IC) is a collision-free ad hoc MAC protocol. CSMA/IC avoids simultaneous medium access by competing with a local unique ID assig...

Robust frequency synchronization for an OFDMA uplink system disturbed by a Cognitive Radio system interference
In Cognitive Radio (CR) systems, spectrum sensing plays a key role to determine the free frequency bands. However, when the primaryuser (PU) signal spectrum exhibits localized fad...
