In this paper, we exploit channel diversity for opportunistic spectrum access (OSA). Our approach uses channel quality as a key criterion in selecting channels to use for opportunistic transmission. The difficulty of the problem comes from the fact that when the channel condition is poor, further channel probing, although may lead to better channel conditions and hence yield higher throughput will...

Byzantine attack is the attack performed by a fully trusted node that's turned rogue and already has passed all the authentication and verification processes. When a trusted node is turned rogue, it can easily perform DoS...
