Cognitive Multiple Access Networks
- PROC. IEEE INT’L. SYMP. INFO. THEORY
, 2005
"... A cognitive radio can sense the transmission of other users in its environment and possibly extract the corresponding messages. It can use this information to transmit over the same channel while reducing interference from, and to other users. In this paper, we define inter/intra-cluster competitive ..."

-like technique to mitigate interference. We construct an achievable region for the inter-cluster behavior of two multiple access channels. In the Gaussian case, we compare our achievable region to that of competitive behavior as well as that of cooperative behavior.
Cognitive multiple access via cooperation: Protocol design and performance analysis
- IEEE Trans. on Information Theory
, 2007
"... Abstract—In this paper, a novel cognitive multiple-access strategy in the presence of a cooperating relay is proposed. Exploiting an important phenomenon in wireless networks, source burstiness, the cognitive relay utilizes the periods of silence of the terminals to enable cooperation. Therefore, no ..."

COGNITIVE MULTIPLE ACCESS FOR COOPERATIVE COMMUNICATIONS AND NETWORKING
, 2009
"... In cooperative communications different network nodes share their antennas and resources to form a virtual antenna array and improve their performance through spatial diversity. This thesis contributes to the advancement of cooperative communications by developing and analyzing new multiple access c ..."

1 On Ergodic Sum Capacity of Fading Cognitive Multiple-Access and Broadcast Channels
, 806
"... Abstract — This paper studies the information-theoretic limits of a secondary or cognitive radio (CR) network under spectrum sharing with an existing primary radio network. In particular, the fading cognitive multiple-access channel (C-MAC) is first studied, where multiple secondary users transmit t ..."

1Fading Cognitive Multiple-Access Channels With Confidential Messages
"... The fading cognitive multiple-access channel with confidential messages (CMAC-CM) is investigated, in which two users attempt to transmit common information to a destination and user 1 also has confidential information intended for the destination. User 1 views user 2 as an eavesdropper and wishes t ..."

"... This paper presents a definition and framework for a novel type of adaptive data network: the cognitive network. In a cognitive network, the collection of elements that make up the network observes network conditions and then, using prior knowledge gained from previous interactions with the network ..."

is needed to translate the user’s end-to-end goals into a form understandable by the cognitive process. The cognitive network also depends on a Software Adaptable Network that has both an external interface accessible to the cognitive network and network status sensors. These devices are used to provide
1 On the Maximum Sum-rate Capacity of Cognitive Multiple Access Channel
, 2006
"... Abstract — We consider the communication scenario where multiple cognitive users wish to communicate to the same receiver, in the presence of primary transmission. The cognitive transmitters are assumed to have the side information about the primary transmission. The capacity region of cognitive use ..."

Cognitive Multiple Access Network with Outage Margin in the Primary System
"... Abstract—This paper investigates the problem of spectrally efficient operation of a multiuser uplink cognitive radio system in the presence of a single primary link. The secondary system applies opportunistic interference cancelation (OIC) and decodes the primary signal when such an opportunity is c ..."
