Many spectrum sensing methods and dynamic access algorithms have been proposed to
improve the secondary users' opportunities of utilizing the primary users' spectrum …

Dynamic spectrum access in cognitive radio networks can greatly improve the spectrum
utilization efficiency. Nevertheless, interference may be introduced to the Primary User (PU) …

In a distributed cognitive radio network, due to negative network externality, rational
secondary users tend to avoid accessing the same vacant primary channels with others …

This paper proposes a novel virtual Content-Aware Network (CAN) layer as a part of a full
layered architecture, focused, but not limited to, on multimedia distribution with Quality of …

This paper tries to answer the questions of how to enable cooperative communications in
random access networks. And, since cooperation introduces extra transmissions in the …

data-center environment, the administrator needs to understand the root-cause of the issue.
The growing trend of system virtualization, combined with the need to support end-to-end …

This paper investigated the throughput performance of a secondary user (SU) for a random
primary user (PU) activity in a realistic experimental model. This paper proposed a sensing …

To enhance the system throughput in a multiple access network, we discover that
cooperative multiplexing can effectively increase the system traffic. A cooperative ALOHA …

This paper aims at answering the questions of how to enable cooperative communications
in random access networks. And, since cooperation introduces extra transmissions in the …

A challenge when enabling cooperation for conversational multimedia is how to obtain
enough resources from the network. One approach is to use the source dynamics and …
