An Opportunistic Spectrum Scheduling Scheme for Multi-Channel Cognitive Radio Networks
—In this paper, we develop an opportunistic spectrum scheduling scheme for cognitive radio networks. In the proposed scheme, the channel status (i.e., whether being occupied by p...

On Using Probabilistic Forwarding to Improve HEC-Based Data Forwarding in Opportunistic Networks
In this paper, we propose the HEC-PF scheme, an enhancement of our previous H-EC scheme for effective data forwarding in opportunistic networks. The enhanced scheme modifies the a...

Opportunistic Networks: Challenges in Specializing the P2P Paradigm
We introduce the notion of opportunistic networks or oppnets, some of which can be considered a subclass of the peer-to-peer (P2P) networks. Initially, a relatively small seed opp...
