Utility-based power control for peer-to-peer cognitive radio networks with heterogeneous QoS constraints
Transmit-power control is a critical task in cognitive radio (CR) networks. In the present contribution, adherence to hierarchies between primary and secondary users in a peer-to-...

Component based channel assignment in single radio, multi-channel ad hoc networks
In this paper, we consider the channel assignment problem in single radio multi-channel mobile ad-hoc networks. Specifically, we investigate the granularity of channel assignment...

An Adaptive Protocol for Reliable Multicast in Mobile Multi-hop Radio Networks
In this paper we propose a new protocol for reliable multicast in a multi-hop mobile radio network. The protocol is reliable, i.e., it guarantees message delivery to all multicast...

Efficient Resource Allocation with Flexible Channel Cooperation in OFDMA Cognitive Radio Networks
Recently, a cooperative paradigm for single-channel cognitive radio networks has been advocated, where primary users can leverage secondary users to relay their traffic. However, i...

Phase Transition Diagram for Underlay Heterogeneous Cognitive Radio Networks
Abstract--Characterizing the topology and therefore fundamental limits is a must to establish effective end-to-end cognitive radio networking (CRN). However, there lacks complete u...
