On Spectrum and Infrastructure Sharing in Multi-Operator Cellular Networks
Shanshan Wang, Konstantinos Samdanis, Xavier Costa Perez +1
In this paper, we introduce a mathematical framework for analyzing and optimizing multi-operator cellular networks that are allowed to share spectrum licenses and infrastructure el…
Distributed Power Allocation and Channel Access Probability Assignment for Cognitive Radio
Orestis Georgiou, Mohammud Z. Bocus, Shanshan Wang
In this paper, we present a framework for distributively optimizing the transmission strategies of secondary users in an ad hoc cognitive radio network. In particular, the proposed…
Directional antennas improve the link-connectivity of interference limited ad hoc networks
Orestis Georgiou, Shanshan Wang, Mohammud Z. Bocus +2
We study wireless ad hoc networks in the absence of any channel contention or transmit power control and ask how antenna directivity affects network connectivity in the interferenc…
Location, location, location: Border effects in interference limited ad hoc networks
Orestis Georgiou, Shanshan Wang, Mohammud Z. Bocus +2
Wireless networks are fundamentally limited by the intensity of the received signals and by their inherent interference. It is shown here that in finite ad hoc networks where node…
Exploiting Channel Correlation and PU Traffic Memory for Opportunistic Spectrum Scheduling
Shanshan Wang, Sugumar Murugesan, Junshan Zhang
We consider a cognitive radio network with multiple primary users (PUs) and one secondary user (SU), where a spectrum server is utilized for spectrum sensing and scheduling the SU…
Spectrum Shaping via Network Coding in Cognitive Radio Networks
Shanshan Wang, Yalin E. Sagduyu, Junshan Zhang +1
We consider a cognitive radio network where primary users (PUs) employ network coding for data transmissions. We view network coding as a spectrum shaper, in the sense that it incr…
