2016 conference paper
Connectivity for overlaid wireless networks with outage constraints
International conference on acoustics speech and signal processing, 3771–3775.
TL;DR:
This work provides a new perspective for better understanding of the connectivity of large-scale overlaid networks by using percolation theory to specify a 2-dimensional connectivity region defined as the set of density pairs within which the secondary network is percolated.

2015 conference paper
A unified framework for wireless connectivity study subject to general interference attack
2015 ieee international conference on communications (icc), 7174–7179.
TL;DR:
This paper proposes a unified framework to study the connectivity of wireless networks under a general type of interference attack, which can address diverse applications including Cognitive Radio, Jamming attack and shadowing effect and investigates a 3-dimensional connectivity region.

2014 journal article
Throughput Scaling of Primary and Secondary Ad Hoc Networks With Same-Order Dimensions
IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 63(8), 3957–3966.
author keywords: Ad hoc cognitive radio; network capacity; scaling law
TL;DR:
This paper investigates the scaling law of the network throughput of a special type of heterogeneous networks where a secondary network composed of cognitive users shares the same resources opportunistically with a primary network of licensed users with a weaker condition that the dimensions of the two overlaid networks are on the same order, under the extended network model.

2011 conference paper
On the throughput scaling of cognitive radio ad hoc networks
2011 proceedings ieee infocom, 241–245.
TL;DR:
Surprisingly, this analysis shows that this weaker condition that the dimensions of the two overlaid networks are on the same order does not degrade either network throughput in terms of scaling law, and further reveals the potentials of CR technology in real applications.

2011 conference paper
Transport throughput of secondary networks in spectrum sharing systems
2011 proceedings ieee infocom, 2732–2740.
TL;DR:
The limit of STT, single hop transport capacity (STC), is derived together with a practical upper bound for it, and the broadcast transport throughput (BTT) of the secondary networks is investigated as an extension ofSTT, and its similarity with STT in the nearest neighbor model is revealed.

2010 journal article
Collaborative Quickest Spectrum Sensing via Random Broadcast in Cognitive Radio Systems
IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, 9(7), 2338–2348.
author keywords: Cognitive radio; spectrum sensing; quickest detection; random broadcast
TL;DR:
To alleviate the difficulty of computing the optimal broadcast probability, a simple threshold broadcast scheme is proposed that can achieve substantial performance gain over schemes of random broadcast without regulation and single-user spectrum sensing.

2010 article
Transport Capacity and Connectivity of Cognitive Radio Networks with Outage Constraint
2010 IEEE INTERNATIONAL SYMPOSIUM ON INFORMATION THEORY, pp. 1743–1747.
TL;DR:
The characterization of a capacity metric, single-hop transport capacity, with respect to arbitrarily and randomly located receivers, and a fundamental connectivity metric, node isolation probability, are explored.

2009 conference paper
adaptive quickest change detection with unknown parameter
International conference on acoustics speech and signal processing, 3241–3244.
TL;DR:
A novel adaptive approach is proposed to tackle this problem, which is shown to outperform the celebrated Parallel CUSUM Test and is evaluated through theoretical analysis and numerical simulations.
