2010 journal article

Location-Aided Fast Distributed Consensus in Wireless Networks

IEEE TRANSACTIONS ON INFORMATION THEORY, 56(12), 6208–6227.

By: W. Li n, H. Dai n  & Y. Zhang n

author keywords: Clustering; distributed computation; distributed consensus; message complexity; mixing time; nonreversible Markov chains; time complexity
TL;DR: The idea of Markov chain lifting is studied to accelerate the convergence of distributed consensus, and two general pseudoalgorithms are presented that achieve the same scaling law in averaging time as the centralized scheme in wireless networks for all r satisfying the connectivity requirement.

A Real Orthogonal Space-Time Coded UWB Scheme for Wireless Secure Communications

EURASIP JOURNAL ON WIRELESS COMMUNICATIONS AND NETWORKING.

By: Y. Zhang n & H. Dai n 

TL;DR: A comparison of the proposed space-time coding scheme for impulse radio UWB systems with the direct sequence spread spectrum (DSSS) technique demonstrates that proper combination of UWB and space- time coding can provide substantial enhancement to wireless secure communications over other concurrent systems.

2009 conference paper

Structured variational methods for distributed inference in wireless ad hoc and sensor networks

International conference on acoustics speech and signal processing, 2773–2776.

By: Y. Zhang n & H. Dai n 

TL;DR: A variational message passing framework is proposed for Markov random fields, which is computationally more efficient and admits wider applicability compared to the belief propagation algorithm. (via Semantic Scholar)

2007 journal article

Energy-efficiency and transmission strategy selection in cooperative wireless sensor networks

JOURNAL OF COMMUNICATIONS AND NETWORKS, 9(4), 473–481.

By: Y. Zhang n & H. Dai n 

author keywords: energy efficiency; sensor networks; virtual multiple-input multiple-output (MIMO)
TL;DR: Analysis in the wideband regime reveals that, while receive diversity introduces significant improvement in both energy efficiency and spectral efficiency, further improvement due to the transmit diversity of STBC is limited, as opposed to the superiority of the SM scheme especially for non-trivial spectral efficiency.
