报告摘要：It is becoming increasingly important for wireless network operators to optimize technological decisions for future business success. As a rational party, an operator wants to maximize his economic returnin the long run when deciding the 4G-technology choice and upgrade timing. But such an optimization is challenging especially when the operator faces technology risks, market competition, and user subscription dynamics. The first part of this technical talk takes all these challenges into account and develops a game theoretic model for studying operators’ equilibrium decisions. We show that competitive operators will take differentiated strategies to upgrade their networks and only asymmetric upgrade timing happens in practice.
The second part of the talk turns to studyparticipatory sensing of smartphones in location-based services. We study how to motivatemassive smartphone usersto acquire sensitive data (e.g., GPS location coordinates) and build data-drivenonline services(e.g., live map of auto traffics).Incentive mechanismsare optimally designed by investigatinginformation asymmetry and smartphone heterogeneity.

报告人简介：LingjieDuanis an Assistant Professor in the Pillar of Engineering Systems and Designat Singapore University of Technology and Design (SUTD), which is established in collaboration with MIT and focuses on top-tier interdisciplinary research. Prof. Duan received Ph.D. in Information Engineering from The Chinese University of Hong Kong in 2012, and he was a visiting scholar in the Department of Electrical Engineering and Computer Sciences at University of California at Berkeley in 2011. Prof. Duan currently leads the Network Economics and Optimizations Lab (NEOL) at SUTD with the main research focus on network economics and optimization, game theory, and resource allocation. During the past few years, he has a number of top-tier international publications and his works on network economics attract ever-increasing attentions from both academia and industry. Recently, he serves as a technical program co-chair of IEEE INFOCOM 2014 workshop on GCCCN and a TPC member of many leading conferences. Besides, he is the receipt of the SUTD-MIT International Design Center Grant in 2012.
