Almost Optimal Channel Access in Multi-Hop Networks With Unknown Channel Variables
Yaqin Zhou, Xiang-yang Li, Fan Li +3
We consider distributed channel access in multi-hop cognitive radio networks. Previous works on opportunistic channel access using multi-armed bandits (MAB) mainly focus on single-…
BlueSky: Realizing Buried Potential of Bluetooth to Sustain a Large-scale Multi-hop Network
Xinfeng Li, Chenshu Wu, Xiaoyuan Wang +3
Traditionally, Bluetooth has been deemed unsuitable for sustaining a large-scale multi-hop network. There are two main reasons: severe frequency channel collisions under a large-sc…
PPS: Privacy-Preserving Strategyproof Social-Efficient Spectrum Auction Mechanisms
He Huang, Xiang-Yang Li, Yu-e Sun +2
Many spectrum auction mechanisms have been proposed for spectrum allocation problem, and unfortunately, few of them protect the bid privacy of bidders and achieve good social effic…
TEXIVE: Detecting Drivers Using Personal Smart Phones by Leveraging Inertial Sensors
Cheng Bo, Xuesi Jian, Xiang-Yang Li
In this work, we address a fundamental and critical task of detecting the behavior of driving and texting using smartphones carried by users. We propose, design, and implement TEXI…
Towards Distribution-Free Multi-Armed Bandits with Combinatorial Strategies
Xiang-yang Li, Shaojie Tang, Yaqin Zhou
In this paper we study a generalized version of classical multi-armed bandits (MABs) problem by allowing for arbitrary constraints on constituent bandits at each decision point. Th…
OMG: How Much Should I Pay Bob in Truthful Online Mobile Crowdsourced Sensing?
Dong Zhao, Xiang-Yang Li, Huadong Ma
Mobile crowdsourced sensing (MCS) is a new paradigm which takes advantage of the pervasive smartphones to efficiently collect data, enabling numerous novel applications. To achieve…
Near-Optimal Truthful Auction Mechanisms in Secondary Spectrum Markets
Yu-e Sun, He Huang, Xiang-Yang Li +4
In this work, we study spectrum auction problem where each request from secondary users has spatial, temporal, and spectral features. With the requests of secondary users and the r…
Efficient Construction of Spanners in -Dimensions
Sanjiv Kapoor, XiangYang Li
In this paper we consider the problem of efficiently constructing -vertex fault-tolerant geometric -spanners in $\dspace$ (for and ). Vertex fault-tolerant sp…
Throughput Optimizing Localized Link Scheduling for Multihop Wireless Networks Under Physical Interference Model
Yaqin Zhou, Xiangyang Li, Min Liu +3
We study throughput-optimum localized link scheduling in wireless networks. The majority of results on link scheduling assume binary interference models that simplify interference…
