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…
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…
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…
Efficient Construction of Dominating Set in Wireless Networks
Xiaohua Xu, Xiang-Yang Li
Considering a communication topology of a wireless network modeled by a graph where an edge exists between two nodes if they are within each other's communication range. A subset $…
MLLS: Minimum Length Link Scheduling Under Physical Interference Model
Xiaohua Xu, Jiannong Cao, Xiang-Yang Li
We study a fundamental problem called Minimum Length Link Scheduling (MLLS) which is crucial to the efficient operations of wireless networks. Given a set of communication links of…
Link Scheduling for Throughput Maximization in Multihop Wireless Networks Under Physical Interference
Yaqin Zhou, Xiang-Yang Li, Min Liu +2
We consider the problem of link scheduling for throughput maximization in multihop wireless networks. Majority of previous methods are restricted to graph-based interference models…
Rejecting the Attack: Source Authentication for Wi-Fi Management Frames using CSI Information
Zhiping Jiang, Jizhong Zhao, Xiang-Yang Li +2
Comparing to well protected data frames, Wi-Fi management frames (MFs) are extremely vulnerable to various attacks. Since MFs are transmitted without encryption, attackers can forg…
Opportunistic Forwarding with Partial Centrality
Peiyan Yuan, Huadong Ma, Xiang-Yang Li +2
In opportunistic networks, the use of social metrics (e.g., degree, closeness and betweenness centrality) of human mobility network, has recently been shown to be an effective solu…
Network Agile Preference-Based Prefetching for Mobile Devices
JunZe Han, Xiang-Yang Li
For mobile devices, communication via cellular networks consumes more energy, and has a lower data rate than WiFi networks, and suffers an expensive limited data plan. However the…
