Empirical Observations of Congestion Propagation and Dynamic Partitioning with Probe Data for Large-Scale Systems

Nikolaos Geroliminis, Jun Luo, Yuxuan Ji

Research on congestion propagation in large urban networks has been based mainly on microsimulations of link-level traffic dynamics. However, both the unpredictability of travel behavior and the complexity of accurate physical modeling present challenges, ...

Joint Sink Mobility and Routing to Maximize the Lifetime of Wireless Sensor Networks: The Case of Constrained Mobility

Jean-Pierre Hubaux, Jun Luo

The longevity of wireless sensor networks (WSNs) is a major issue that impacts the application of such networks. While communication protocols are striving to save energy by acting on sensor nodes, recent results show that network lifetime can be prolonged ...

The MicroArray Quality Control (MAQC)-II study of common practices for the development and validation of microarray-based predictive models

Darlene Goldstein, Chenxu Zhao, Mauro Delorenzi, Li Zhang, Vlad Popovici, Jun Luo, Wen Luo, Wei Wang, Ying Liu, Jonathan Koh Boon Han

Gene expression data from microarrays are being applied to predict preclinical and clinical endpoints, but the reliability of these predictions has not been established. In the MAQC-II project, 36 independent teams analyzed six microarray data sets to gene ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

GossiCrypt: Wireless Sensor Network Data Confidentiality Against Parasitic Adversaries

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Resource and cost constraints remain a challenge for wireless sensor network security. In this paper, we propose a new approach to protect confidentiality against a parasitic adversary, which seeks to exploit sensor networks by obtaining measurements in an ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Non-Interactive Location Surveying for Sensor Networks with Mobility-Differentiated ToA

Jean-Pierre Hubaux, Jun Luo, Hersh Vardhan Shukla

Location-awareness is crucial to many applications of sensor networks. Existing location surveying approaches either rely on an inflexible infrastructure or suffer from high computation and communication load. In this paper, we present Non-intEractive lOca ...

Mobility in wireless networks: friend or foe : network design and control in the age of mobile computing

Jun Luo

Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...

DICTATE: DIstributed CerTification Authority with probabilisTic frEshness for Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Securing ad hoc networks is notoriously challenging, notably due to the lack of an on-line infrastructure. In particular, key management is a problem that has been addressed by many researchers but with limited results. In this paper, we consider the case ...
