Mapping Personal Trip OD from Probe Data

The paper analyses the expected value of OD volumes from probe with fixed error, error that is proportional to zone size and inversely proportional to zone size. To add realism to the analysis, real trip ODs in the Tokyo Metropolitan Region are synthesised ...

Secure Position-Based Routing for VANETs

Panagiotis Papadimitratos, Charles Harsch

Vehicular communication (VC) systems have the potential to improve road safety and driving comfort. Nevertheless, securing the operation is a prerequisite for deployment. So far, the security of VC applications has mostly drawn the attention of research ef ...

Small-Scale Robot Formation Movement Using a Simple On-Board Relative Positioning System

Alcherio Martinoli, James Pugh

We explore the problem of smallscale multirobot formation control using only an unsophisticated onboard relative positioning module. The robotic setup and module are implemented and tested in a realistic virtual simulator, using standard formation types an ...

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 ...

Signal Processing Challenges in Distributed Stream Processing Systems

Pascal Frossard

Distributed stream processing represents a novel computing paradigm where data, sensed externally and possibly preprocessed, is pushed asynchronously to various connected computing devices with heterogeneous capabilities for processing. It enables novel ap ...

Locating Mobile Nodes with EASE: Learning Efficient Routes from Encounter Histories Alone

Martin Vetterli, Matthias Grossglauser

Routing in large-scale mobile ad hoc networks is challenging because all the nodes are potentially moving. Geographic routing can partially alleviate this problem, as nodes can make local routing decisions based solely on the destinations' geographic coord ...

Custom GPS-Correction Server for Real-Time Trajectography

Hervé Gontran

Centimeter-level real-time kinematic (RTK) positioning is one of the most widely used surveying techniques. Broadcasting GPS-RTK corrections via Internet-based services has become a new communication procedure to achieve “instantaneous” positioning with hi ...

Frugal Mobile Objects

Rachid Guerraoui, Maxime Monod, Benoît Garbinato, Jesper Honig Spring

This paper presents a computing model for resource-limited mobile devices. The originality of the model lies in the integration of a stronglytyped event-based communication paradigm with abstractions for frugal control, assuming a small footprint runtime. ...
