As a basic enabler of our modern society, road vehicle transportation has

become a major source of societal concerns.

Question: how to evaluate ideas and protocols in Vehicular Network ?

Traffic collisionCooperative vehicle safety system

Air pollution from cars

Energy efficiency

Traffic jam

Low-carbon life Hybrid car

Smart traffic

Cooperative driving and vehicle platooning

Individual, passive behaviorCooperative, active behavior

System Architecture

Objectives:

To enable evaluating Vehicular Sensing and Control (VSC )

networking solutions in a wide range of scenarios and at

scale

To bridge the GENI and VSC research as well as application

communities for self-sustaining GENI development

To evaluate the design and implementation of GENI

Design & main contribution

An open research infrastructure developed on vehicular

networks with the integration of GENI resources (e.g., GENI rack,

GENI Backbone, WiMAX) Resource virtualization

Allocate the resources to different experiments or applications

In-field vehicle internal state sensing and surrounding condition sensing Leverage openxc box and camera to sense

Simultaneous operation of real-world applications and experiments Fuel economy, link properties study, vehicle detection and location

Parallel, distributed emulations on GENI racks with realistic sensing

data Fed by real-world traffic to help improve the physical-layer model,

emulation, and protocol evaluation at scale

Key Technology

Resource virtualization

Serve different users with resource isolation and management

VSC Networking emulation with GENI racks

Use the real-time traffic and archival

of real-world vehicle behavior to

enable and high-fidelity, at-scale

evaluation of networked VSC solutions

Network constraints: the VSC platform should be within the coverage of the WiMAX network

One question: What will happen if it is out of the WiMAX network.

Current & future

Current status

System development

Develop prototype of VSC platform

Collect preliminary data

Build applications and conduct experiments

Tomorrow of the VSC Networking Platform

Optimization and improvement

Develop useful tools to facilitate operations and applications

Note: this demo helps illustrate the capability of VSC platform.

However, its capabilities are not limited at this level. It is under

continuous development.
