Session 302: Wireless Access for Vehicular Environments (WAVE) Technology

Thursday, 3 December 2009 . 10:15 - 16:00 (HST - Hawaii Standard Time)

Vehicles have been operating on roadways on this planet for more than a century in an isolated way. We are at the right time to connect these vehicles and bring our society into a new age. Similar to the evolution of computer networks, when millions of computers were connected to share resources and information, the Internet emerged and some profound positive changes were made to our way of our life and work.

Title: Service Management for ITS using WAVE (1609.3) Networking
Speaker: Tim Weil  JD Biggs and Associates
Abstract:  Automotive networking on US highways is moving into high gear.  Smart cars, connected vehicles, intelligent transportation systems (ITS), vehicular ad-hoc networks (VANET), and vehicle telematics represent parallel and overlapping technologies and services that will define the future of the American roadway systems .  The integration of  computing technology and expanding communication services is driving the growing research and development efforts to integrate vehicles and roadway telematic services to improve preventive vehicle safety, reduce traffic congestion, and enable new applications for vehicle maintenance and commercial services.  
Industrial and governmental efforts are underway to accelerate the introduction of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications functions.  In the United States these major ITS projects have included US DOT IntelliDrive, CAMP/VSC-2; SafeTrip21, IEEE WAVE, California PATH, and the Connected Vehicle Proving Center (CVPC).
An Intelligent Transportation System (ITS) technical architecture for Service Management has been developed based on IEEE 1609 Wireless Access for Vehicular Environments (WAVE) standards for secure vehicle-to-vehicle and vehicle-to-infrastructure wireless communication.  This study defines an ITS Service Management model based on  the networking (IEEE 1609.3), and security (IEEE 1609.2)  protocols.  An examination of the working model demonstrates the use of a 1609.3 Provider Service Identifier (PSID)  to provision and secure ITS services and applications using the DSRC/WAVE communication stack.

Title:  A Vehicular Network Simulator and Testbed over Mobile Wireless Channels
Speaker: Fuqiang Liu (Tongji University, China)
Abstract:This talk will give a brief overview of the whats and whys of vehicular networking, taking into account the realistic constraints that affect the design of vehicle-to-vehicle (V2V) communications and vehicular infrastructure integration (VII) in China. Several issues and challenges will be reviewed for the realization of vehicular wireless networks, including theoretical research on enabling technology, a simulator for vehicular network, and a hardware-based real-world testbed.

The key research topics include multi-channel coordination and channel scheduling, realistic mobility modeling and mobility prediction, cluster-based routing protocols, improved MIMO channel models for vehicular networks and etc..

The system simulator is developed to mitigate the limitations on the real-world testbeds.  Preliminary results already demonstrate the applicability of the simulator in conducting performance evaluation and sensitivity analysis for the scenarios which are difficult to assess to by using existing hardware testbeds.
The simulator makes the use of real map data (such as the map of Jiading campus, Tongji Univ.) and traffic, as well as realistic mobility models that include the information of both roads and the vehicle movements.
In addition, a testbed of vehicular communications has been developed as well.
The system simulator and testbed are applicable to evaluate the performance of the vehicular networks with a MIMO configuration for the real-world V2V and VII activities. Meanwhile, we focus on the theory and technologies of vehicular communications and how it can be integrated into a 4G-testing system to verify new and advanced techniques that likely will be adopted in the next generation wireless communication systems, such as WiMAX and LTE. Furthermore, a comprehensive simulation platform for 4G systems is constructed.

Title: Introduction of a Vehicular Networks Simulator (VSN) for Research, Design and
Development of WAVE Systems
Speaker: Weidong Xiang (University of Michigan, Dearborn, USA)
Abstract: In this talk, we will introduce and release a WAVE simulator for research and engineering purposes. The unique of the simulator lies on its cross-layer and systematic strategy built upon WAVE channel models that are proposed by the center of vehicular communications and networks, at University of Michigan, Dearborn based on extensive experiments. The simulator will integrate signal format, vehicle type, transceiver settings, TIGER database (shapefiles), terrains, road situations, vehicle distribution models and rational driver behaviors.  The simulator is capable of offering physical layer specifications including signal coverage, channel fading, bit error rate (BER), packet error rate (PER), and packet latency.

It also has interface to high layer modules and protocols. The developed simulator provides a confident and truthful evaluation for high layers' algorithms, protocols and performances. A certain  amount of software will be available for the participants and audience for free.

In addition, we will update the activities on a field programmable gate array (FPGA)-based WAVE prototype based on the IEEE 802.11p standard (draft). Such prototypes can be used as WAVE development kits for research and development, onboard units (OBUs)/roadside units (RSUs) for building up WAVE testbed, reference models for WAVE application specific integration circuits
(ASIC) chip design.
