  • Receiver moved at x km/hr towards the stationary transmitter
  • Measured using DSRC radios:
    • Received Power
    • Bit Error Rate

1. Vehicle 1 and vehicle 2 run into each other.

2. Vehicles can’t observe each other, because

of building. Vehicles transmits vehicle

location each other.

3. Vehicle receives packet and tells driver

warning.

OSU Testbed: Long Distance Communication

Vehicle 1 (Accident vehicle)

(It has LDC and SDC systems.)

●Transmit incident warning occurred at long distance, and tell driver incident warning

Vehicle 2 (Guest’s vehicle)

(It has LDC and SDC systems.)

Warning information about vehicle 1

1) Distance between vehicles: 7 km “Accident 7 km Ahead!”

2) Distance between vehicles: 3 km “Accident 3 km Ahead!”

3) Distance between vehicles: 1 km “Accident 1 km Ahead!”

4) Distance between vehicles: 700 m

“Car Stopping 700 m Ahead!”

5) Distance between vehicles: 300 m

“Car Stopping 300 m Ahead!”

6) Distance between vehicles: 100 m

“Car Stopping 100 m Ahead!”

research directions urban multi hop broadcast umb

Directional Broadcast

Packet dissemination along the road

Source Vehicle

The furthest vehicle in the transmission range of the source vehicle

Research Directions: Urban Multi-hop Broadcast (UMB)

Intersection Broadcast

Start new directional broadcasts along other road segments

GOALS

1. High reliability by acknowledged message delivery

2. Low induced traffic in single and multi-hop scenarios

Control and Intelligent Transportation Research Lab

possible additional directions

Destination Area:

An exit of a highway

Possible Additional Directions

Source

Destination Position (x, y)

Unicast

Geocast

Design Goal:Send packets to a single node whose position is known.

Possible Destinations:Other vehicles, gas stations, restaurants

Design Goal:Send packets to a group of nodes in a geographic region.

Possible Destination:Nodes around a highway exit

other research direction internet access in vehicular networks
Other research direction:Internet Access in Vehicular Networks
  • Goal: Internet access in vehicles
  • Objectives:
    • Providing high end-to-end throughput
    • Preventing starvation of vehicles far away from the gateways

INTERNET

Gateway B

Gateway A

Service Area of Gateway A

Service Area of Gateway B

  • Internet access is accomplished through fixed internet gateways along the road.

: Physical transmission range

  • Vehicles communicate with distant gateways via multi-hopping.

Possibility of linkage and interaction being considered. The OSU-V2V testbed can provide realistic data to be then emulated on KANSEI. KANSEI can provide (in real time) an aggregated model of “the rest of the city”.

  • Code Deployment
  • Scheduling
  • Job Control (Stop, Suspend, Resume, Move)
  • Orchestration (Multi-phase jobs)
  • Testbed Health State
  • Injection
  • Data and Experiment Status
  • Frequency and Key Management
