tongji s work in 4gtest
Base on the characters of the project, the indicators of the networking test should focus on the performance evaluation of the system.Tongji’s work in 4Gtest
features of dsrc
Features of DSRC
  • Dedicate short rang communications (DSRC) ,IEEE802.11p
  • 75 MHz of band available in U.S.
    • Twice the bandwidth of cellular
    • Approved by FCC
    • Primary allocation
    • Allocation incentive was safety
  • Range: Up to 1000 meters
  • Data Rate: Up to 27 Mbps
    • Tolling will probably use default data rate of 6 Mbps
  • Mobile connection: up to 120 mph
  • High Availability & Low Latency (50ms) Prioritization Service
service oriented research
Service-Oriented Research
  • Safety: improving driving safety and/or traffic efficiency
  • Non-safety: providing information and/or entertainment to the driver

Realistic mobility model

Traffic flow characteristics

-Vehicles speed range -Lanes number

-Vehicles density -Lane changing features

-Traffic regulation

multi channel operation
Multi-Channel Operation

North America FCC 1999

DSRC: 172-184, 7 channels

Channel Coordination

Channel Assignment

mobility prediction
Mobility Prediction

Nodes can rebuild new routes by sensing its neighbours' movements

unnecessary prediction (<200):

A->C1、C2、C3

safe transmission (200<R<240):

A->C4

change route (240<R<250):

A->D->Cn

Mobility prediction

cluster based routing protocol
Cluster-Based Routing Protocol
  • Intra cluster : emergency messages, etc.
  • Inter cluster : non-emergency and long-distance messages, etc.
