Intelligent Transport Systems

  • Motivations
  • Improving transportation in terms of safety,

mobility, productivity, environmental impact...

  • main goals : road fatalities, infrastructure

management, new on-board services

  • ITS applications
  • Infrastructure oriented applications

for optimizing the infrastructure management (transit, freeway, freight, emergency organization...)

  • Vehicle oriented applications

for increasing the road safety (crash prevention, alerts, visibility distance...)

  • Driver oriented applications

for improving the road usage (traffic jam, road work information, payment...)

  • Passenger oriented applications

for offering new services on board (Internet access, distributed games, tourist info...)

Scientific issues

Highly dynamic ad hoc networks

  • Next step in networking and distributed alg.

wired network mobile terminal mobile user mobile network mobile ad hoc networks

dynamic ad hoc networks

hand-over... virtual structures management (tree...) MobileIP with infrastructure without infrastructure dynamic Cellular MANET VANET Internet, IP routers, fixed servers

?

  • Impact of the dynamic
  • impact on network layers

link (2), network (3), transport (4)

  • impact on distributed algorithms

fault tolerance, data sharing...

  • impact on trusty and security

who believe ? what information is reliable ?

  • algorithms necessary embedded
  • ptimizations depending on the context...

Heudiasyc contributions

  • Point of view : dynamic networks are different !

re-thinking networking and distributed algorithms should be addressed simultaneously

  • Work done and in progress
  • IEEE 802.11 study fairness, network capability
  • Messages forwarding conditional transmissions
  • Data flow transport transport protocols, V2I arch.
  • Distributed algorithms

best-effort paradigm, self-stabilization... group-membership, data gathering...

  • Trust in distributed data
  • Security in dynamic ad hoc networks
  • Context aware optimizations
  • Airplug software suite and test-bed
  • Validation : theory ↔ practice

Modeling & proofs Simulation & analysis Prototyping & road test-beds

Groups service for inter-vehicles applications

  • Specific groups based applications
  • some services are based on collaboration

driving, diagnostic, perception, infotainment...

  • collaboration ❀ group

❀ to be maintain as long as possible

  • no collaboration with far vehicles

either useless (driving, diagnostic, perception...)

  • r inefficient (chat, games...)

❀ constraint on the diameter

  • GRP : best-effort group service
