  1. Mobility Management, Privacy, and other Issues in Vehicular Networking Sandra L. Céspedes BroadbandCommunicationsResearch Group (BBCR) University of Waterloo MOBOPTS RG – 81st IETF meeting, Québec, Canada

  2. Outline • Introduction to Vehicular networking • Mobility management • Interworking HIP-PMIPv6 scheme • Multi-hop PMIPv6 • Related work: • Privacy • Applications • Traffic and mobility • Current work and open issues

  3. Vehicular networking • Different types of communications: • Vehicle to Infrastructure (V2I) • Vehicle to Vehicle (V2V) • Hybrid • Different types of services: • Safety and emergency communications • Traffic monitoring and management • Information and entertainment applications • Different types of access technologies • 802.11p/WAVE • 3G/4G/LTE • WiFi…

  4. Vehicular networking • Unique characteristics: • Restricted Mobility • Availability of location information • No strict energy consumption constraints • Mixed types of communications: infrastructure-based, mobile hot-spots, and ad-hoc • Some research challenges • Frequent link disconnection • Highly dynamic spacial-temporal traffic conditions • Heterogeneity of data dissemination • Efficient and adaptive IP support and IP mobility • Anonymity and location privacy H.T. Cheng, H. Shan, and W. Zhuang, “Infotainment and road safety service support in vehicular networking: From a communication perspective,” Mechanical Systems and Signal Processing, vol. 25, Aug. 2010, pp. 2020-2038.

  5. Mobility Management • Previousresearch • Evaluation of NEMO RO solutionsfor vehicular communicationsnetworks [1] • Interworking HIP-PMIPv6 schemefor IP mobility in urban vehicular scenarios [2] • Mobile networks (vehicles, buses, trains) • No mobility-enabled nodes (devices with traditional • TCP/IP stack) • Mobility-enabled nodes (HIP-enabled mobile phones, laptops, hand held devices) [1] S. Céspedes, X. (Sherman) Shen, C. Lazo. "IP Mobility Management for Vehicular Communication Networks: Challenges and Solutions", in IEEE Communications Magazine . May 2011 [2] S. Céspedes, X.

  6. Mobility Management Intra-domain handover for HIP-enabled nodes Inter-domain handover for HIP-enabled nodes

  7. Mobility Management • Analytical evaluation • Mobile network analysis • Analysis of signalling cost per vehicle: • Localization updates and Packet delivery • Fluid Flow Model • Comparison to NEMO BS. • Mobile node analysis • Analysis per node (legacy & HIP-enabled): • Handover delay and expected number of packets dropped • Delay analysis during handover process • Comparison to NEMO, MIP, HIP and Novackzi

  8. Mobility Management Intra-domain handover Inter-domain handover Signalling and packet delivery cost
