Continuity of Service, Security and QoS for Transportation Systems

Abstract and main objectives

Over the last years, network connectivity support in transportation systems has been one of the main research topics in computer networks engineering. Most of the research has been focused on routing mechanisms and on network mobility support, but there are still many other aspects to cover. This project aims to concentrate on two scenarios. The first scenario is network connectivity on trains, where high-speed trains have embedded femtocells that connect to the outside using the most suitable wireless technology at a given time, and that offer secure access to communication to the cellular phones and WiFi devices of the passengers. The second scenario is hybrid sensor and vehicular networks (HSVNs), where vehicle-to-vehicle communications and vehicle-to-roadside sensor communications are combined to obtain information about road state, weather conditions, traffic jams, crashes, potential dangers and so on, in order to improve road safety. This information must be exchanged in a secure, privacy-friendly, reliable way.

Scenario 1

Scenario 2

The issues in these scenarios, not yet sufficiently studied in the literature, and that we shall cover in this project, can be grouped in four main areas:

  • Continuity of service, i.e., mechanisms needed to provide network communication in vehicles (trains, buses, cars), possibly using different heterogeneous networks to connect with the outside world, with no interruption or with minimal service disruptions.

  • Quality of service (QoS) awareness, i.e., solutions to attain seamless connectivity in these scenarios while maintaining end-to-end QoS to fulfill the constraints of multimedia services.

  • Security and identity, i.e., to preserve security during the handover process and to transparently handle roaming access across different administrative domains, managing different user identities for different services.

  • Privacy, since any information exchanged between users or submitted to service providers is subject to potential misuse.
