R&D Projects
The main goal of the project was to develop an adaptive security framework for secure and safe ITS applications. To address this task, we first analysed the security and functional requirements of ITS communication systems followed by road safety application and use cases. We also performed extensive experimental bench-marking of ITS security services in realistic operating conditions. Finally, we designed innovative ITS application framework for the dynamic monitoring and adaption of the security, performance and safety features, to cope with changes in applications/user needs and/or contexts.
This research work proposes several efficient multi-service packet transmission techniques that have been developed and evaluated for future road traffic applications in VANETs. Specifically, for safety applications, power and rate control techniques have been developed using new QoS metrics. To efficiently transmit periodic safety messages, an adaptive space division multiple access technique has been developed that solves bandwidth under-utilization problem of SDMA techniques. Moreover, a time-slotted multi-hop broadcast technique has been developed for efficient dissemination of emergency warning messages. Finally, techniques for transmission of multimedia packets and support an electric vehicle information system have been proposed.
