Handover and Load Balancing for Distributed Network Control: Applications in ITS Message Dissemination
Résumé
In this paper, we build upon our prior work on D2-ITS, a flexible and extensible framework to dynamically distribute network control to enable message dissemination in Intelligent Transport Systems (ITS), and extend it with handover and load balancing capabilities. More specifically, D2-ITS' new handover feature allows a controller to automatically "delegate" control of a vehicle to another controller as the vehicle moves. Control delegation can also be used as a way to balance load among controllers and ensure that required application quality of service is maintained. We showcase D2-ITS' handover and load-balancing features using the Mininet-Wifi network simula-tor/emulator. Our preliminary experiments show D2-ITS' ability to seamlessly handover control of vehicles as they move.
