LDM-based dynamic network discovery and selection for IPv6 mobility management optimization in C-ITS environments

Abstract

ITS comprises any information and communication technologies applied to transport infrastructures for improving the performance of traffic management and warning systems, productivity and efficiency of ITS services. Benefits of ITS can be further enhanced if ITS entities continuously communicate with each other and exchange relevant information using Cooperative ITS (C-ITS) techniques. C-ITS gives scope for V2X communication technologies like Vehicle-to-Vehicle (V2V), Vehicle-to-Roadside (V2R) and Vehicle-to-Infrastructure (V2I) schemes. The current C-ITS protocol stack relies on heterogeneous wireless access networks, the communication diversity covers Wi-Fi, DSRC, CALM, 3G, 4G/LTE/LTE-A, and Satellite among others. This fact demands the design and implementation of context-aware, resource efficient, scalable, and optimized Layer 3 mobility management mechanisms integrated into the C-ITS standards. To provide the base infrastructure for such mechanisms, here we introduce a dynamic network discovery and selection framework relying on the tools of Local Dynamic Map (LDM) and Cooperative Awareness Message (CAM). A proof of concept implementation that demonstrates the feasibility of our approach is also presented and evaluated.
