An IPv6 architecture for cloud-to-vehicle smart mobility services over heterogeneous vehicular networks

In this paper, we provide the specification of a cloud-initiated Point-of-Interest (PoI) application, and illustrate its requirements for a convergence between IPv6 mobility management and Dedicated Short Range Communications (DSRC) geographic services. We propose to extend a flat IPv6 mobility management architecture with a new functional block, namely LIMME (Location & Infrastructure Mobility Management Entity), composed of three key functions: a Location Manager (LM) acting as location anchor point for cloud-based services, a Geographic Mobility Management (GMM) function acting as location proxy for the LM and handling IPv6 mobility, and an Infrastructure Node selector, which selects a route based on geographical data and local infrastructure node conditions. As a proof-of-concept, we implemented these extensions on the iTETRIS ITS simulation platform and illustrated their benefits in enhanced IPv6 mobility management and traffic offloading.
