An M2M-Based Interface Management Framework for Vehicles with Multiple Network Interfaces

The Intelligent Transportation System (ITS) can be considered the most representative example of Machine-to-Machine (M2M) applications in a standardization and commercial market. To support the applications, utilizing multiple network interfaces and providing appropriate network connectivity to them are the key issues in order to meet different network requirements of M2M applications on ITS devices. Moreover, different from applications which are controlled by a human operator, the ITS device with M2M application is required to decide the appropriate air interface and network for each application by itself according to the predefined policy and network status. In this paper, we therefore propose a novel multiple network interface management framework for ITS devices with M2M applications having their different requirements and constraints based on the CALM architecture. This can provide the M2M applications with extensible and flexible system environments based on the CALM architecture.
