An Efficient Vehicle Communication Network Topology with an Extensible Framework

This paper proposes an extensible solution that gives support to recent growth in wireless communication and allows developers outside of the automotive industry to develop applications leveraging vehicle to vehicle communication. The suggested software architecture, which would integrate with the automotive open source architecture (AUTOSAR) standard, has primary focus on supporting applications for safer vehicles and also provides the foundation for developing personal and entertainment applications that can be operated within vehicles. The proposed architecture finds its applications in collision avoidance, autonomous navigation, and direct vehicle to vehicle communication for negotiating pass-through at intersections. The communication network manager is a critical part of the framework, and it includes a new Vehicle Ad-hoc Network (VANET) topology for communication with other vehicles. The proposed topology, that can have at most one intermediate hop to communicate any two vehicles, assumes conformance with IEEE 802.11p and the dedicated short range communication (DSRC) standard.
