Experience Developing a Vehicular Network Based on Heterogeneous Communication Technologies

Abstract

This chapter describes the experiences and findings deploying a vehicular network architecture supporting different communication technologies. This approach has been developed taking into account key issues regarding mobility and security. These two aspects have been provided by means of the NEMO and IKEv2 protocols, respectively. In addition, thanks to the EAP protocol, transported by IKEv2, an extensible authentication method can be used to implement an access control mechanism. This work also focuses on how the terminal is aware of the surrounding environment in order to boost the handoff processes among heterogeneous networks using the IEEE 802.21 protocol. Apart from the description of the on-board system architecture, a WiMAX/WiFi deployment has been set up at the infrastructure side to validate the development of the mobility and security environment designed for vehicular networks.
