Abstract

AbstractInter-Vehicle Communication (IVC) is an important component of the ITS architecture, that enables Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. GeoNet project brought the IVC one step further by enabling transparent IP connectivity between vehicles and the infrastructure. Specifications produced by the GeoNet project have been incorporated into several ETSI standards, which define the geonetworking protocol layer and the IPv6-over-geonetworking adaptation layer. In this paper, we propose an ETSI complaint geonetworking protocol layer on the well known NCTUns simulation framework. We discuss the architecture of our implementation as well as NCTUns specific issues encountered during the implementation. We believe that, with this contribution, the researchers are provided with a scalable and flexible framework with Berkeley socket API access to applications and SQL based performance logging for post simulation evaluations.

Highlights

Inter-Vehicle Communication (IVC) is a promising technology for the generation of automotive vehicles
European Telecommunications Standards Institute (ETSI) TC Intelligent Transportation System (ITS) and ISO TC204 are developing a set of standards for cooperative ITS, which allow ITS stations including vehicles, road infrastructures and other peers to be reachable through the Internet to cooperate and exchange information with each other for road safety, traffic efficiency and infotainment services
// each function has a specific run interval. // Initialize GeoNetworking layer; ID, address, timers, etc.; Initialize GeoNetworking port; Initialize user application port; while TRUE do check for a packet from geonetworking; if received any packet put the received packet to the incoming queue; check packet type and invoke appropriate module; end check for a packet from user application; if received any packet put the received packet to the output queue; end if beacon interval invoke beacon sender; end if sender interval invoke packet sender; end if Location table entry (LocTE) time-out invoke position management module; end usleepAndReleaseCPU() ; end Conclusion and future work There are several projects and researches based on the integration of IVC systems and Internet

Summary

Introduction

Inter-Vehicle Communication (IVC) is a promising technology for the generation of automotive vehicles. Our focus in this work is to implement a geonetworking protocol layer, which is compatible with the ETSI media-independent standard This will enable researchers to test their applications in an ETSI complaint simulation environment. The main advantage is the availability of precise and well tested models of communication protocols Most of these simulation environments provide limited support for the node mobility. SUMO and ns-3 are two open source platforms, respectively for traffic and wireless simulation, which are coupled by a third block called iTETRIS Control System (iCS) Another approach to perform simulation of IVC protocols is to use mathematical models. Besides support for node mobility, native network socket programming interface along with TCP/IP, and position information, NCTUns allowed us to use the real IEEE 802.11p physical layer in our simulations. NCTUns specific issues This section explains NCTUns specific issues that we had to deal with during the implementation of our ETSI complaint geonetworking layer
