Latency Measurements of V2X Communication

Abstract

V2X communication plays one of the important roles for future autonomous vehicle. Current V2X communication is more directed towards DSRC (Dedicated Short Range Communications). What if the DSRC law is not enforced and some other technology such as D2D (Device to Device) based on LTE (Long Term Evolution) will provide good results and become possible alternative. The scope of this project is to have a sniffer that has the capability to process transmit and receive the data and could able to interface all of the following devices DSRC, LTE and D2D (LTE based communication without involvement of Base Station) and any other possible medium of communication for V2X communication. And also, to have a database that has the capability to help in the future of autonomous vehicles. This thesis explains the research study, done for one of the performance evaluation of V2X communication. It can be further continued to develop a device and a server with more functionalities for V2X communication. In V2V communication network, performance evaluation is one of the key factors that need to be considered. To address the evaluation criteria, I have analyzed the elapsed time in reading the GPS (Global Positioning System) sensor and CAN (Controller Area Network) bus information from the vehicle before transmitting the data to the Network (IEEE802.11p or LTE) and also after the transmission. I have developed a c code, which can read the data from the GPS sensor and the CAN bus, and add a time stamp to the real time data to analyze the elapsed time.
