Employing Portable Vehicle-To-Infrastructure Transceiver with Network Coding

Abstract

In Vehicle-to-Infrastructure (V2I) technology, transmission between vehicles and infrastructures could be a major challenge due to the moving environment of vehicle, as well as the changing distance and speed of vehicle during the communication with infrastructure. This project starts with the review of past and present researches that are related to V2I communication. Prototype of wireless data transceivers are developed to identify the optimum transmission range. Store-and-forward (SF) algorithm is a process of storing and forwarding data from one data transceiver to another data transceiver. This technique is used to overcome the limitation of transmission range by continuously passing information from one point to another. However, during the transmission, the process taken for data exchanging will affect the entire transmission time. Thus, an algorithm named Network coding (NC) is introduced to reduce the transmission while maintaining the stable connection. NC is a process of combining two or more sources of data to reduce number of transmissions, which is very useful in data exchanging. These algorithms are computed in MATLAB and simulated for performance analysis. Apart from that, SF and NC are also programmed into wireless data transceivers to carry out real time experiment. Simulation results showed that SF uses 0.1664 s to exchange 256 bits data while NC spends 0.1266 s to complete the same mission. Hence NC is showing better performance than SF.
