Roadside infrastructure transmission of VANET using Power Line Communication

Vehicular ad-hoc Network (VANET) is an emerging mobile wireless ad hoc communication system applied on the roads, realizing multi-hop wireless communication between Vehicles to Vehicles, Vehicles to Roadside Infrastructure (RSI) and between RSIs. The Vehicle transmits the information to the nearest RSI that is connected to gateway either wirelessly or wired. The deployment of a roadside infrastructure is expensive and cannot be efficiently implemented using low-cost hardware. Power Line Communication (PLC) refers to the utilization of electricity transmission power lines for communication medium whilst simultaneously serving as a physical medium for realization of data transmission. PLC today are not only used for remote meter reading, home automation and other low-speed control systems but are also utilized at physical layer of Internet infrastructure. The power line is the only network that is available almost in any part of the inhabited area, hence can provide extensive coverage for VANET. In this article a scheme is proposed for power lines serve as a medium for transfer of information from RSI to RSI and RSI to Internet gateway. Standard equations are used to noise analysis and quantify the proposed approach as a cost effective deployment of PLC for VANET. Simulation results are provided for further investigations and research. It is evident that PLC with low data rate is suitable for transmission of smart car sensor data as compare to costly high-speed wireless medium.
