Integration of Communication Standards in Electrical Vehicle Ad-Hoc Networks for Smartgrid Support

With the motivation toward cutting carbon emissions and achieving oil independency, many countries are embracing Electric Vehicles (EVs). Fitted with wireless sensors and communication devices, EVs have the ability to establish links with their surroundings. This interaction is not only limited to EVs, that is, Vehicle-to-Vehicle (V2V), but can also be Vehicle-to-Grid (V2G) and Vehicle-to-Infrastructure (V2I). This offers a new paradigm in networking and communication in the realm of Internet of Things (IoT). Unlike traditional grids, smartgrids include communication and EVs will have to interact with them as well. Given the wide range of EV and wireless communication technologies, there is a need for standard communication to achieve seamless IoT integration. This paper focuses on the need for standardization of modeling and communication in Electric Vehicle Ad-Hoc Networks (EVANETs) and their interactions with the surrounding such as the grid, smart meter or a smart controller. IEC 61850 substation communication standard, and IEEE 1609 WAVE (Wireless Access in Vehicular Environments) standard are investigated and their integration over IEEE 802.11 is performed. Finally, some privacy issues pertaining to IEEE 1609 are discussed and potential remedies are proposed to mitigate the identified weaknesses while maintaining privacy.
