Abstract
Most wireless sensor networks (WSN) consist of gateways and also sensor nodes that operate devices that have limited resources, and to introduce effective communication it is necessary to choose an application protocol that allows data to be transmitted more securely and with low bandwidth and energy consumption. For V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) systems, certain protocols cannot guarantee solid security with low energy consumption. This paper will identify the issues of two main application layer protocols used for Vehicular and infrastructure communication, Among the most well-known protocols in the automotive industry is Message Queuing Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP), such as review our solution using elliptic curve cryptography into the two protocols to fix privacy and communication problems with low energy consumption.
