Aim

           The main aim of this project is providing the secure communication between the two cars in VANET environment.

Synopsis

          The Internet of vehicles (IoV) provides new opportunities for the coordination of vehicles for enhancing safety and transportation performance. Vehicles can be coordinated for avoiding collisions by communicating their positions when near to each other, in which the information flow is indexed by their geographical positions or the ones in road maps. Vehicles can also be coordinated to ameliorate traffic jams by sharing their locations and destinations. Vehicles can apply optimization algorithms to reduce the overuse of certain streets without excessively enlarging the paths. In this way, traveling time can be reduced. However, IoV also brings security challenges, such as keeping safe from virtual hijacking. In particular, vehicles should detect and isolate the hijacked vehicles ignoring their communications. The current work presents a technique for enhancing security by applying certain prioritization rules, using digital certificates, and applying trust and reputation policies for detecting hijacked vehicles. We tested the proposed approach with a novel agent-based simulator about security in IoT for vehicle-to-vehicle (V2V) communications (ABS-SecIoTV2V). The experiments focused on the scenario of avoidance of collisions with hijacked vehicles misinforming other vehicles. The results showed that the current approach increased the average speed of vehicles with a 64.2% when these are giving way to other vehicles in a crossing by means of IoT.

Proposed System

          We are proposing a emergency message in VANET environment. In this system messages are broadcasted only in their region of interest so that delivery latency will be decreased. In Proposed system if a vehicle in the environment detects a dangerous event, it immediately generates and broadcasts emergency message to vehicles in region of interest, so that the vehicles can take preventive measures to avoid accident. Emergency Messages will be broadcast to vehicles which are needed to take action to avoid accident.  And we proposed the security function for this project while message communication. When the messages send to one user \to another user we should encode the content inside the message and compare the encoded values. If the encoded values are same that user recognized the authorized user and they will get the trust vales, otherwise that user recognized as a unauthorized user they will get a minus trust values.

Advantages

• This work presented an intelligent transportation system to avoiding congestions.
• vehicles are modeled as agents, and V2V communications are simulated as social interactions among agents.
