VTrack: Emergency Services for Vehicular Networks with Enhanced Security Using Raspberry Pi

A lot of literature is found in the area of vehicular networks. There are several studies that focus on the security issue. Security and privacy become major issues since the public disclosure of identity and location of vehicle is possible. Not only security but also vehicular networking lacks in applications such as emergency services. This paper presents anonymity of driver or passenger in vehicle, the privacy issue by authenticating the vehicle based on a time-dependent secret. The vehicle communicates with the remote server over a reliable and secure medium. For the purpose of simulation, Raspberry Pi, a Linux-based minicomputer, acts as a vehicle interfaced with a GPS module which gives the position of the vehicle. In the case of emergency, the driver pushes the emergency button on his vehicle and its most recent position is recorded at the server. Server sends this location to ambulance or other emergency services which in turn provides the service at the accident-prone zone with minimum delay. Security of entire communication is enhanced by using AES algorithm along with RSA key exchange technique. The entire implementation is a wireless system with added security and can aid to provide quick emergency services in the accident-prone area. This can save the lives of many people.
