Providing Accident Detection in VehicularNetworks through OBD-II Devices and
Android-based Smart phonesAbstract:
The widespread adoption of mobile telephony has remarkably improved interpersonal
communications in our society. Nowadays mobile phones resemble small multifunction
computers, being characterized by a CPU power and RAM size similar to that of laptop
computers available only a few years ago. The future trend is that more and more users own
these intelligent mobile terminals, and that their main use gradually shifts towards functionalities
including web surfing, social networking, multimedia streaming, online games, domestic
applications, and so on. Under these premises, it is possible to introduce novel services using
smart phones in many different contexts. At the same time, the automobile industry is
undergoing a major strategically shift towards more ecological and secure vehicles, introducing
also new vehicular services such as eco driving support and Internet access.
Existing System:
In existing system there is no on board diagnostics available for vehicles.
Proposed System:
The increasing activity in the Intelligent Transportation Systems area faces a strong
limitation: the slow pace at which the automotive industry is making cars "smarter". On the
contrary, the smart phone industry is advancing quickly. Existing smart phones are endowed
with multiple wireless interfaces and high computational power, being able to perform a wide
variety of tasks. By combining smart phones with existing vehicles through an appropriate
interface we are able to move closer to the smart vehicle paradigm, offering the user new
functionalities and services when driving. In this paper we propose an Android based application
that monitors the vehicle through an On Board Diagnostics (OBD-II) interface, the OBD has a
microcontroller with sensors such as fuel level, engine temperature, and an accelerometer. The
