In today's scenario, crime is widely prevalent in every sector of the society. However it has been observed that in most of the cases a vehicle was involved in some or the other way. To make the roads safer and to enhance the public safety on roads, various technologies have been combined which constituents Intelligent Transportation Systems (ITS) network. One example of this field is “Vehicular Ad hoc Networks” (VANETs) which is a subclass of “Mobile Ad hoc Networks” (MANETs). In VANET, automobiles act as mobile nodes and are capable of communicating with one another as well as stationary infrastructure, hence creating an autonomous and dynamic mobile network. This research paper focusses on the proposal of a model for on-road surveillance & security system by integrating various different wireless network technologies/devices, such as Smart phones, WLANs & MANET. The paper also discusses the insecure environment that stirred the need for an efficient surveillance system and how this model approaches to provide a solution. We have used MATLAB tool to simulate and validate the proposed model. The successful implementation of any such system will help in controlling the crime rate as well as it may also aid in providing necessary evidences.
