Vanet: A Future Technology

a Vehicular Ad-Hoc Network or VANET is a technology that has moving vehicles as nodes in a network for creating a mobile network. Vehicular networks are very fast emerging for deploying and developing new and traditional applications. It is characterized by rapidly changing topology, high mobility, and ephemeral, one-time interactions. Our goal is to provide the better algorithm for solution to the inaccurate positioning due to signal loss in GPS locators. We propose our novel work technique in the domain of Navigation in VANET. Recently, GPS handsets have been widely adopted by drivers for navigation. People rely more and more on GPS, and many of them stop checking and printing maps before they depart with a full confidence in GPS. However, due to the sensibility of GPS signals to terrain, vehicles cannot get their locations. To address the issue, we propose a novel Grid-based Onroad localization system, where vehicles with and without accurate GPS signals self-organize into a VANET, exchange location and distance information and help each other to calculate an accurate position for all the vehicles inside the network. And we propose the novel technique to improve our base work, in our technique; the vehicle can find the location even its available inside the tunnel by using Road side unit model (RSU). We aim to create the Street road and simulate the vehicles created on that road considering the traffic using the traffic lights. It gives us idea how the movement of vehicles in a network take place to show the affect traffic on the vehicle and how to tackle with the heavy traffic and ways to ignore the ongoing traffic by taking different routes. It a very good application of VANET which helps to analyses that which route should be taken by the vehicle and how we should complete the journey in minimal time and what will be the optimal path with less traffic in it. Network Simulator 2 (NS2) for short is an open source, Ns2 is a discrete event simulator targeted at networking research. Ns2 provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks, microscopic, multi-model traffic simulation. It allows to simulate how the given traffic demand that is consists of single vehicles moves through a given roadmap.
