Framework for Ease Maneuver of On Road Emergency Vehicles: Using Mobile Sink

ABSTRACT:In order to make timely and correct decisions and to avoid potential accidents, moving vehicles on the road need to acquire real time traffic flow and road information directly from WSN with the help of telematics services. The concept proposed in this paper involves the use of multiple metric to promote emergency vehicle an ease of transport during their crucial hours of time. This includes a proposal of a practical and scalable approach for point-topoint routing in wireless sensor nets which aims at providing the shortest path for emergency vehicles to save time, and to enable a robust paradigm for sensor network to change the primary path of the emergency vehicle dynamically. In addition to these, this paper also indulges in the proposal of analysing real-time traffic flow parameters using image sensors and controlling the congestion on priority basis.

INTRODUCTION Traffic management being a vast domain, WSN can be applied to gather information about the incoming flow of traffic, traffic load on a particular road, traffic load at particular period of time (peak hours) and in vehicle prioritization. Because of the recent developments in wireless networks and multifunctional sensors with digital processing, power supply and communication capabilities, WSN are being largely deployed in physical environments for fine-grain monitoring in different classes of applications [1] The proposal of an adaptive and dynamic traffic intersection system include first finding of shortest path for the emergency vehicle to reach its nearby health care zone from the accident area usinga scalable a point-to-point routing schemecalled Beacon Vector Routing or BVR method. The second module is to find a better dynamic path arrangement for emergency vehicle, because the traffic status is changed dynamically. To achieve a fault tolerant and low latency algorithm, called PEQ (Periodic, Event-Driven and Query-Based Protocol) is employed. The main purpose to adopt this algorithm than any other existing routing algorithm is that PEQuse ordinary motes, with no special hardware and a simple processing at each node by using the hop level as the main information to minimize data transmission. The next part of this paper deals with an adaptive traffic intersection system where traffic light of one intersection communicates with the traffic light of the next neighbouring intersections and controlling the congestio
