Emergency Response System Using Cellular Networks

Abstract

VANETs is a speci c class of Ad-hoc network.Applications of VANETs varies from safety applications like warning signals, keeping safe distance among vehicles to non-safety ap- plications like traffic congestion, route information, Internet access.Those critical scenario demands faster access of either route information or vehicle information.We focus on esti- mating traffic on the roads so that optimum route can be found. We aim to do it without modifying any infrastructure.Nowadays, almost every person while travelling by road have mobile phones.If location of these phones can be traced then traffic can be estimated.There are many localization techniques which are useful to give accurate location information of any Mobile Node like GPS,dead reckoning,Cellular networks.But,penetration of GPS en- abled phones with active GPS is very less.So, this thesis aims to estimate traffic using cellular networks,which uses in-built infra-structure and is cost e ective.Futhermore,vehicle is routed to the optimum route which is both, less congested and shortest.
