Optimization of Emergency Response System Using Cellular Network

Abstract

VANET is a specific class of Ad-hoc network. Applications of VANET vary from safety applications like warning signals, keeping safe distance among vehicles to non-safety applications like traffic congestion, route information, Internet access. Timely help in emergencies like fire, medical etc. is of utmost importance. Response time can be reduced if Emergency Response Vehicle (ERV) can be routed through city roads such that minimal time is taken. We focus on estimating traffic on the roads so that optimum route in terms of time taken can be found. We aim to do it without modifying/adding any infrastructure. Nowadays, almost every person while travelling carries 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 enabled phones with active GPS is very less. So, this paper aims to estimate traffic using cellular networks, which uses in-built infrastructure and is cost effective. From traffic estimates and length of the routes, optimal route is chosen using a unique formula.
