Title DISSEMINATION OF EMERGENCY MESSAGES USING BEACONLESS APPROACH IN INTERNET OF VEHICLES

Author(s) Sidra Nawaz

Abstract The future transportation system demands an intelligent traffic system which aims to create a network of vehicles named Internet of Vehicle (IOV), achieved by connecting groups of vehicles to internet of things (IOT). The abilities of IOV must be utilized efficiently and effectively in order to meet the requirement of current traffic situations. It is mandatory to monitor, manage, and track the connected vehicles in IOV network. During accidental and alarming situation, accurate information delivered in timely manner is considered first priority. For this context, Vehicular Ad Hoc network (VANET) plays a vital role as an emerging technology plays a vital role as an emerging term that is deployed and implemented to reduce the risk of road accidents as well as to improve passenger comfort. In such context, exchange of emergency message through vehicle communication plays an important role for safety related applications. However, dissemination of Emergency Messages (EM) is a major concern. Since it gives rise to several issues such as broadcast storm, unwanted duplication that cause packet loss and poor system’s throughput. For this purpose, BEMD is proposed in which fuzzy logic decision making tool is design that evaluate the rebroadcast probability of a packet for Vehicle to Vehicle communication (V2V). A feedback mechanism is added by utilizing the current available resources in a network in order get acknowledge to make sure the emergency packet is received by the vehicles. BBEMD is compared with past schemes under simulators NS-2.3 and MOVE and BEMD well performs in term of traffic reachability, saved rebroadcast and average service delay.
