Road Accident Prevention with Instant Emergency Warning Message Dissemination in Vehicular Ad-Hoc Network

摘要: A Road Accident Prevention (RAP) scheme based on Vehicular Backbone Network (VBN) structure is proposed in this paper for Ad-hoc (VANET). The RAP attempts to prevent vehicles from highway road traffic accidents and thereby reduces death injury rates. Once the possibility of an emergency situation (i.e. accident) predicted advance, instantly initiates a accident prevention scheme. constitutes following activities: (i) Side Unit (RSU) constructs Prediction Report (PR) status roads, (ii) RSU generates Emergency Warning Message (EWM) abnormal PR, (iii) forms VBN (iv) disseminates EWM that holds high Risk Factor (RF) travels High Zone (HRZ). These might reside either within RSU’s coverage area or outside (reached using structure). improves performance dissemination terms increase notification decrease end-to-end delay. also infrastructure cost (number RSUs) by formulating deploying structure. with 19 percent delay 14.38 vehicle density 160 vehicles. It proved simulation experiment promising 4-lane roads.
