A novel approach for secured vanet based remote health management system using optimized routing protocols and encryption techniques

Abstract

VANETs (Vehicular Ad-hoc Networks) are a critical component of the newlineIntelligent Transportation System (ITS). VANETs can improve vehicle safety newlineand comfort on highways and in urban areas by eliminating the need for newlineconnections between vehicles and other fixed stations such as Road Side newlineUnits (RSU), Base Station Units (BSU), and so on. One of the most newlinepromising new uses for Information and Communication Technology (ICT) to newlineenhance patient-physician interaction is remote health monitoring via newlineVANET. In recent years, VANET has become popular among users, due to its newlinereliability, low cost, and low maintenance features. The challenges in the newlineVANETs domain come in the form of network detection, congestion control, newlineand management, routing, and security. In VANETs, congestion results in newlinegreater packet loss, lesser throughput, and enhanced packet delay which in newlineturn results in vehicular traffic. Deployment of effective security approaches newlinein VANETS is a demanding issue in today s scenario. When vehicles newlinecommunicate in a network, the messages received by the other vehicles newlineshould be authenticated for validation and acceptance. The vehicles in the newlinenetwork can be identified by their unique details and aids in identifying newlinethemselves in the network. Using their original identities might give a way for newlineattackers in the network. VANETs have a number of special qualities, newlineincluding high mobility, variable network topology, network size, lengthy newlinevehicle distances, regularly shifting vehicle densities, and time constraints. newlineTraditional security and routing solutions are not appropriate for VANETs newlinedue to these unique properties. newline
