Advances in Position Based Routing Towards ITS Enabled FoG-Oriented VANET–A Survey

摘要: With the rapid growth in connected vehicles and related innovative applications, it is getting keen interest among researchers. Vehicular ad-hoc networks (VANETs) comprise of interconnected with sensing capabilities to exchange traffic, weather emergency information. Intelligent transportation system (ITS) supports better coordination providing reliable services. In VANET, topology dynamic due high mobility vehicles, therefore, existing topology-based schemes are not suitable. this paper, we have explored position based routing (PBR) protocols for VANETs by presenting a taxonomy. The survey papers focused on PBR but further considering city environment along connectivity aware schemes. Moreover, linear programming, genetic algorithms, regression-based also included. To evaluate strengths weaknesses schemes, categorical evaluation different architectures, path strategies, carry-forward strategies presented. Currently, no architecture presented FoG-oriented VANET using parked as guards anchor points or junctions. fill aspiring demand, that can support utilizing road junctions selection. It involves parking area packet transmission. Further, proposed use near junction an option selecting guarding vehicle ITS well. reduces probability extensive carry forward-based communication absence nodes. records at be upgraded neighboring well during beaconing data messages. delivery ratios, end-to-end delay, transmission time, cost. opportunities challenges attract researchers toward research.
