Simulation of VANET Routing using A-star Algorithm

Abstract

VANETs are anticipated to prop a colossal spectrum of mobile distributed applications whose scope is from traffic alert dissemination and dynamic route planning to context-aware advertisement and file sharing. The performance of established routing protocols in VANET is very deprived. The main problem with these protocols is their Route Instability in VANET's. The established node-centric view of the routes (i.e., an established path is a succession of nodes between the source and the destination) leads to frequent broken paths in the presence of VANETs' elevated mobility, Consequently, countless packets are dropped, and the overhead due to path repairs or failure notifications considerably increases, leading to low delivery ratios and elevated transmission delays.
