A Deep Comprehensive Research Architecture, Characteristics, Challenges, Issues, and Benefits of Routing Protocol for Vehicular Ad-Hoc Networks

VANETs or vehicular ad hoc networks are essential & promising research areas in the ad hoc networks field. The core objective to set up VANET can upgrade road safety & diminish accidents quantity. Routing has been a complex task in VANET as the nodes are highly mobile and consequently, topology alters very quickly. Hence, it is difficult to distribute packets within the minimum period. Contemporary routing protocols cannot meet all demands and issues in VANETs routing. To provide a suitable routing protocol, the crucial factor is to analyze the VANET's protocols for routing. Hence, the paper begins by presenting the fundamental structural design of VANETs to provide a thorough account of several available routing procedures that incorporate their benefits and drawbacks. The paper concludes by providing a summary of the available routing protocols that are used in VANETs.
