Enhanced Junction Selection Mechanism for Routing Protocol in VANETs

Routing in infrastructure less vehicular ad hoc networks is challenging because of the dynamic network, predictable topology, high speed of nodes, and predictable mobility patterns. This paper presents an enhanced routing protocol specifically designed for city environments. It uses vehicular speed and directional density for dynamic junction selection. Simulation results exhibit increased packet delivery ratio while decreased end-to-end delay when compared with state of the art protocols. VANETs are the self-organized networks, composed of mobile nodes capable of communicating in infrastructure less environments.
