A survey on multi-constrained optimal path selection schemes and authentication schemes for VANET

Vehicular ad hoc networks (VANETs) are intended to get better driver safety, avoid collisions, and offer traffic optimization. Recent years have behold an increasing interest in the security schemes for VANETs as well as improve multi-constrained optimal path selection for finding feasible routes. However, there are still several issues to be convey prior to such authentication mechanisms can be voluntarily and extensively used in real-life deployments. In this paper, we examine several authentication schemes and multi-constrained optimal path selection based on certain criteria like Qos constraints.
