A Comprehensive Review of Nature-inspired Algorithms for Internet of Vehicles

Internet of Vehicles is an integration of VANETs and IoT to enhance the proficiency of VANETs by incorporating smartness. Due to its numerous characteristics, it has gained lot of attention among researchers. Nature inspired algorithms are inspired from nature's strategy to cope with all day to day problems. In this review, main focus is to explore nature-inspired algorithms as these are quite beneficial in optimization. Nature-inspired algorithms are capable to deal with all kind of complex problems so in this paper, its applicability in internet of vehicles has been explored. In internet of vehicles, nature -inspired algorithms can be applied mainly in two aspects-Routing and Security. It aims to optimize all routing issues among vehicles as delay and timely information cannot be tolerated in real-time applications. On the other hand, security is of major concern in vehicular networks thus, nature inspired algorithms are able to prevent various attacks. In this paper, we have reviewed both routing and security applications of nature-inspired algorithms.
