A novel selective cross layer based routing scheme using ACO method for vehicular networks

Abstract Internet of Vehicles (IoVs) as one of the developing paradigm in the current scenario intends to present a plenty of inventive applications and services. These developing applications force to attain a specific quality of service (QoS) requirements for Vehicle Ad-Hoc Networks (VANETs). Because of high node density and substantial mobility the complexity of VANET increases tremendously, which results the process of routing, security and QoS challenging. This yields an emerging need to design a more productive and intellectual routing protocol in VANET. In this paper we propose a novel selective cross layer design based Ant Colony Optimized Ad-Hoc On Demand Distance Vector (ACO-AODV) routing protocol. The cross-layer design proposed in this work selectively optimizes the information acquired from Application (APP) layer, Transport layer; physical layer and the Media Access Control (MAC) layer in the networks. We used the advantage of ACO to resolve the route selection issue and Particle Swarm Optimization (PSO)based MAC scheduling mechanism for slot assignment during data transmission. Simulation results & Comparisons are presented to show the significance of the proposed routing protocol with improved QoS.
