Hybrid MultiHop Routing Mechanism with Intelligent Transportation System architecture for Efficient Routing in VANETs

Abstract

Intelligent Transportation Systems (ITS) are required for efficient vehicle communication in the smart city. The goal of ITS was to provide a broad range of services in transportation, safety, comfort, commercial, mobility, and connectivity applications. In this era, road traffic is a major annoyance. The provision of real-time traffic information to drivers, in conjunction with a navigation system, can enable vehicles to choose the best route. To support ITS, this work proposes a Hybrid Multi-hop Routing Mechanism with Intelligent Transportation System (HMRM-ITS) for efficient communication among vehicles in vehicular ad hoc networks (VANETs). The proposed HMRM-ITS employs the multi-hop routing concept to enable vehicles to improve their driving performance and road safety. Furthermore, the proposed HMRM-ITS allows the transportation organization to communicate instantly between vehicles to Road-Side Units (RSUs), as well as vehicles-traffic servers in an efficient manner. The proposed mechanism enhanced the complete spatial use of a road network by lowering average travel costs of vehicles with a 5-10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup> reduction in traffic overhead over existing mechanisms. Additionally, the HMRM-ITS outperforms existing mechanisms in the form of packet transmission delay and throughput.
