Abstract
Intelligent Transportation System (ITS) is a critical factor for Vehicular Ad hoc Networks (VANET). Even though VANET belongs to the class of Mobile Ad hoc Network (MANET), none of the MANET routing protocol applies to VANET. VANET network is dynamic, due to increased vehicle speed and mobility. Vehicle mobility of VANET affects conventional routing algorithm performance, which deals with the dynamicity of the network node. The evaluation of the existing research stated that Ad hoc On-Demand Distance Vector (AODV) is an effective MANET protocol to adopt network changes for significant resource utilization and also provides effective adaptation in the network change. Due to the effective performance of the AODV protocol, it is considered as an effective routing protocol for VANET. This paper proposed an ad hoc TROPHY (TAD-HOC) routing protocol for the VANET network for increasing efficiency and effective resource utilization of the network. To improve the overall performance, ad hoc network is combined with Trustworthy VANET ROuting with grouP autHentication keYs (TROPHY) protocol. The proposed TAD-HOC protocol transmits data based on time demand in the VANET network with the desired authentication. Results of the proposed approach show the increased performance of the VANET network with packet delay, transmission range, and end-to-end delay. The comparative analysis of the proposed approach with I-AODV, AODV-R, and AODV-L shows that the proposed TAD-HOC exhibited effective performance.
Highlights
Vehicular Ad hoc Networks (VANETs) belongs to the class of ad hoc network that inherits Mobile Ad hoc network characteristics (MANETs) with a fewer change in performance [1, 2]. e VANET offers wireless communication through a connection of hundreds or thousands of nodes
We proposed the TAD-HOC routing protocol design for VANET. e proposed architecture combines ad hoc and Trustworthy VANET ROuting with grouP autHentication keYs (TROPHY) protocol applied in Wireless Access in VehicularEnvironment (WAVE) architecture for the effective performance of the routing network. e primary step involved in this paper is the construction of a VANET network that transmits data in an ad hoc manner
TAD-HOC protocol transmits data based on time demand in the VANET network with the desired authentication. e main contributions of this paper are the following: (i) Review of existing protocols for VANET and comparison with the new proposed TAD-HOC routing protocol (ii) Performance analysis of the proposed TAD-HOC network, which helps increase the performance of the VANET network with packet delay, transmission range, and end-to-end delay
Summary
Vehicular Ad hoc Networks (VANETs) belongs to the class of ad hoc network that inherits Mobile Ad hoc network characteristics (MANETs) with a fewer change in performance [1, 2]. e VANET offers wireless communication through a connection of hundreds or thousands of nodes. A further variety of safety applications are adopted intrinsically in the VANET network for human-lives saving. Is VANET network is subjected to vast topology changes and increased node mobility [4, 15]. VANET network belongs to the category of an ad hoc network environment, which is composed of vast distinct vehicles, such as trucks, buses, motorcycles, and cars. In this VANET network, nodes are considered as vehicles along with the roadside unit. In VANET, it is important to consider network connectivity and routing efficiency with the characterization of link disconnection and change in a network topology. Besides VANET safety application, nonsafety applications [24] are adopted for contextualized information sharing between passengers and entertainment applications for interaction through the internet or among other devices [9, 25]
