TAD-HOC Routing Protocol for Efficient VANET and Infrastructure-Oriented Communication Network

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.

A Survey on Junction Selection based Routing Protocols for VANETs

“…The node uses an intermediate node for exchanging information with the nodes that are beyond its transmission range [4], [10], [27]. Due to self-organizing nature of VANET, its structural design categorized into three kinds: i) Pure adhoc networks ii) Pure cellular wireless local area network iii) Hybrid networks [12], [13].…”

“…The highly mobile vehicular nodes frequently alter the network topological connections. The frequent topology changes cause network fragmentation [13]. In this kind of architecture, the network fragmentation due to high mobility makes routing of data more challenging [20], [28].…”

“…These include accident avoidance, facilitating internet access inside vehicles, monitoring traffic flow regulations, locating parking lots, finding restaurants, and gas stations [29]. Inside vehicles, it is also useful in managing entertainment applications like playing games, watching movies, and listening music [10], [13].…”

“…The existing literature provides topology-based routing protocols and position-based routing protocols [3]. Topologies based routing protocols are ineffective in VANETs because of intermittent connectivity [13]. The position-based routing category is considered more effective in VANETs [10].…”

Improving AODV Routing Protocol for Image Transmission Over Mobile Video Sensor Networks

“…Based on the structure of the MANET, routing protocols are classified into two types: proactive and reactive protocols [9]. In the proactive routing protocols, links between each pair of the nodes in the network are already established.…”
