“…The preliminary intention of VANET communication is to provide safety to the VANET users. The safety enhancement applications aim to assist drivers in handling unpredictable events or hazardous situations by broadcasting the safety messages such as an accident or collision warning, and weather conditions such as icy and foggy roads [3]. In a safety environment, a vehicle rapidly broadcasts safety information to other vehicles in the dangerous zone using dedicated RSUs.…”

Vehicular Ad Hoc Network (VANET ) is a special type of communication network that promises wide applications ranging from road safety to driving comfort. The rich applications enhance the safety and comfort of travelers by establishing a cooperative communication among the vehicles. To increase communication efficiency this work proposes an Ant Colony Optimization based Quality of Service Routing protocol(ACORP) for VANETs that aims to enhance the road safety and travel convenience in VANETs.

“…Therefore, promising a stable and efficient QoS routing over VANETs is essential in real time vehicular communications. Efficient and reliable QoS based routing protocols [5] [6] are crucial to forward data packets within the required QoS constraints in the targeted regions and also to be adapting well to various applications The work in [7] determines the key factors that affect the warning message dissemination. Another work in [8] provides a brief study of hybrid adaptive beaconing mechanisms presented for VANETs.…”

Vehicular Ad Hoc Network (VANET) communication promises a vast array of applications ranging from road safety and driving comfort. Safety message broadcasting plays a significant role in highway safety in which the safety alert messages have to be delivered immediately to the vehicles located in the risk boundary area. Most of the current research attempt to select optimal relayer for safety message rebroadcasting. However, relayer selection models are not efficient, especially in a high-density VANET, as they cause a high delay in safety message delivery and lead to multiple accidents at the incident spot. To avert these issues, this work proposes a QoS Routing Protocol (QoRP) that aims to enhance the road safety in both sparse and dense VANETs.

“…The same authors have also designed a movement prediction–based routing (MOPR) in which each node calculates the link lifetime for each neighboring node before selecting the next hop for packet dissemination . Shelly and Babu proposed a reliable protocol that ensures the improvement of GPSR. The protocol considers data forwarding according to the higher probability of reliable links.…”

Vehicular ad hoc networks (VANETs) have gained incredible attention because of their applications in safety, commercial uses, and traffic management. However, the dynamic topology changes caused by the high speed of vehicles raise many challenges for the effective data dissemination in vehicular applications.In this paper, with the objective to solve the problem of frequent disconnection during data delivery, we propose a novel, intelligent forwarding-based stable and reliable data dissemination scheme. First, link stability is described mathematically, by which vehicle chooses the next forwarding node. Then, a greedy algorithm is presented to transmit the data from source to destination. A separate recovery algorithm is also designed to resolve the intermediate link breakage problem. The performance of the proposed method is analyzed by performing extensive network and traffic simulations with respect to various indexes such as latency, packet delivery ratio (PDR), and throughput. Compared with the state-of-the-art protocols, the proposed method under varying density improves the average PDR and throughput by 31.55% and 25.30%, respectively. KEYWORDS greedy forwarding, link duration, stability, VANET INTRODUCTIONVehicular ad hoc networks (VANETs) have emerged as an integral part of intelligent transportation system (ITS) for effective data transmission in the past few years. The inter-vehicle and roadside communication networks of VANETs have gained importance because of its usage in many applications all over the world. Road safety, traffic control, and infotainment are the promising applications of vehicular communication. Vehicle and roadside unit (RSU) act as intelligent devices for data collection from the environment by using effective routing protocols and then transmitting the data to other devices connected to the Internet and cloud. VANETs support two distinct communication scenarios: vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. In V2V, vehicles exchange information with one another, and in V2I, vehicles uses information provided by nearest roadside components. The architecture of vehicular communication is shown in Figure 1. The amendment to the IEEE 802.11 standard, ie, IEEE 802.11p, pertains to vehicular communications. 1 The standard comprises the Physical (PHY) and Media Access Control (MAC) protocols for Wireless Access in Vehicular Environment (WAVE). 2 The higher layer protocols are built on the IEEE 1609 standard. In 2003, Federal Communications Commission (FCC) proposed a dedicated short-range communications (DSRC) system with the allocation of 75 MHz of spec-Int J Commun Syst. 2019;32:e3869. wileyonlinelibrary.com/journal/dac FIGURE 1 Vehicular ad hoc network architecture.
