“…The disadvantage of this approach is the high delay and communication overhead. This approach needs high cooperation between the RSU to discover and transfer the congestion notification to the directly connected vehicles (Paranjothi et al, 2018).…”

“…In the location-based routing technique [76,77], the congested route with a sequence of intersections is determined based on statistical techniques. When a link or channel is congested, the RSU sends the information of the congested link or channel to the location server, which returns the congested route with a sequence of intersections.…”

The dynamic nature of vehicular ad hoc network (VANET) induced by frequent topology changes and node mobility, imposes critical challenges for vehicular communications. Aggravated by the high volume of information dissemination among vehicles over limited bandwidth, the topological dynamics of VANET causes congestion in the communication channel, which is the primary cause of problems such as message drop, delay, and degraded quality of service. To mitigate these problems, congestion detection, and control techniques are needed to be incorporated in a vehicular network. Congestion control approaches can be either open-loop or closed loop based on pre-congestion or post congestion strategies. We present a general architecture of vehicular communication in urban and highway environment as well as a state-of-the-art survey of recent congestion detection and control techniques. We also identify the drawbacks of existing approaches and classify them according to different hierarchical schemes. Through an extensive literature review, we recommend solution approaches and future directions for handling congestion in vehicular communications.

“…Ns is a discrete event simulator consisting of many modules including, 1) packet loss model, 2) node deployment model [13,14], and 3) node mobility model for dynamic network topologies to perform the simulation. For a better understanding of the simulation, we provide an overview of Hybrid-Vehcloud [15], a vehicular cloud computing based message dissemination scheme for guaranteed message delivery at high vehicle dense regions like Manhattan where buildings block radio propagation, and Dynamic Fog for Connected Vehicles (DFCV) [16], a dynamic fog computing based message dissemination scheme for rapid transmission of messages and guaranteed message delivery at high vehicle densities. In Hybrid-Vehcloud and DFCV, simulations were conducted to measure the performance of our message dissemination protocol based on the metrics like end-to-end delay of message delivery, probability of message delivery , Packet Loss Ratio (PLR) , and average throughput .…”

Connected and Autonomous Vehicles in Smart Cities Message Dissemination in Connected VehiclesAdvances in connected vehicles based on Vehicular Ad-hoc Networks (VANETs) in recent years have gained significant attention in Intelligent Transport Systems (ITS) in terms of disseminating messages in an efficient manner. VANET uses Dedicated Short Range Communication (DSRC) for disseminating messages between vehicles and between infrastructures. In general, DSRC uses a dedicated 5.9 GHz band for vehicular communication [1]. DSRC has one control channel responsible for sending critical messages like information on road accidents, traffic jams, roadblocks, and six service channels responsible for sending non-critical messages like personal messages. The DSRC bandwidth is composed of eight channels that consist of six 10 MHz service channels for non-critical communications, one 10 MHz control channel for critical communications, and one 5 MHz reserved channel for future uses. As a result, VANET emerged as a promising solution for of ensuring road safety.In a VANET environment, also known as connected vehicular environment, information is disseminated among the vehicles through messages. Two types of messages are disseminated among the vehicles: 1) periodic beacon messages and 2) event-driven messages [2,3]. Periodic beacon messages, also known as Basic Safety Messages (BSMs) include information like vehicle's position, speed, direction, acceleration, braking status, etc. Vehicles typically broadcast BSMs to all neighboring vehicles at an interval of 100ms to 300ms. The objective of broadcasting BSMs is to be aware of the neighboring vehicles. For example, in a high dense vehicular environment like a downtown region, every vehicle receives approximately 1000 BSMs per second. Event-driven messages are generated when a vehicle encounters an event such as accidents, traffic jam, roadworks, etc. [4].Three types of communication are possible in VANETs: 1) Vehicle to Vehicle (V2V) communication, 2) Vehicle to Infrastructure (V2I) communication , and 3) Infrastructure to Vehicle (I2V) communication . [5,6]. V2V and V2I communication depend on DSRC for disseminating messages among the vehicles. V2V communication is used when the vehicles are in the transmission range of each other where vehicles communicate with each other using a multi-hop technique . For example, when a vehicle encounters a dangerous situation such as road accidents, loss of traction, etc., messages are disseminated to the nearby vehicles using a multi-hop technique [7,8]. V2V communication is purely ad-hoc in nature since vehicles communicate with each other directly without any infrastructure. V2V is used for communication among vehicles. V2I is used for communicating with fixed infrastructure and long-distance communication. The components of V2I includes traffic lights, cameras, etc. V2I converts the available infrastructure into a smart infrastructure by incorporating various algorithms that use data exchange between vehicles and infrastructures.
