“…Lars Wischhof and Hermann Rohling provide a Utility-Based Packet Forwarding and Congestion Control Scheme (UBPFCC) [12] that works on top of IEEE 802.11 MAC protocol and is focused only on non-safety applications. This approach needs the road to be segmented for calculating the message utility metric, thus it cannot be readily applied to VANET.…”

Abstract. Saving human lives on road has become the prime objective of Vehicular Adhoc Network (VANET). VANET-equipped vehicles broadcast periodic safety beacons (single-hop) and event-driven messages (multi-hop) to keep the neighboring vehicles aware of the situation at all times. Well known broadcast communication problems i.e. hidden/exposed nodes, collisions and inherent challenges in VANET e.g. dynamic environment, limited bandwidth, are likely to hinder the exchange of potentially lifesaving information. It is also known that much of the vehicle-to-vehicle broadcast communication will comprise of single-hop periodic safety beacons thus it becomes important to analyze their impact on VANET performance. In this study, extensive simulations were conducted out to appraise the performance of single-hop periodic safety beacons in the context of defined parameters i.e. communication range (CR), beacon generation interval (BGI) and safety beacon size (SBS). The Quality-of-service (QoS) metrics used for the evaluation are packet delivery ratio (PDR), per-node throughput, and end-to-end delay.

“…This has led to a range of recent studies which have focused on developing new congestion protocols more suitable to the challenges of VANETs: dynamic (and fast) network topology changes; dynamic network density changes; network scale problems; peculiar interference issues; limited bandwidth; etc. Indeed, improvements and refinements to VANET-specific congestion control protocols continue to be made [15,14,3,2]. In most of these, however, the analysis of a proposed method relies on simulations for an evaluation of its efficacy.…”

Vehicular ad hoc networks (VANETs), which are a class of Mobile ad hoc networks, have recently been developed as a standard means of communication among moving vehicles. Since VANETs are vital to the safety of the vehicles, the infrastructure, and the humans involved, a deep analysis of their potential behaviours is clearly required. In this paper we provide this analysis through the use of formal verification. Specifically, we formally analyse a specific congestion control protocol for VANETs using a probabilistic model checking technique, and investigate its correctness and effectiveness.

“…The control algorithm uses an application specific utility unction and encodes the quantitative utility information in each transmitted data packet in a transparent way for all users within a local environment [8]. A decentralized algorithm then calculates the "average utility value" of each individual node based on the utility of its data packets and assigns a share of the available data rate proportional to the relative priority.…”

Abstract-Vehicular Ad hoc Networks (VANET) play an important role in future on road Vehicle-to-Vehicle communication systems and related applications like self-organizing, acquiring traffic information using sensors and disseminating it to the nearby vehicles, which are based on broadcast/geocast transmission schemes. It is a challenging task to manage networks in a dynamic environment due to the characteristic of high mobility rate, high relative speed, different driver behaviors and unpredictable link failure occurrences. One of the main criteria in VANETs that has attracted the researchers' consideration is congestion control. Congestion is a major problem all over world, resulting in wastage of valuable time and money. In this paper, we propose multi agent based congestion control scheme, which intelligently acquires the status of the neighboring node information and decides the congestion free path for the safe delivery of packets. Multi agent scheme consists of set of static and mobile agents. Proposed approach guarantees the reliability and timely delivery of messages. Multi agent based scheme exhibits better bandwidth usage and packet delivery ratio and minimizes the latency Index Terms-VANETs, multi agent, latency, bandwidth, congestion control.
