“…That means, more is the speed of the vehicle (and therefore the cluster to which it belongs), higher will be the priority it will gain over other vehicles which have comparatively lower mobility range. Gupta et al (2015) discuss several CW-based priority assignment schemes which reinforce the validity and genuineness of our proposed protocol. In this methodology, we implement an adaptive MAC mechanism in which the minimum and maximum CW parameters are dynamically tuned based on the mobility of the clustered nodes.…”

Wireless access in vehicular environment employs the IEEE 802.11p/1609.4 standard wherein a multichannel architecture is envisioned to concurrently support both time-sensitive safety-related applications and value-added entertainment services. Although a standard now, the IEEE 802.11p protocol has known shortcomings of not being capable of providing reliable broadcast services. To address this issue, clustering-based enhanced safety message dissemination MAC protocol (CESD-MAC) is proposed in this paper which is an enhancement over the existing IEEE 802.11p/1609.4 protocol. CESD-MAC adopts mobility aware clustering and channel access scheduling. It rules out the concept of switching between the control channel and the service channel as implemented in the legacy standard. Simulation results are presented to verify the effectiveness of the proposed protocol and comparisons are made with the existing IEEE 802.11p MAC. The results demonstrate the superiority of CESD-MAC in terms of reduction of end-to-end delay, and increased throughput, channel utilisation and packet delivery ratio (PDR).Keywords: channel switching; clustering; contention window; DSRC; dedicated short-range communications; IEEE WAVE 1609.4; IEEE 802.11p; MAC; medium access control; multichannel; QoS; quality of service; safety; V2V; vehicle-to-vehicle; VANET; vehicular ad hoc network.Reference to this paper should be made as follows: Gupta, N., Prakash, A. and Tripathi, R.

“…Figures 5 compare the end-to-end delay of the proposed ICDC protocol with those of other protocols under evaluation.. For D-FPAV protocol, the delay limit is below 100 ms for high vehicular density but for sparse scenario, this value surpasses the delay bound limit of 100 ms required for most of the safety applications [8]. DMMAC protocol performs much better than the previously discussed protocols and confines its delay limit much below 100 ms for all vehicular densities and transmission ranges.…”

“…67 • PDR: It is defined as the ratio of data packets received to the total original packet generated by vehicles. 68 • Packet loss: The packet loss happens when the packet does not reach its destination and denotes the ratio of lost packets overall the transmitted packets. 69,70 • Scalability: The VANETs could be a large-scale network.…”

Recently, the fast growth of communication technology has led to the design and implementation of different types of networks in different environments. One of these remarkable networks is vehicular ad hoc network (VANET).The ubiquitous connectivity among vehicles is possible through VANET in the absence of fixed infrastructure. Moreover, it provides safety and comfort to people sitting in the vehicles. In this regard, collecting information from vehicles that are moved constantly is an essential challenge. To develop an efficient method for data collection in the VANET, some parameters must be considered such as data aggregation, latency, packet delivery ratio, packet loss, scalability, security, transmission overhead, and vehicle density. Since data collection has a significant importance in the VANET, the aim of this study is to investigate the existing methods and describe the types of important issues and challenging problems that can be addressed in data collection in the VANET. The data collection techniques are investigated in four primary groups, namely, topology-based, cluster-based, geocast-based, and fog-based.Also, the mentioned parameters are important to compare all of the presented techniques. KEYWORDS communication architecture, data collection, VANET, vehicle-to-vehicle communication, vehicular ad hoc networks | INTRODUCTIONOne of the growing disruptive innovation is the Internet of things (IoT), which allows physical devices to communicate over heterogeneous networks. 1-3 Moreover, one of the IoT applications is vehicular ad hoc network (VANET), 4 which has been developed as a powerful technology aimed at providing safety and comfort to people sitting in the vehicles. 5,6 Moreover, it affords wireless communication among vehicles, and dynamic traffic data is transferred with a high accuracy and low cost. 7,8 The VANET is a module of intelligent transportation systems (ITS) and a subdivision of mobile ad hoc network (MANET). 9,10 Typically, the vehicles are armed with sensing equipment and have a high storage and processing capacity. 11 The unique features of the VANETs include higher node density, instability of wireless channel and limited bandwidth, predictability of vehicular pathway, highly dynamic network topology that change quickly and repeatedly, sufficient energy and resources, and hard delay constraints. 12-14 A large scale of VANET is foreseen to be available in the near future because of the rapid growth of vehicles equipped with communication abilities. 15 The data dissemination and the data collection of vehicles are two significant factors supported by VANET. 16
