Previous studies [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] assumed spectrum availability for VANET.

Different studies have recently emphasized the importance of deploying clustering schemes in Vehicular ad hoc Network (VANET) to overcome challenging problems related to scalability, frequent topology changes, scarcity of spectrum resources, maintaining clusters stability, and rational spectrum management. However, most of these studies addressed the clustering problem using conventional performance metrics while spectrum shortage, and the combination of spectrum trading and VANET architecture have not been tackled so far. Thus, this paper presents a new fuzzy logic based clustering control scheme to support scalability, enhance the stability of the network topology, motivate spectrum owners to share spectrum and provide efficient and cost-effective use of spectrum. Unlike existing studies, our context-aware scheme is based on multi-criteria decision making where fuzzy logic is adopted to rank the multi-attribute candidate nodes for optimizing the selection of cluster heads (CH)s. Criteria related to each candidate node include: received signal strength, speed of vehicle, vehicle location, spectrum price, reachability, and stability of node. Our model performs efficiently, exhibits faster recovery in response to topology changes and enhances the network efficiency life time.

INTRODUCTION owadays, the rapid growth of the world population is indelibly tightly coupled with the massive growth in vehicular communications deployment and application. Recent advances in wireless communication technologies has led to the development of new communication paradigms where vehicles can communicate with each other, i.e. VANET, with the required infrastructure [1]. VANET supports a plethora of safety and non-safety related applications [1,2]. However, these applications require low latency, and high-reliability communication at appropriate overall data rates. Furthermore, a timely update of the network topology is a significant requirement for the operation of safety applications in this network. VANETs pose challenges related to their specific characteristics that distinguish them from other wireless networks. Beside the high mobility, the irregular distribution of nodes leads to frequent VANET partitions, particularly in highway scenarios [1][2][3][4]. Furthermore, the transmission range of vehicles is short, which reduces connectivity [1][2][3][4]. Hence, supporting dynamic data traffic in VANET cannot be guaranteed. Frequent network partitioning results in frequent intermittent connections that may lead to severe packet loss and significant latency [4].In addition, VANETs are non-structured, autonomous, totally decentralized self-configured networks with distributed characteristics nodes [1][2][3][4]. These properties make resource management a challenging problem. Maintaining a global network topology in a centralized entity is essential in order to manage a large-scale VANET in a metropolitan a...

“…This has raised several issues, which are the stability of the cluster, overhead, delay, and disconnect problem. In previous work, [11] proposed centralized clustering-based hybrid vehicular networking architecture (CC-HVNA) that combines both IEEE 802.11p and LTE in VANETs to enhance data dissemination by creating roadside units (RSUs) or BS to elect and form a cluster. This method resulted in improved delay and packet delivery ratio (PDR).…”

The huge development in the number of Vehicle factories have resulted in many people having lost their life due to accident, which has made vehicular Ad-hoc networks (VANETs) hot topic to enable improved communication between vehicles aimed at reducing the loss of life. The main challenge in this area is vehicle mobility, which has direct effect on network stability. Thus, most previous studies that discussed clustering focused on cluster formation, cluster-head selection and the stability of cluster to reduce the impact of mobility in the network, with little attention given to the clusters when passing from base-station to neighbor base-station. Therefore, this study focused on handover problem that occurs after cluster formation and cluster-head election during cluster passing from base station to base station, known as overlapping area. As the cluster in an overlapping area receives two signals from different base stations, the signal arriving at the cluster becomes weak due to interference between two frequencies resulting in loss of cluster information in the overlapping area. In this study, proposed a novel method named Intelligent Cluster-Head (ICH), which is a controller on two clusters that are used to change uplink between clusters to solve the handover problem in the overlapping area. The proposed method was evaluated with VMaSC-1hop method. The proposed method achieved percentage of packet loss up to 0.8%, percentage of packet delivery ratio (PDR) 99%, percentage of number of disconnected links 0.12% and percentage of network efficiency 99% in the cells edge.

Os autores em [Shi et al 2017] propõem uma solução de agrupamento centralizada baseada em uma arquitetura de rede híbrida. Ao usar interfaces IEEE 802.11p e LTE, os veículos podem escolher o modo de comunicação e disseminação de mensagens de alerta para outros grupos da rede através de uma entidade central.…”

“…Embora estudos recentes têm mostrado estratégias ao gerenciamento de eventos em cidades, eles geralmente limitam-se ao tratamento de um evento específico, como por exemplo, inundações [Mousa et al 2016], acidentes veiculares [Chou et al 2017] ou condições de tráfego [Abhishek et al 2016]. Outros trabalhos focam na disseminação de conteúdos de vigilância [Huang et al 2017] ou de colisões [Shi et al 2017], porém em uma abordagem centralizada para a comunicação do evento. Contudo, a própria infraestrutura em cidades inteligentes poderia permitir uma colaboração através de crowdsourcing de veículos na detecção por imagens e disseminação de eventos emergenciais até uma entidade de controle pública externa com capacidade de processamento para reconhecer eventos e tomar as devidas providências de modo a otimizar as ações públicas.…”

Eventos urbanos emergenciais ocorrem de forma aleatória e precisam ser tratados por entidades competentes para manter o bom funcionamento das cidades. Os principais desafios para um tratamento eficiente recaem justamente na aleatoriedade no tempo ou no espaço, e na rapidez e acurácia da comunicação da ocorrência do evento à uma entidade responsável, sendo este último desafio agravado pelo fato desta comunicação depender de intervenção humana. A onipresença de veículos em ambientes urbanos, sua capacidade de comunicação e monitoramento, possibilitam o uso de VANETs como meio de auxílio para disseminação e tratamento destes eventos. Assim, este artigo propõe MINUET, um sistema de monitoramento e disseminação de eventos urbanos, que atua em uma rede veicular não estruturada. Ele é baseado em uma estratégia cooperativa, onde veículos coordenam dinamicamente o monitoramento e a disseminação de múltiplos eventos em tempo real através de agrupamentos. Resultados no NS3 mostram o desempenho do MINUET na detecção, monitoramento e disseminação em tempo real de eventos em zonas urbanas.
