“…Cenerario et al [13] constructed an event-related information exchange/sharing protocol of the VSNs. Relying on the short interactions amongst the vehicles to exchange/share information about relevant events, they proposed the concept of encounter probability, in order to decide when an information re-diffusion becomes feasible.…”

Given the escalating population across the globe, it has become paramount to construct smart cities, aiming for improving the management of urban flows relying on efficient information and communication technologies (ICT). Vehicular sensing networks (VSNs) play a critical role in maintaining the efficient operation of smart cities. Naturally, there are numerous challenges to be solved before the wide-spread introduction of VSNs, including the conception of an accurate topological analysis method as well as of a beneficial cooperation mechanism during the process of city-wide information sharing. Hence, in this paper, we construct a VSNs-aided smart city model and appraise a range of intelligent applications in terms of both public services as well as of urban flow management. Then, the information source selection algorithm of a complex network and a reinforcement learning based city information sharing mechanism are considered, complemented by a range of open challenges.

“…The objective of this design is to reduce tracking error and improve the robustness and performance of cooperative vehicle safety systems under different traffic conditions [1]. The concept of Encounter Probability (an estimation of the likelihood that a vehicle will meet an event) to determine whether an event is relevant enough to be rediffused or not [4] discussed. ACPN provides the conditional vehicle anonymity for privacy preservation with traceability for the non-repudiation, in case that malicious vehicles abuse anonymous authentication techniques to achieve malicious attacks [10].…”

A Vehicular Ad-hoc Network (VANET) consists of the vehicle to vehicle and vehicle to roadside communication. Growing the density of the vehicles on the road causes flooding while transferring packets from a source to one or multiple destinations over a VANET. However, increasing vehicles on road may causes a problem such as redundancy, congestion, collision and increasing delay though receiving emergency warnings. As long as reliable and proficient multi-hop broadcast in vehicular ad hoc networks is challenging one. In the proposed system commence a new protocol which uses the character of elegant route establishment and selection method for transfer information to the destination (dst) with minimum redundancy, delay and highest bits per second delivery. In some environment vehicles are deployed in a dense manner, and it can move at a high speed. Adjacent Access Points (APs) on the road find out route information from their past report gatherings which use a fuzzy logic to select routing conclusion. This approach consists of isolating the whole network area into clusters. Based on which an optimized route is chosen using the input parameters as vehicle density, distance from the adjacent AP, vehicle mobility, receiving signal strength and delay should be jointly measured in the relay node selection. Though, these computation conflicts with each other depend on vehicle mobility. Hence, we employ fuzzy logic to handle this imprecise information to select forwarding vehicles by mutually taking into account of vehicle distance (d), mobility (v) and Receiving Signal Strength (RSS). The selected vehicle can provide an assure data forwarding with a high competence. The performance of the proposed scheme is evaluated on the metrics such as end-to-end delay, packet delivery ratio by varying vehicle speed, and density of vehicles.

“…The detailed classification results have been shown in Figure 6. For example, a content-based dissemination protocol for VANETs is proposed in [58], which defines an eventrelated degree parameter to indicate the encounter probability between vehicle node and event. The last broadcast vehicle node selects the neighbor node that has the highest event-related degree value to be the next rebroadcast node.…”

With the continuously increasing number of vehicles, particularly in cities, there are more and more abnormal traffic events occurring on road, which easily cause road congestion. In vehicular sensor networks (VSNs), with the intervehicle cooperative communication, vehicle nodes can detect the abnormal traffic events and disseminate the related information to the interesting vehicles or persons. This paper gives out a survey of the abnormal traffic information detection and transmission mechanisms in VSNs. Firstly, we overview the origin, characteristic, and application of VSNs. Meanwhile, the definition and features of traffic abnormal information are also introduced and presented. Then, we put more energy on elaborating the existing information detection and transmission mechanisms based on VSNs. Finally, the challenges and problems are discussed.
