“…In [45], a system called TrafficMedia is proposed for querying multimedia clips recorded by vehicles, which store visual and audio information about the traffic conditions. In that system, the vehicles exchange information directly using P2P communications (there is no central node for query processing).…”

In the last years, and thanks to the improvements on computing and communications technologies, wireless networks formed by vehicles (called vehicular networks) have risen as a key topic of interest. In these networks, the vehicles can exchange data with others by using short-range radio signals in order to get useful information related to traffic conditions, road safety, and others. The availability of different types of sensors can be exploited by the vehicles to measure many parameters from their surroundings. These data can then be shared with other drivers who, on the other side, could also explicitly submit queries to retrieve information available in the network. This can be a challenging task, since the data is scattered among the vehicles belonging to the network and the communication links among them have usually a short life due to their constant movement.In this paper, we use the technology of mobile software agents to help to accomplish these tasks, since they have a number of features that are very well suited for their use in mobile environments, such as their autonomy, mobility, and intelligence. Specifically, we analyze the benefits that mobile agents can bring to vehicular networks and the potential difficulties for their adoption. Moreover, we describe a query processing approach based on the use of mobile agent technology. We focus on range queries that retrieve interesting information from the vehicles located within a geographic area and present an extensive experimental evaluation that shows the feasibility and the interest of the proposal.

“…The WiMaC paradigm and the 13 strategies were introduced in a poster paper [6] based on the above three design dimensions. In the WiMac paradigm, since network id's are not known, query processing strategies start with a stage of WiFi dissemination to neighboring peers.…”

In this paper we study querying multimedia data such as video and voice clips in hybrid vehicular networks that consist of vehicles that are capable of both infrastructure-less short-range communication and infrastructure communication. We introduce a set of query processing strategies which differ from each other in terms of push versus pull, whether or not infrastructure communication is utilized, and whether metadata dissemination is separated from multimedia dissemination. We analyze these strategies theoretically and by simulations, and identify the one that is superior to the others.

“…Data management and storage: As outlined above, we can expect to have large scale vehicular networks with millions of vehicles, which will generate huge amounts of distributed data that must be stored in some fashion and distributed across the VANETs. Due to this feature, as pointed out in [38,74], the massive scale, both in the size of network and amount of produced data, as well as the inherent dynamic properties of VANETs, pose new and unique challenges to data management in this setting.…”

Data communication in VANETs: Protocols, applications and challenges

VANETs have emerged as an exciting research and application area. Increasingly vehicles are being equipped with embedded sensors, processing and wireless communication capabilities. This has opened a myriad of possibilities for powerful and potential life-changing applications on safety, efficiency, comfort, public collaboration and participation, while they are on the road. Although, considered as a special case of a Mobile Ad Hoc Network, the high but constrained mobility of vehicles bring new challenges to data communication and application design in VANETs. This is due to their highly dynamic and intermittent connected topology and different application's QoS requirements. In this work, we survey VANETs focusing on their communication and application challenges. In particular, we discuss the protocol stack of this type of network, and provide a qualitative comparison between most common protocols in the literature. We then present a detailed discussion of different categories of VANET applications. Finally, we discuss open research problems to encourage the design of new VANET solutions.
