This article presents the results of research on the acceleration of data processing in the construction routing in dynamic DTN, realized through the devices established in moving objects and connected by means of Wi-Fi. The routes are constructed based on the prehistory of the movement of objects, which is stored in the database in the csv format. This database has a large volume and contains unnecessary and incorrect information. The article shows the possibility of speeding up the process of constructing routes using data precleaning. Reducing data volume is proposed by constructing an enlarged grid on the object movement map. This article also demonstrates the use of fuzzy logic and graph theory for constructing routes.

Vehicular ad hoc networks (VANETs) are a special case of mobile ad hoc networks (MANETs). The distinctive characteristics of VANETs include high-speed vehicular nodes and significant variability in node density. Collecting data from VANETs is important in monitoring, controlling, and managing road traffic. However, efficient collection of the needed data is challenging because vehicles are continuously moving and generating a significant amount of events and data. The focus of this paper is on vehicle data collection using 3G/LTE. Initially, a comparison of proactive and reactive data collection schemes is conducted using simulation. The results show that proactive schemes produce the lowest delay and bandwidth usage but the highest loss ratio. To efficiently use the available bandwidth, an adaptive data collection scheme is developed and described. This adaptive data collection scheme is based on a proactive scheme using variable polling periods depending on the vehicle positions in the network and travel time to provide accurate traffic and travel time information to the Traffic Management Center (TMC). Simulation results, using taxi traces in Qatar, show that the proposed algorithm consumes an acceptable amount of megabytes (≈31 MB) per month when the basic polling interval is set to 10 s. Furthermore, traffic simulation results demonstrate that the proposed scheme has a minimum impact on delay and travel time estimates (relative error less than 2.5%), but can produce significant degradations in fuel consumption and emission estimates if computations are made at the TMC (relative error greater than 28% and 65%, respectively). These errors can be eliminated if computations are done on the vehicle.Index Terms-Mobile communication, data collection, automotive applications, intelligent transportation systems, wireless networks, traffic information, data aggregation, travel time estimation, vehicle emission estimates. 1524-9050

Abstract-Vehicular ad hoc networks allow connected vehicles to exchange and share information in order to improve traffic efficiency and safety as well as to provide infotainment functions. In order to cope with the challenging network conditions of the vehicular domain (e.g., intermittent connectivity), a disruptiontolerant networking architecture is suitable. In contrast to pushbased communications (e.g, cooperative awareness messages) used in many proposed vehicular applications, we focus on a query-response model for requesting sensor information. Of particular interest to us is the question how vehicular queries can be efficiently routed to a destination area in such challenged environments, and, more importantly, how the response can be routed back to a moving query originator. We therefore present Breadcrumb Geocast Routing (BGR), a novel disruptiontolerant georouting protocol based on a trail of breadcrumbs left by the query originator. As an overlay protocol, BGR can be used on top of different georouting mechanisms, providing an efficient means to address moving originators. We study the influence of parameters, e.g., breadcrumb size and distance, and prove the effectiveness of the proposed solution in an extensive experimental evaluation, showing that BGR achieves significantly higher delivery rates compared to traditional geocast approaches, while avoiding up to 97 % of the traffic overhead of Epidemic and PRoPHET routing.
