Context-aware Hybrid Data Dissemination in Vehicular Networks available in PDF, EPUB and Kindle. This work presents the development of the Context-Aware Hybrid Data Dissemination protocol for vehicular networks. The importance of developing vehicular networking data dissemination protocols is exemplified by the recent announcement by the U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration (NHTSA) to enable vehicle-to-vehicle (V2V) communication technology. With emphasis on safety, other useful applications of V2V communication include but are not limited to traffic and routing, weather, construction and road hazard alerts, as well as advertisement and entertainment. The core of V2V communication relies on the efficient dispersion of relevant data through wireless broadcast protocols for these varied applications. The challenges of vehicular networks demand an adaptive broadcast protocol capable of handling diverse applications. This research work illustrates the design of a wireless broadcast protocol that is context-aware and adaptive to vehicular environments taking into consideration vehicle density, road topology, and type of data to be disseminated. The context-aware hybrid data dissemination scheme combines store-and-forward and multi-hop broadcasts, capitalizing on the strengths of both these categories and mitigates the weaknesses to deliver data with maximum efficiency to a widest possible reach. This protocol is designed to work in both urban and highway mobility models. The behavior and performance of the hybrid data dissemination scheme is studied by varying the broadcast zone radius, aggregation ratio, data message size and frequency of the broadcast messages. Optimal parameters are determined and the protocol is then formulated to become adaptive to node density by keeping the field size constant and increasing the number of nodes. Adding message priority levels to propagate safety messages faster and farther than non-safety related messages is the next context we add to our adaptive protocol. We dynamically set the broadcast region to use multi-hop which has lower latency to propagate safety-related messages. Extensive simulation results have been obtained using realistic vehicular network scenarios. Results show that Context-Aware Hybrid Data Dissemination Protocol benefits from the low latency characteristics of multi-hop broadcast and low bandwidth consumption of store-and-forward. The protocol is adaptive to both urban and highway mobility models.

Download and read online ebook Development of Smart Context-Aware Services for Cargo Transportation write by Dalė Dzemydienė. This book was released on 2022-09-02. Development of Smart Context-Aware Services for Cargo Transportation available in PDF, EPUB and Kindle. With a focus on cargo transportation, this book addresses the development of approaches intended to secure an infrastructure of smart services to support the adaptive implementation of online multi-modal freight transport management processes. It discusses the development of multi-criteria decision-making components and their integration into the multi-layered computer-based information management of intelligent systems. Through detailed descriptions of various components of intelligent transport management systems, the book demonstrates how to develop the services needed in the right place and at the right time, and how to properly adapt to user needs, making necessary interventions to ensure the safety of the transportation process. Further, it describes the main ways to increase the autonomy and efficiency of user-vehicle interaction and shows how Information and Communications Technology (ICT) structural support for current and past situations in AI-based systems can help to anticipate future developments in freight transportation.

Context-Aware Communication in Large Scale Vehicular Ad-Hoc Networks available in PDF, EPUB and Kindle. Rapid advancements in embedded technology enable vehicles to become equipped with embedded on-board computation and wireless communication capabilities. Intelligent transportation systems (ITS) is an emerging research field that demands efficient delivery of information between vehicles for the creation of useful and usable telematic applications operating in nomadic large-scale environments. Some interesting inter-vehicular applications made possible by this technology include accident avoidance, incident notification, congestion monitoring and parking space allocation. For these types of applications it is crucial that the peers receive the \textit{right information at the right time and the right place} to make informed decisions. However, due to the ephemeral, highly dynamic and mobile nature of the vehicular networks we face four major challenges: (1) how to identify what information is relevant to take actions or make decisions, (2) how to disseminate the relevant information to the interested peers efficiently, (3) how to coordinate with other peers and (4) last but not the least, how to compare the effectiveness of different algorithms and protocols.
