A Data Dissemination Protocol for Vehicles with Temporary Cellular Network Inaccessibility
Puka, Ergys; Herrmann, Peter (Chapter, 2019)The cellular network coverage in sparsely populated and mountainous areas is often patchy. That can be a significant impediment for services based on connections between vehicles and their environment. In this paper, we ... -
A Flexible Way to Dynamically Visualize Spatiotemporal Data in a Geographic Information System
Das, Soma (Master thesis, 2018)In this project thesis, with the development of the dynamic system, we have shown that it is possible to visualize spatiotemporal data flexibly in real-time and which can also be examined from anywhere. The achieved system ... -
A prototype of a precise delay prediction system for buses based on machine learning
Sørensen, Sindre Følling (Master thesis, 2022)Mange busser er i dag koblet til internett, som en del av IoT-trenden for forretning-brukstilfeller. En av brukstilfellene som GNSS-mottagere og internettoppkobling legger til rette for er systemer for forsinkelsesprediksjoner. ... -
An autonomous multi-UAV system for avalanche search
Bryant, Guilhem (Master thesis, 2019)This work aims at theorizing and designing a multi-UAV system for localizing avalanche victims in an optimal way. Using UAVs instead of human rescuers for victim search offers several advantages such as their high velocity, ... -
Data Dissemination for Vehicles in Temporary Cellular Network Dead Spots
Puka, Ergys; Herrmann, Peter (Journal article, 2019)The cellular network coverage in sparsely populated and mountainous areas is often patchy. That can be a significant impediment for services based on connections between vehicles and their environment. In this paper, we ... -
Developing a Testbed for VANET Protocols using Drones
Groven, Halvor (Master thesis, 2021)Antallet biler i trafikken øker hver dag. Dette resulterer i voksende utfordringer relatert til økt trafikkbelastning- og sikkerhet, og ny teknologi og nye løsninger må utvikles for å adressere disse utfordringene. I ... -
Dynamic Computation of Connectivity Data
Meyer, Jon Arild Ekberg (Master thesis, 2019)Ytelsen til den underliggende kommunikasjonsteknologien spiller en viktig rolle i Vehicular Networks (VNs). Strenge krav må oppfylles for å sikre nødvendig sikkerhet og robusthet, i tillegg til å gi brukertilfredshet. I ... -
Evaluating the Effect of Satellite Communication on the Data Dissemination Protocol CAMFlooP in Areas with Limited Cellular Connectivity
Johannessen, Jakob Lund (Master thesis, 2023)Dagens mobile nett har flere soner uten dekning, hvilket er synlig på sider som nperf.com. Biler som befinner seg i disse sonene kan derimot kommunisere med hverandre med lokale nettverk de oppretter. På denne måten kan ... -
Hybrid Context-aware Message Flooding for Dead Spot Mitigation in V2I Communication
Puka, Ergys; Herrmann, Peter; Taherkordi, Amirhosein (Peer reviewed; Journal article, 2020)An often overlooked practical problem in Intelligent Transportation Systems (ITS) is the presence of areas without cellular network connectivity, so-called dead spots, which aggravates the communication between vehicles ... -
Machine Learning-based Uptime-Prediction for Battery-friendly Passenger Information Displays
Herrmann, Peter; Puka, Ergys; Skoglund, Tor Rune (Chapter, 2020)Personal Information Displays (PID) at bus stops help making the usage of public transport more attractive. If no electric grid is nearby, however, the installation of PIDs is very expensive due to the high wiring costs. ... -
Message Forwarding between Vehicles in Dead Spots - English
Jakobsen, Rakel Helèn (Master thesis, 2018)The project for this master thesis aimed to study the concept of vehicle-to-vehicle communication in places with no or little Internet connection, so called dead spots. Collecting traffic information along the road is ... -
Mitigating Dead Spots in Cellular Networks with the Hybrid Communication Protocol CAMFLOOP
Puka, Ergys; Herrmann, Peter (Chapter, 2021)The interaction between vehicles and the external infrastructure usually relies on the availability of cellular networks. Large sparsely populated regions, however, contain often extended areas with missing cellular network ... -
Utilizing Connectivity Maps to Accelerate V2I Communication in Cellular Network Dead Spots
Meyer, Jon Arild Ekberg; Puka, Ergys; Herrmann, Peter (Peer reviewed; Journal article, 2020)On many roads in rural and mountainous areas, the cellular network connectivity is intermittent and dead spots, i.e., zones without any coverage, are frequent. In previous work, we developed a data dissemination protocol ...
