On the cleansing and inspection of GPS ephemeris data 2000–2016
Archived GPS ephemeris data for years 2000-2016 is investigated by cleansing and precision measures. The goal of this work was twofold: (1) to reveal and remove incorrect ephemeris data so that the cleansed data is as close to the real broadcasted data as possible, and (2) to analyse the quality of...
SensIs - Underwater acoustic network for ice-monitoring
Routing for low latency underwater acoustic network-communication is investigated. The application is monitoring of ice-threats to offshore operations in the Arctic - to provide warnings that enable operators to react to such threats. The scenario produces relatively high traffic load, and the...
On the use of Information-Carrying based Route Protocol in real UWSN deployments with high traffic load
Underwater networks that are designed to carry high-priority data at a relatively high traffic load should employ network protocols that emphasize low delay and adequate reliability at the expense of energy. ICRP (Information-Carrying based Routing Protocol), originally proposed by Wei Liang et al...
Ocean space surveillance system - OSS
Ocean space surveillance system - OSS
OSS is a real-time supervising concept for marine operations and management based on data assimilation and integrated measurements and models. OSS is composed of an underwater sensor network, communication links to computers running ocean models, computer ocean models and a data assimilation tool...
Linking Acoustic Communications and Network Performance: Integration and Experimentation of an Underwater Acoustic Network
Underwater acoustic networks (UANs) are an emerging technology for a number of oceanic applications, ranging from oceanographic data collection to surveillance applications. However, their reliable usage in the field is still an open research problem, due to the challenges posed by the oceanic...
Efficiency of Opportunistic Spectrum Sensing by Sequential Change Detection in Cognitive Radio
A critical point in cognitive radio spectrum sensing is the ability to detect presence and absence of primary users as fast as possible at very low SNR. In this paper, sequential power detection by cumulative sum and recursive generalized likelihood ratio test is used to detect free spectral slots...
