Energy Efficient Determinism in WSN through Reverse Packet Elimination
Kvist, Fredrik; Urke, Andreas Ramstad; Øvsthus, Knut (Peer reviewed; Journal article, 2020)Recently, the industrial wireless sensor network (WSN) has gained attention as a complement to wired networks due to its flexibility and lower installation cost. We present a novel Reverse Packet Elimination (RPE) algorithm ... -
Field trials of two 802.11 residual bandwidth estimation methods
Nielsen, Martin N.; Øvsthus, Knut; Landmark, lars (Chapter, 2006)Ad hoc networks have attracted much attention due to their decentralized architecture and potential mobility. The latter promise has sparked research aimed towards routing and quality of service (QoS) admission schemes. ... -
Implementation and deployment evaluation of the DMAMAC protocol for wireless sensor actuator networks
Kumar Somappa, Admar Ajith; Øvsthus, Knut; Kristensen, Lars Michael (Peer reviewed; Journal article, 2016)The increased application of wireless technologies including Wireless Sensor Actuator Networks (WSAN) in industry has given rise to a plethora of protocol designs. These designs target metrics ranging from energy efficiency ... -
Layered autonomous TSCH scheduler for minimal band occupancy with bounded latency
Urke, Andreas Ramstad; Kure, Øivind; Øvsthus, Knut (Peer reviewed; Journal article, 2020)Robustness and bounded latency are among the key requirements in wireless industrial networks. A typical traffic patterns is convergecast, where sensors sends data towards a sink, resulting in a funneling effect with ... -
Modelling the Optimal Link Length in Wireless Sensor Networks for Two Different Media Access Protocols
Øvsthus, Knut; Nilsen, Espen; Kampen, Anne-Lena; Kure, Øivind (Peer reviewed; Journal article, 2015) -
A Survey of 802.15.4 TSCH Schedulers for a Standardized Industrial Internet of Things
Urke, Andreas Ramstad; Kure, Øivind; Øvsthus, Knut (Peer reviewed; Journal article, 2021)Concepts such as Industry 4.0 and Cyber-Physical Systems may bring forward a new industrial revolution. These concepts require extensive connectivity far beyond what is provided by traditional industrial networks. The ... -
Utilising LiDAR for fall detection
Frøvik, Nikolai; Malekzai, Bashir Ahmad; Øvsthus, Knut (Journal article; Peer reviewed, 2021)Autonomous driving generates several low‐cost technologies, such as light detection and ranging (LiDAR). Due to this, the LiDAR technology has experienced impressive performance improvements. Our ambition is to capitalise ...
