This paper shows an initial approach of a system architecture for a wireless sensor network (WSN), addressing the maritime domain. Novel architectures, technologies and prototypes for WSNs have been in focus of researchers and economists for several years. The proposed system architecture is focused on maritime automation - the construction and maintenance(More)
This paper presents a hybrid MAC layer design for UWB based sensor networks to handle multiple access with the ability to combine localization and data communication. UWB networks allow high precision ranging and robust data communication in harsh environmental conditions and for this are well suited for typical automation applications. To minimize(More)
In this paper, a concept of a system for wireless locating and data communication for industrial applications is proposed. The proposed system employs ultra-wide band radio for decentralized spatial localization of mobile sensor nodes and for communication. Due to the robustness UWB radio transmissions, it can be used in shop floor environments, e. g. for(More)
—In this paper, a novel network protocol (MOIN-Mobile Open Infrastructure Network Protocol) for non synchronized UWB based wireless sensor networks is presented. Applications of classical protocols for such non synchronized networks, where anchor nodes are not synchronized for ranging and communication purposes, typically are not effective for simultaneous(More)
Lateration based real time locating systems (RTLS) require anchor nodes with known positions to calculate the position of a mobile target. The geometry of the anchor nodes constrains the accuracy of the locating. In complex environments such as ships or factory floors, obstacles in the line of sight between target and anchors decrease the precision(More)
