The importance of the road infrastructure for the society could be compared with importance of blood vessels for humans. To ensure road surface quality it should be monitored continuously and repaired as necessary. The optimal distribution of resources for road repairs is possible providing the availability of comprehensive and objective real time data(More)
Wireless sensor networks (WSNs) have been a widely researched field since the beginning of the 21st century. The field is already maturing, and TinyOS has established itself as the de facto standard WSN Operating System (OS). However, the WSN researcher community is still active in building more flexible, efficient and user-friendly WSN operating systems.(More)
Often software for wireless sensor networks (WSNs) is developed using a specific event based operating system (OS) such as TinyOS. However, this requires steep learning curve for the new developers. Other operating systems for embedded devices have limited support for new hardware platforms. Our goal is to provide an operating system for resource(More)
Monitoring wild animals, especially those that are becoming endangered (for example, lynxes and wolves) is important for biology researchers. Solutions for the monitoring already exist; however, they all have drawbacks, such as limited range or lifetime, sensing modality, reporting delays, unreliability of operation. In this work we describe our experiences(More)
Time to deployment for wireless sensor networks could be reduced by using commercial sensor nodes. However, this may lead to suboptimal flexibility, power consumption and cost of the system. Our pilot deployment for precision agriculture and fruit growing research showed similar conclusions and outlined the design decisions leading to SADmote: a new sensor(More)
Wireless sensor networks (WSN) consist of a number of lowpower spatially distributed autonomous nodes equipped with means of communication. Developing software for WSN is challenging; operating system (OS) support is required. In this paper we present MansOS, a portable and easy-to-use WSN operating system that has a smooth learning curve for users with C(More)
Intelligent driving is a promising area for increased safety and comfort. Vehicular communication is an essential part of building such intelligent systems. To provide inter-operability of wide vehicle range, common standards are needed. One of recently established standards for vehicular networks is IEEE 802.11p. However, 802.11p hardware platform market(More)
Maritime operations involve complex tasks that must be taught through practical training. Using modern technologies offshore simulators can serve as realistic environment for training. The degree of immersiveness can be increased by replacing conventional input devices (keyboards, joysticks) with natural user interface (NUI) devices. This paper surveys(More)
Safety is an important aspect of transportation systems for both, the drivers and pedestrians. Significant part of road accidents are related to driver inability to react in time on sudden hazardous situations, such as pedestrians or wild animals on the road, a car stopped in case of emergency, or a slippery pavement segment. In this paper we propose an(More)
