This paper presents a description of major principles of federated testbed for public safety communications activities, its concept, structure, objectives, and trial scenarios.
The implementation of pilotage task is inseparable from navigation information provided by shipborne navigation equipments. This paper presents a wearable pilotage system which adopts the PDA as the carrier for the electronic charts display as well as navigation information display and processing, through the Bluetooth wireless transmission to obtain the navigation information from shipborne AIS,...
AIS (automatic identification system), a new type of marine equipment, together with radar, are all the key navaid for a ship to navigate. Now in the seafaring, it is one of the most attentive research issues how to adequately and effectively use their information to improve the sail safety. The paper developed the integrated target information system based on ECDIS (electronic chart display and information...
We propose a pervasive usage of the sensor network infrastructure as a cyber-physical system for navigating internal users in locations of potential danger. Our proposed application differs from previous work in that they typically treat the sensor network as a media of data acquisition while in our navigation application, in-situ interactions between users and sensors become ubiquitous. In addition,...
Two difficult problems pertain to selection of an evacuation route according to each individual??s situation. One is constant supervision of the situation of a living space and detection of dangerous situa-tions; the other is detection of residents' respective positions. In this paper, we describe devices and systems for an indoor emergency evacuation using a mobile terminal such as a cell phone or...
One of the most important issue in maritime international transport is the necessity of increasing the level of safe in vesselpsilas navigation. We can achieve this goal using various methods. One of them is the enlargement and enrichment of navigational data processed by own deck computer net and external systems AIS (Automatic Identification System) and VTS (Vessel Traffic Service). The radar image...
The paper presents a new concept of the lossless radar images compression method for the needs of the navigation in marine traffic. A fundamental problem of vessel operation in marine transport is increasing safety level of own shipping and vessels cooperating. We can receive this aim using various ways. One of them is radar images compression method for the needs of the remote transmission. The radar...
Automatic identification system (AIS) is a system that enables ships to exchange information about ships and navigation, such as position, course, speed, name etc. automatically by VHF radio. The system is expected to contribute the improvement of marine traffic control and safety. In some congested waterways excessive transmission of AIS is a potential problem since the planning stage. In this study,...
