In this paper, we focus on evaluating the performance of NTrip/RTK solutions for accurate and precise car navigation (analysis of both the accuracy and availability of RTK data using mobile communication). Our approach is to develop a functional system of determining lane positions on highways. A system is based on wireless radio communication among surrounding vehicles what complement and enhance the current vehicle driving system needs (lane change collision avoidance systems, vehicle tracking, lane keeping and obstacle avoidance).

Wireless Sensor Networks (WSNs) consist of densely deployed, independent, and collaborating low cost sensor nodes. The nodes are highly resource-constrained in terms of energy, processing, and data storage capacity. Thus, the protocols used in WSNs must be highly energy-efficient. WSN communication protocols achieving the lowest power consumption minimize radio usage by accurately synchronizing transmissions and receptions with their neighbors. In this paper, we show how network signaling frames of state-of-the-art synchronized communication protocols for low-power WSNs supporting mobile nodes can be used for positioning. We derive mathematical models for node power consumption analysis. The models provide a tool for estimating what kind of network lifetimes can be expected when average positioned node speed, the amount of anchor nodes required by the location estimation algorithm, and the location refresh rate required by the application are known. The presented analysis results are based on two kinds of node hardware: real node hardware prototypes having no Received Signal Strength Indicator (RSSI) support and typical values of an integrated chip using an IEEE 802.15.4 compliant radio with RSSI.

This paper describes a proposed methodology how a GIS-based security middleware solution can be enhanced by rule-based behavior analyses of the complex dynamic processes which are associated with emergency response. The results of the field tests of indoor positioning, when a wireless mobile node was moving around a testing environment in time, are presented here. The behavior of mobile node was monitored by means of Ekahau Wi-Fi real-time location system, and a RSSI map produced.

In this paper, questions related to design of WLAN radio map for fingerprinting based positioning were investigated. The experiment results show that with histogram based algorithms, the positioning accuracy improves as the number of histogram bins increases until the number of bins reaches eight. With the number of bins lower than this, the uneven bin distribution with separate bin for missing samples gives better accuracy than even bin widths. If the calibration data contains samples from several measurement directions, it is beneficial to combine them into one fingerprint, as this decreases the size of the radio map and gives at least the same accuracy as having separate fingerprints for different measurement directions. In the experiments, the combination of the signals from correlating sources before the computation of the radio map and position estimate decreases the positioning accuracy only by 1–2 m, but decreases significantly the size of the radio map. The best method for signal combinations depends on the bin configuration and position estimation algorithm.

This paper presents a hybrid localization algorithm for a Peer-to-Peer (P2P)-Positioning scenario, where “peers” are devices equipped with both a GNSS (Global Navigation Satellite System) receiver and a wireless communications interface. Through their GNSS receiver, peers obtain pseudorange estimates from satellites while they use their wireless interface both to communicate with each other and to obtain terrestrial range estimates. The proposed algorithm is an extended version of the distributed-weighted multidimensional scaling (dwMDS) [1] algorithm to be compatible with the hybrid P2P scenario where unknown peers infer their own positions by fusing both GNSS pseudorange and terrestrial range estimates. Simulation results show that the proposed hybrid dwMDS (hdwMDS) algorithm out-performs the cooperative version of the least squares algorithm. Moreover, they show the related benefits in term of positioning performance in a cooperative scenario in comparison to a non cooperative one based on GNSS-only positioning.

In the idea of the Sensor Web, sensors should be discoverable, accessible and taskable over the internet. In this paper, we present a mobile data collection framework for connecting wireless sensors with the Sensor Web by using mobile devices. The proposed system is an extension to Locawe platform including now mapping and WSN features together with features of SWE especially Sensor Observation Service (SOS) specified by the Open Geospatial Consortium. Therefore, the Locawe platform running on mobile devices is used to connect to 6LoWPAN sensors, store the measurements of the sensors on the device's memory, convert it into sensor web protocols and insert the measurements into a sensor service as soon as wireless internet connection is available. As a proof of concept, the system is used within an air quality monitoring scenario.

In the paper we discuss how data matrices are being applied in an experimental way in the MenoMaps research project. One of the outcomes of the project is a map-based service prototype with multipublishing channels capable of delivering the same map data for the users via different media. We demonstrate how the data matrices could be displayed on paper maps as a link to location-specific information. The most promising applications are those where the content is very dynamic. We also show how a map application on a multitouch wall display can be linked through a data matrix to a map application on a mobile phone, to support the user's smooth switch from one channel to another. We carried out a user study on experimental hiking maps among the visitors of a national park in Finland. The survey reveled that user-awareness of the 2D barcode technology and usage is still low.

A personal location context mashup solution called LBS 2.0 is introduced in this paper. A widget based on the LBS 2.0 idea is implemented on a mobile phone to aggregate multiple contents from the internet. A Symbian-based web runtime location service is applied for calculating the location information including position, distance, time, and speed. A geolocation service offers an interpretation capability between coordinates and addresses. The principles for indentifying mashup sources are described. Contents retrieving and parsing processes are explained. Finally, a personal location aware utilization scenario is presented to show the contexts combined in the LBS 2.0 mashup on a Nokia 5800 XpressMusic handset.

Precision positioning for moving targets is the key issue in urban rail traffic safety assurance and operational energy saving. Precision vehicle positioning can improve transportation capacity. Meanwhile, personnel tracking can enhance daily operations as well as rescue capabilities in the event an accident or emergency. This paper discusses the development of precision positioning solution based on UWB, Multi-sensors and Wi-Fi Mesh Network. Difference from the existing rail positioning technologies, the proposed approach is specially designed for underground tunnels, culverts and architectural indoor environments. The paper will also introduce a Time synchronization method which integrates the time base of COMPASS (Beidou) with IEEE 1588 technology, so as to avoid sole dependence on GPS clock signal. An innovation integration solution which will eventually reduce the investment of targets tracking system of urban rail and the personnel precision positioning technique will be the first-of-the-kind in Urban Rail Safety and Security applications.
