This paper presents an application for positioning and tracking of a mobile node in a BluetoothBased wireless networks. The addressed experimental real time application is tracking a football player in a match. The places of a player are calculated using triangulation positioning techniques via a small Body-Tag attached to the player. Furthermore, using this new methodology of positioning, the ...

Inter-cell interference coordination in 3GPP Long Term Evolution system received much attention in recent years. However, most of the studies are based on ideal system with regular hexagon-shaped cell. The indoor environment has special characteristics that the building shape and BS locations are irregular; the traffic load has great variation compared to urban and rural area. So, conventional ...

background and aims: to obtain maximum advantages from orthodontic fixed appliances and to achieve the desired final occlusion, correct bracket positioning is highly necessary. in order to measure and determine bracket’s height, diverse gauges have been used. the objective of the present study is to determine and compare bracket positioning accuracy by using height bracket positioning gauge (hb...

The Ultra Wide Band (UWB) is a promising indoor positioning sensor. Its precise range measurement and wall penetration capability are well suited for indoor navigation. UWB anchor locations must also be carefully determined to achieve the optimal performance of a UWB positioning. However, previous approaches on the UWB anchor placement resulted in poor positioning accuracy around corners of an ...

Multi-constellation global navigation satellite systems (GNSSs) are expected to enhance the capability of precise point positioning (PPP) by improving the positioning accuracy and reducing the convergence time because more satellites will be available. This paper discusses the performance of multi-constellation kinematic PPP based on a multi-constellation kinematic PPP model, Kalman filter and ...

In this paper we present a micro-electrical mechanical system (MEMS) based pedestrian navigation system (PNS) for seamless positioning. The sub-algorithms for the PNS are developed and the positioning performance is enhanced using the modified receding horizon Kalman finite impulse response filter (MRHKF). The PNS consists of a biaxial accelerometer and a biaxial magnetic compass mounted on a s...

In the last decade, positioning has become a steadily growing research topic. The increase in use and availability of wireless networks has allowed for an ever growing exchange of information and increased communication capabilities. Mobile applications offer resource positioning, which can help in different areas of society. These applications can be used to track people with special needs or ...

The INET framework for the simulation tool OMNeT++ provides a TCP module, which can be used for evaluating various Internet applications. However, the implementation of this TCP module has not been state of the art. Some important features of modern TCP implementations – particularly Selective Acknowledgements (SACK) and a complete Flow Control – have been missing. In this paper, we first intro...

In order to provide the seamless navigation and positioning services for indoor environments, an indoor location based service (LBS) test bed is developed to integrate the indoor positioning system and the indoor three-dimensional (3D) geographic information system (GIS). A wireless sensor network (WSN) is used in the developed indoor positioning system. Considering the power consumption, in th...
