Many applications in wireless sensor networks require sensor nodes to obtain their absolute geographical positions. There are various localization algorithms have been recently proposed. Localization – finding the position of individual sensor nodes-remains one of the most difficult research challenges. Many applications based on networked sensors require location awareness; a node must be able...

Devices for Wireless Sensor Networks (WSN) are limited by power and thus routing protocols should be designed with this constrain in mind. WSNs are used in three dimensions (3D) scenarios such as surface of sea or lands with different level of highs. This paper presents and evaluates Three Dimensions Position Based Adaptive Real-Time Routing Protocol (3DPBARP) as a novel, real-time, position ba...

Virtual organizations in their different forms are becoming more and more common. In this position paper we present the case of a virtual organization consisting of 200 Germany-wide distributed freelancers. The fact that the virtual organization does not have a geographical center, that the work and the local structures of parts of the organization are very heterogeneous and that the freelancer...

Next generation networks consider context information to deliver personalized services, where this context can include positioning information. On the other side, positioning information is relevant to some of the network main functions: geographical routing, network coverage, enhanced security, power saving etc. Therefore determining the position of nodes in wireless networks is pivotal and th...

A solar cell is a type of renewable energy engineering technology that can convert photons coming from the sun to be converted into electrical energy. The amount by determined effective insolation time. Peak hours (PSH) are focus this research. This PSH analysis aims determine potential for obtained in geographical locations throughout year. Geographical location and position astronomical coord...

The growing diffusion of pervasive collaboration environments and technical advancement of sensing technologies have fostered the development of a new wave of online services whose functionalities are based on users’ physical position. Thanks to the widespread diffusion of mobile devices (e.g. cell phones), many services can be greatly enriched with data reporting where people are, how they are...

We present a Sequential Monte Carlo (SMC) based approach for performing Acoustic Geo-Sensing, i.e., the derivation of geoinformation from audio data, in context of the Graz Cell-phone Cycle Corpus (GC). In particular, we deal with the process of determining the geographical position of a mobile device in motion, based solely on the acoustic data recorded by its built-in microphone. Our approach...

The position of a mobile phone can be located using information from the radio network it uses. This paper presents two applications that make use of Wireless Application Protocol (WAP) and mobile positioning technology to provide location-based information to the user in real time. The applications use the user’s position to generate dynamic information. Besides, both applications also have a ...

The purpose of this article is to offer a development ofthe demographic map as an alternative to the geographical base-map for the presentation of areal data in epidemiology. The results of geographical investigations into disease morbidity or mortality are often presented cartographically and invariably the base-nap used is the normal geographical one, showing the relevant administrative areas...

Dealing with prepositions such as “near”, “between”, and “in front of” is very important in Geographic Information Systems (GISs). In most systems, real world distances are used to handle these prepositions. One of the difficulties in processing these prepositions lies in the fact that their geographical range are distorted in people’s cognitive maps. For example, size of an area referred by pr...
