Positioning in Indoor Mobile Systems [PDF]
, 2010 At present times people travel far greater distances on daily bases than our not so distanced ancestors had travelled in their lifetimes. Technological revolution had brought human race in an excited state and steered it towards globalization. Nevertheless, the process of globalization is not all about new and faster means of transportation or about ...

Fuzzy Logic Indoor Positioning System
International Journal of Interactive Multimedia and Artificial Intelligence, 2008 The GPS system is not valid for positioning indoors, thus positioning systems are designed using Wi-Fi technology that allows location of a device inside buildings. The use of fuzzy logic is argued by the failure to find positioning systems based on this
