| Abstract | Currently, there are numerous location technologies that are used to determine the position of mobile devices in a space or grid, based on some mathematical models, where positioning means allowing a mobile device to be aware of its location with different degree of precision and accuracy. Unfortunately positioning systems have failed to grow in terms of usage by a common man because they haven't been ubiquitous. The local positioning systems fail to work outdoors where as the conventional GPS based positioning systems don't work inside buildings due to the absence of line of sight to satellites, while cellular Bluetooth, RFID, IR positioning methods generally fail to provide a satisfactory degree of accuracy. So there is a need for positioning systems that can work both indoors and outdoors, hence giving birth to the concept of Hybrid Positioning System (HyPos). In this study eight different HyPos are reviewed. The HyPos reviewed consist of technologies like RFID, CDMA, TV signal, Cell, Wi-Fi, and pseudolites. All these system are observed on the basis on availability, accuracy, and cost of development. From the reviewed system two systems are based on the integration of Wi-Fi and GPS which are reviewed in detail because after initial review it was found that the integration of Wi-Fi and GPS is best in terms in term of defined criteria. After the selection of technologies a framework is developed for the development of Wi-Fi based positioning system. An open source wardriving tool is developed, which is to be used in the first phase of the framework. Details of the tool are also given |
