Abstract:
Several approaches have been proposed for localization and navigation based on WLAN, ZigBee, RFID and UWB over a decade. However, these systems are either expensive or lack accuracy and not all technologies are available in smartphones. Here we describe a Scalable Indoor location based service (SBI) a cost-effective solution based on Bluetooth. Using an appropriate filtering algorithm, we explored the possibility of determining users location based on signal strength. We also constructed a scalable connectionless service by geographic routing and roaming schemes. The whole experimental design thus guarantees a cost effective better navigation system.
