System-Level Power-Accuracy Trade-Off in Bluetooth Low Energy Networks
Location awareness is a key service in mobile devices. For indoor localization, radio frequency (RF) based distance estimation methods are the most viable. An economically favorable method using RF is received signal strength indication (RSSI) as there is no additional hardware required in the mobile devices. Localization is performed relative to fixed landmark nodes. Bluetooth (BTH) is a widely available standard that can be employed for such purpose. This work explores the potential of BTH and Bluetooth Low Energy (BLE) protocols in terms of power consumption and position accuracy. At time of writing there are no known simulators with support for BLE. The major contribution of this work is the design of a simulation infrastructure that supports BLE.
