Energy Efficient Wireless Sensor Networks

Development of urban areas has created a need for stable, reliable and cost-efficient indoor GPS systems based on regularly available technologies. Such systems already exist and are in use. This paper proposes such a system with an emphasis on ease of use, long-term reliability or maintenance free through network redundancy techniques as well as an open-source architecture. The proposed architecture uses a Bluetooth/Wi-Fi’s RSSI (Received Signal Strength Indicator) parameter as relative to multiple mobile and fixed nodes to determine the distance to an object. The nodes, both mobile and fixed, are purpose-built for the object of this study and feature multiple other peripherals, as described in the paper. The basic implemented model of these nodes is also described in the paper.
