RSSI Based Device Monitoring with IEEE 802.15 in Wireless Sensor Network

Monitoring signal strength is a major concern in Wireless sensor networks (WSN). This paper discusses the latest product of Espressif system, ESP32 which is designed for embedded system and real time implementation. Range-based localization approaches use RSSI, or Received Signal Strength Indicator, to estimate the signal power of the receiver node. BLE devices uses low energy Bluetooth propinquity sensing to transmit a specific identifier. Where we can scan the BLE Devices between a particular range. The ESP32 is a very low-cost device that uses low power consumption where we can save energy. The ESP32 comes with a chip series of micro-controllers with Bluetooth capabilities and a dual-core microprocessor. In our proposed work we are working On finding the BLE devices from a particular RSSI data between a range. After each iteration of data collection, we are storing the data into Google sheets. The whole RSSI data is saved for further study or data analysis and a live data feed is displayed.
