RSSI Strength Measurement in Wireless Sensor Network with and Without Obstacles

Abstract

AbstractIn today’s world, the influence of high-fidelity wireless sensor networks based on system on a chip (SoC) architecture has produced a robust framework of networking possibilities. These networks provide better latency and efficient power consumption in the WSN. This work presents a novel approach to analyze the effective variation in receiving signal strength indicator (RSSI) between two ESP8266 Wi-Fi microchips with or without the presence of obstacles. The proposed devices are configured to emit, scan and fetch the signal strength of one or more host networks at the same time. It can help to deploy the sensors in the network more effectively with respect to the distance. In this energy of nodes are getting optimized and communication link establishment between the neighbor nodes. This could assist in improving network switching capabilities by automatically analyzing the signal strength of the available networks from the most viable distance and connecting to them seamlessly in real time. This proposed architecture can be further enhanced by integrating with ESP-supported devices, which can be applied in exposure detection and contact tracing systems with the less power consumption in the WSN. This device can make the great change in the WSN deployment, so redundant nodes energy will be utilized properly with the help of RSSI values. So nodes can use the transmission energy with respect to the distance, which will make high energy optimization of the node, instead of using the same energy level of the short and long distance neighbor nodes.KeywordsIoTRSSISoCWi-FiArduino
