Avaliação de experimentos empíricos para a estimativa de posição com o método Min-Max e com a aquisição do RSSI em rede IEEE 802.11n

Abstract

Increased data transmission capacity, coupled with improved processing power, will enable greater automation of manual processes. The Internet of Things with embedded systems has brought a wide range of applications enabling communication between devices. Coupled with the advancement, the need to locate in space with high accuracy is critical for devices to monitor and interact with the real world. This work aims to perform empirical experiments to evaluate the behavior of the position estimation error through Min-Max method in a variety of scenarios. In this context, the proposal aims to establish a system of message exchange between embedded devices with the purpose of acquiring data to determine their distance, using the RSSI technique, and then perform the calculation of the estimated position. It was noticed the lowest error in the scenario with the greatest distance and the largest amount of anchor nodes, while in the scenario with the smallest distance, there were no influences of the amount of anchor nodes.
