Desarrollo de un sistema para determinar la posición de nodos basándose en RSSI, en una red WSN

Abstract

The number of sensors that work together in Wireless Sensor Networks (WSN) is hundreds or thousands, for this reason it makes it difficult for the network administrator to have control over the positions of each of these elements. It is vital for any administrator to have immediate and precise access to the positions of the elements of the network in order to ensure the maximum network performance and thus avoid incurring both human and technological expenses. This is how this project presents an application to determine the position of nodes in a WSN network based on RSSI (Received Signal Strength Indicator). In this work, the COOJA software was chosen to simulate sensor nodes and triangulation was used as a method to estimate their location. Simulations performed under this scheme show that the average error is approximately 7 meters, which is adequate for the 100-meter range of the simulated nodes. In addition, this information is presented in graphic and text form in a Web environment.
