Redes de sensores inalámbricos para IoT: algoritmo para la eliminación de tramas repetidas en ambientes con topología lineal que operan con el protocolo IEEE 802.15.4.

Abstract

IEEE 802.15.4 is a short-range, low-power wireless communication protocol designed to facilitate the communication between devices, such as sensors and actuators, within a network. However, the protocol along with the nodes and the sensors are limited and can be inefficient. The most effective way to avoid excessive consumption of resources is to build algorithms with the potential to adapt to different situations that consume energy, time, and processing of all nodes such as message redundancy. In this study, we present an algorithm capable of eliminating repeated frames in environments with linear topology. Moreover, the algorithm is able to capture and compare the messages sent by the sensors that operate with the IEEE 802.15.4 protocol. With this, we demonstrate that it is possible to implement the algorithm on the nodes ATZB-256RFR2-XPRO. This project is organized into three chapters . The first chapter focuses on the concepts, components and characteristics of the sensor network, the linear topology, the IEEE 802.15.4 protocol, and the ATZB-256RFR2-XPRO node. The second chapter provides details on the development of the algorithm and its coding in the nodes. In addition, it contains the steps required to develop the code within an external sensor so that the nodes have the capacity to generate simultaneous messages through the network with linear topology. In the third chapter the results of the algorithm are shown, making a comparison of the sequences of messages received and transmitted.
