dc.description.abstractSince its conception IEEE802.15.4 was designed for small, low power, low bandwidth applications that could be used by low footprint devices. Because of its features, it is currently used as the foundation of many internet of things (IoT) protocols. Among these protocols, Thread stands out. Thread is a wireless communication protocol that stands out from the rest of its predecessors, because it allows IPv6 connections natively, in this way, Thread devices have the ability to be part of the global IP network, with all the advantages that this means. A particular device, the Border Router, is a device that acts as a gateway, at the physical and link layer. In this way, Thread devices that use IEEE802.15.4 can communicate transparently at the network layer and higher layers. Currently, the Border Router has been implemented using an architecture that uses an Network Co-Processor (NCP). The authors estimate that this architecture has several disadvantages, therefore, a new and alternative architecture is designed, implemented and tested, which is contrasted with the architecture that uses the NCP. As a case study, a Structural Health Monitoring (SHM) application is presented, using the newly designed Border Router, in which the devices are temporarily synchronized and interact with a server using User Datagram Protocol (UDP) and Internet Protocol version 6 (IPv6) . This application was intended to be used for parameter estimation of structural models for SHM. The results show the Border Router is superior in latency with a small increase in the packet loss rate, however, with additional work, the non-NCP Border Router could easily be far superior. In the SHM application, synchronization is achieved in the range of s when measuring synchronization with the oscilloscope, however, in practice, temporary differences in acceleration signals around milliseconds (1ms to 10ms) were observed.
