The design of an algorithm that operates at the link level to synchronize the nodes that are part of a multi-hop linear topology is presented. The objective is that the nodes can transmit and receive frames in the same time interval and avoid the use of protocols at the network level to have end-to-end connectivity. To verify the effectiveness of the algorithm, a prototype network with a linear topology using the IEEE 802.15.4 protocol was implemented. The algorithm is executed in each node of the network. Therefore, the time interval in which the nodes must be active was calculated so that all nodes that are part of the multi-hop linear topology can transmit the monitoring data to the border node in the same time interval. The tests were performed in several scenarios in which one or several nodes transmit their data and it was verified that the nodes are activated simultaneously to operate in active mode. Based on the results, the algorithm performance was validated and provides a tool for the creation of applications associated with linear infrastructure monitoring.
