Implementación de un algoritmo para la recuperación de fallos en una topología lineal utilizando el estándar IEEE 802.15.4

Abstract

The objective of this work is to develop an algorithm that allows the recovery of faults in a linear topology based on the IEEE 802.15.4 standard, it provides solutions to transmission problems such as link failures or nodes. For which it describes the characteristics, limitations, applications; of the IEEE 802.15.4 standard. Jointly, the aspects related to the RCB256RFR2 transceiver nodes used for the implementation of the network are studied, as well as how to manage the channel in non-slotted CSMA / CA and its modes of operation: promiscuous and normal mode; as well as the programming language C / C ++ in which the algorithm is developed. The operation of the network and the performance of the proposed algorithm are evaluated, when the wireless sensor network presents faults of nodes or dropped links. The sensor nodes are located at the appropriate distance to generate information and transmit throughout the network, intentionally turning off the nodes with different roles in the network, to check the recovery of communication in the network
