SUMMARY:

Fault tolerance in IoT systems is challenging to overcome due to its complexity, dy-
namicity, and heterogeneity. IoT systems are typically designed and constructed in layers.

Every layer has its requirements and fault tolerance strategies. However, errors in one layer
can propagate and cause effects on others. Thus, it is impractical to consider a centralized
fault tolerance approach for an entire system. Consequently, it is vital to consider multiple
layers in order to enable collaboration and information exchange when addressing fault
tolerance. The purpose of this study is to propose a multi-layer fault tolerance approach,
granting interconnection among IoT system layers, allowing information exchange and
collaboration in order to attain the property of dependability. Therefore, it is defined an
event-driven framework called FaTEMa (Fault Tolerance Event Manager) that creates a

dedicated fault-related communication channel in order to propagate events across the le-
vels of the system. The implemented framework assist with error detection and continued

service. Additionally, it offers extension points to support heterogeneous communication

protocols and evolve new capabilities. The empirical evaluation results show that intro-
ducing FaTEMa provided improvements to the error detection and error resolution time,

consequently improving system availability. In addition, the use of Fatema provided a
reliability improvement and a reduction in the number of failures produced.
