Complex structures
Fault tolerance
IoT networks
Networking topology

Many Internet of Things (IoT) - based networks are being built to develop
applications spanning multiple domains. Many small to large devices
connected in various ways increases the risk of IoT networks failing. Small
devices in the devices layer frequently fail due to their small size and high
usage. Intermittent failures of the IoT networks lead to catastrophes at times.
The IoT systems must be designed to be fault-tolerant. Fault tolerance of IoT
networks must be computable so that the same can be considered while
designing IoT networks. However, the computation of fault tolerance of IoT
networks is complex, especially when heterogeneous structures are used for
building a specific IoT network. Fault tree-based models are not suitable for
computing fault-tolerance of complex models, which requires probability
assessment. Hybrid fault tolerance computing models have been presented in
this paper that consider both linear and probabilistic methods of computing
the fault tolerance considering many complex networking topologies used in
each layer of IoT networks. The fault-tolerance computing models are
formal methods that can be used to compute the fault tolerance of any IoT
network built with any internal processing. The accuracy of fault tolerance
computing is 12.9% higher than other methods.
