[Retracted] SWOT: A Hybrid Hardware-Based Approach for Robust Fault-Tolerant Framework in a Smart Day Care

Table 3

SWOT analysis of algorithm SWOT.

Strength	Weaknesses	Opportunities	Threats
(i) All the devices in day care are monitored in real time and via one common module	(i) Device calibration is not anticipated	(i) SWOT can be easily integrated into other smart space environments as it has a generalized implementation approach	(i) The whole system is dependent on the ADC microcontroller, if that goes faulty, the system cannot perform at all
(ii) Easy to manage heterogeneous devices	(ii) it assumes that the ground device values are not biased	(ii) It can be tailored to accommodate any device or sensor
(iii) Efficient and economical solution for controlling appliances automatically	(iii) Hung devices or constant are not handled. Readings with a consistent value across time, even if they are within a normal range, are known as constant values
(iv) A new data log is maintained each day. So, not much storage is needed	(iv) Uncertainty faults that are induced by sudden events or situations or sporadic like fire, floods, chemicals, etc. cannot be tracked
(v) Low false alarm rate
(vi) High positivity rate
(vii) High precision
(viii) Very less execution run-time
(ix) Can track outliers, stuck at zero, missing data, drift, noise/Spikes
