Table 1 Literature survey of IoT-based healthcare monitoring model.

Khan et al.¹⁹

SMSH

Wider-face dataset

MATLAB simulation

Better security with minimum execution time

Lack of adequate medical information

Manogaran et al.²⁰

GC-MFR

Cleveland heart disease database

JAVA

Better detection accuracy and minimum task completion time

Data threats with higher cost

Kaur et al.²⁶

Random forest (RF)

Public datasets

WEKA open-source tool

97.26% accuracy and minimum cost

Improper security

Wu et al.²¹

Deep learning

Real-time dataset

MATLAB

Minimum overfitting and enhanced accuracy

Vanishing gradient, higher computational complexity, and cost

Zhu et al.²⁷

Edge-fog computing framework

Gliomas datasets

Azure cloud

Smaller latencies with higher accuracy

Does not promote gradual analysis

Juyal et al.²⁸

AI-enabled cloud-based IoT

Skin image dataset

MATLAB

Improved accuracy and detection rate

Lots of security threats
