Hybrid metaheuristic

model

The network consistency was

improved by 8.7%

Lack of adaptability to

new threats

optimization and Nomadic

People Optimizer

29.8% reduction in delay

This approaches suffered

from lower security and

high resource utilization

Veeramakali et al.26

ODLSB

Attained sensitivity, specificity,

and accuracy were 92.75%,

91.42%, and 93.68%, respectively

It could not handle centralized

architectures and the lack

of security issues

Ramani et al.27

ODMSM-FL

Performance metrics like transaction

throughput of 102.75 Kbps, block

processing time of 42.28 ms

It had overall limitations in performance

and security regarding health

systems in the IoMT framework

Praveena Anjelin et al.28

CNN

It achieved 17% improvement

in accuracy and showed 35%

less complexity

Produce the false alarms that

lead to security attacks or

cyber-attacks

Ahmad et al.29

TLADE

Latency: 0.838s

Limited adaptability to

real-time encryption demands

Alsaeed et al.30

Group Authentication

Framework for IoMT

Latency: 0.5s,

Throughput: 400 TPS

High computational cost

due to blockchain overhead

Ramani et al.31

ODMSM-FL

Transaction throughput: 102.75 Kbps,

data retrieval delay: 64.02 ms,

accuracy: 86.32%

Federated learning complexity

may lead to higher energy

consumption in IoMT devices
