Table 49 Consensus mechanism and latency impact.

From: A hybrid deep learning model for detection and mitigation of DDoS attacks in VANETs

Consensus mechanism

Avg latency

Fault tolerance

Use case justification

RAFT

10–60 s

High

Not suitable due to latency

PoW

 ~ 100–300 ms

Moderate (f ≤ (n-1)/3)

Best fit for VANET

PBFT

 ~ 150 ms

Crash fault-tolerant

Good for lightweight VANET chains
