Table 21 Blockchain parameter settings for VANET-DDoSNet++ deployment.
From: A hybrid deep learning model for detection and mitigation of DDoS attacks in VANETs
Parameter | Value / Setting | Description / Purpose |
|---|---|---|
Consensus protocol | Delegated Proof of Stake (DPoS) | Chosen for fast validation and energy efficiency |
Block size | 1 MB | Balances throughput and propagation delay |
Block interval | 2 s | Time between blocks to reduce latency |
Transaction size | ~ 250 bytes | Typical size of a VANET transaction |
Network bandwidth | 100 Mbps | Assumed VANET communication capacity |
Number of delegates | 21 | Number of elected nodes validating blocks |
Transaction throughput | ~ 2000 transactions/sec | Supports high volume from vehicular communication |
Transaction confirmation time | ≤ 4 s | Ensures quick consensus and confirmation |
Energy consumption per node | ~ 50 Joules per block | Optimized for vehicular edge devices |
Fault tolerance | Up to 33% malicious nodes | Security threshold of the consensus |
Cryptographic algorithms | ECDSA (Elliptic Curve Digital Signature Algorithm) | For authentication and integrity |
Smart contract support | Enabled | For automated trust management and alert broadcasting |
Block propagation protocol | Gossip Protocol | Efficient message dissemination in VANET |
Data storage model | Lightweight ledger pruning | Minimizes storage on edge devices |
