Improving Multi-Channel Wireless Network Security Performance Using Trust-Enhanced Blockchain Deployment

Wireless networks are constantly under security threats due to a large number of inherent vulnerabilities. Most of these vulnerabilities are due to improper deployment architectures, wherein rules for packet access, node access and router access are not strictly defined. These primary vulnerabilities expose the network to other secondary attacks, which further degrade network performance. These secondary attacks include but are not limited to, malicious packet injection due to improper trust levels, checksum invalidation due to packet tampering. In order to reduce the probability of these attacks, this text proposes a novel trust-based blockchain powered multi-channel protocol. This protocol utilizes a distributed blockchain based on proof of work (PoW) consensus for safeguarding the network against security threats. It is observed that the proposed protocol improves security performance by 8% when compared to other state-of-the art methods, and improves the QoS performance by 6% when compared to other blockchain & trust-establishment methods.
