This document proposes a novel method called Basil's Numbering Scheme (BNS) to overcome denial-of-service (DoS) attacks in Wi-Fi networks. In a BNS, the source node checks if communicating nodes are authorized using an Intruder Check Table. For suspicious packets, BNS redirects them and asks the user to enter a custom initial sequence number rather than a random one. This makes it difficult for hackers to predict sequence numbers and launch MAC spoofing attacks. Simulations show that under DoS attack, BNS improves throughput to near 100% and reduces packet loss compared to no security method.
