To configure a device in OpenWrt to function simultaneously as an AP (Access Point) and STA (Client) for network bridging, the following steps must be completed. This configuration allows the device to connect to an upstream WiFi (STA mode) while providing wireless access to downstream devices (AP mode), enabling network extension or use when a … Read more
Abstract The openness of wireless signal transmission enables seamless data transfer in wireless communications, but it also increases the risks of attacks, eavesdropping, and interference. In recent years, due to the randomness of physical layer channels, there is potential for it to replace traditional cryptographic encryption schemes that rely on extensive computation, and related research … Read more
Implementing Graph Structures in C: Adjacency Matrix and Adjacency List Representations In computer science, a graph is an important data structure used to represent relationships between objects. A graph consists of vertices (or nodes) and edges. Depending on different requirements, we can use various methods to represent a graph. In this article, we will introduce … Read more
