Authorization is a security mechanism that determines whether to allow users, devices, or applications to access specific resources, operations, or information based on their identity and permissions. In computer systems, networks, web applications, and other environments that require protection of sensitive data and resources, authorization is a key measure for ensuring security and implementing access … Read more
MQTT, as a lightweight publish/subscribe messaging protocol, provides real-time and reliable messaging services for resource-constrained IoT devices in low bandwidth, high latency, or unstable network environments. lwIP, as a similarly lightweight TCP/IP protocol implementation, minimizes the use of hardware resources, especially memory, while providing complete TCP/IP functionality, making lwIP very suitable for small embedded systems. … Read more
1. Introduction Recently, several requests have come in for audio and video calling solutions. Many people choose to use WebRTC, which is indeed a good option, but it has too many dependencies and a large amount of related component code, making development difficult. Therefore, we ultimately opted for our own solution, which involves streaming and … Read more
