Fault Tolerance Method for Industrial IoT Edge Computing Based on Sparse Graph Attention

To address the issue of node overload and even failure due to resource constraints in the Industrial Internet of Things (IIoT) edge computing environment, the author proposes a fault tolerance method based on edge intelligence called SGAT-GAN (Sparse Graph Attention-based Generative Adversarial Network). This method integrates a fault prediction mechanism and utilizes Fault Embedding Encoder … Read more

Essential Insights for Embedded Engineers: Protocol Design is More Than Just Connectivity

by

As embedded engineers, we deal with “protocols” almost every day. From reading sensor data to coordinating multiple devices, any communication between devices relies on protocols. Many people think that protocol design is simple, merely involving the creation of a message format. However, in real projects, even simple scenarios often lead to issues like “devices cannot … Read more

Chapter 6: Multi-Agent Systems

1. Why Do We Need Multiple Agents? Division of Labor, Fault Tolerance, and Coverage of Specialized Fields A single agent can accomplish a “task,” but when faced with complex projects, multi-role collaboration, and high fault tolerance requirements, it becomes inadequate. Multi-Agent Systems (MAS) provide core value by enabling multiple specialized agents to collaborate, working in … Read more

Low-Overhead FPGA Multi-Bit Upset Mitigation Technology

Commercial off-the-shelf FPGAs are considered the only way to meet the increasing processing power demands of space applications. Due to their sensitivity to multi-bit flips, specialized design hardening techniques are required to address single particle effects in space applications. A fault-tolerant technology framework based on three levels: user logic layer, configuration memory layer, and control … Read more
