This paper proposes a GraphRAG framework that combines knowledge graphs with RAG to enhance networking applications. It reviews existing RAG applications in networking, identifies their limitations, and presents a domain-adapted GraphRAG framework for wireless network optimization.

A case study demonstrates the effectiveness of GraphRAG in channel gain prediction.

Abstract

This paper proposes a GraphRAG framework that combines knowledge graphs with RAG to enhance networking applications. It reviews existing RAG applications in networking, identifies their limitations, and presents a domain-adapted GraphRAG framework for wireless network optimization. A case study demonstrates the effectiveness of GraphRAG in channel gain prediction.
