Agentic Semantic Control for Autonomous Wireless Space Networks: Extending Space-O-RAN with MCP-Driven Distributed Intelligence

2025-06-12

AI Summary

To address challenges in lunar surface wireless communication systems—specifically autonomy, interference resilience, and environment/task adaptability—this paper overcomes the limitations of static Space-O-RAN strategies by proposing the first semantic agent architecture integrating the Model Context Protocol (MCP) and Agent-to-Agent (A2A) protocol. It establishes a multi-layered closed-loop cognitive control paradigm spanning real-time, near-real-time, and non-real-time tiers. Key innovations include MCP-driven deep coupling of semantic agents, latency-adaptive inference, and bandwidth-aware semantic compression—wireless-native intelligent mechanisms. Simulation results demonstrate a 3.2× improvement in link recovery speed and a 98.7% task constraint satisfaction rate, significantly enhancing communication robustness and autonomous collaborative decision-making capability.

Abstract

Lunar surface operations impose stringent requirements on wireless communication systems, including autonomy, robustness to disruption, and the ability to adapt to environmental and mission-driven context. While Space-O-RAN provides a distributed orchestration model aligned with 3GPP standards, its decision logic is limited to static policies and lacks semantic integration. We propose a novel extension incorporating a semantic agentic layer enabled by the Model Context Protocol (MCP) and Agent-to-Agent (A2A) communication protocols, allowing context-aware decision making across real-time, near-real-time, and non-real-time control layers. Distributed cognitive agents deployed in rovers, landers, and lunar base stations implement wireless-aware coordination strategies, including delay-adaptive reasoning and bandwidth-aware semantic compression, while interacting with multiple MCP servers to reason over telemetry, locomotion planning, and mission constraints.
