Neuromorphic Computing in Outer Space: Intel Loihi Deployed On-Satellite for Spike-Based Software-Defined Communication

Le résumé fourni par la source

In space exploration and communication technology, software-defined networking architectures significantly improve the communications throughput and latency. This study developed a cognitive agent based on Q-learning with continuous learning capabilities to select optimal routing options in a dynamically changing networking environment. This proposed method achieves up to 90% reduction in measured Internet Control Message Protocol (ICMP) round-trip time compared to the Dijkstra shortest-path baseline under identical test conditions. Under dynamically changing network link latency conditions, the cognitive agent achieved a 90% success rate in routing packets in laboratory experiments. The agent was executed on neuromorphic hardware called Intel Loihi. However, due to the system’s power limitations, a simplified version of the agent was engineered to launch into space aboard a CubeSat. The CubeSat was launched in January 2022, making a historic milestone as the first launch of a neuromorphic system into space. The developed applications were successfully executed in space.
