This project aims at providing a feasibility study about anti-jamming techniques for newly emerged MIMO p-LEO satellite (or LEO satellite swarm) systems. LEO satellites located 1,200 km above the Earth????????s surface provide ultra-wide coverage and light-of-sight (LOS) communications to ground terminals. By equipping multiple antennas on satellites and ground terminals, MIMO LEO satellites can exploit MIMO technologies with the LOS channels to enable more robust air-to-ground communications with higher throughput. This research will introduce an in-depth investigation and propose novel algorithms to realize the potential of anti-jammed MIMO p-LEO satellites.

This project aims to investigate and demonstrate the loss of a satellite node of multiple satellites (cluster or swarm) networking, such as MIMO or others, with reloading ground users??? traffic on a prioritized basis under the evolving threats. The new spatial dimension of satellite swarms unprecedentedly takes the system???s resilience and self-healing capability to the next level.

Proliferated low earth orbit (p-LEO) satellite constellations have emerged as enabling technologies for 6G networks due to their potential in global coverage and ubiquitous services, especially for rural and remote areas. The need for access equality via p-LEO satellites?????????????????? high communications capacity with ultra-wide ranges is more urgent than ever, as we have abruptly switched to remote living in the past year due to the pandemic. However, no convergent solution currently exists for p-LEO-based satellite networking infrastructures that leverage the synergy of space and terrestrial systems. Fundamental architectural, management and operational changes are still urgently required to realize such ground-space ecosystems. This project presents a serverless software-defined architecture that dynamically orchestrates communications and computation resources for a diverse set of 6G service-level agreements. This project provides a multi-tier machine learning framework that uses a unified control platform to optimize networking and resource configurations according to space and ground tiers?????????????????? peculiarities and interactions. The intelligence within collaborative learners (i.e., ground stations and satellites with computing capabilities) can realize efficient broadband access for multiple ground users. The proposed architecture can further establish high-throughput, reliable end-to-end transmissions through software-defined internetworking for global connectivity. The innovative use cases and ecosystem enhancement, including Ka-band adoptions, automatic network slicing, application-defined interfaces, are also investigated to boost end-to-end performance and significantly impact future human society.

Our overall project objective is to achieve cross-constellation broadband access and SLA assurance for transient on-demand user traffic. This project???s rationale is that once SDN-based infrastructures and enabling tools can be implemented, they can provide elastic network resources to multi-tenants by orchestrating multi-band, multi-orbit (e.g., LEOs, MEOs, GEOs) satellite networks.

This project aims at addressing the technical issues in the Space-Based Adaptive Communications Node (Space-BACN) by providing reliable connections between satellites in different constellations managed by diverse operators, including the government and the commercials, using optical inter-constellation links. Space-BACN should offer a coordination protocol and APIs to serve satellites in different constellations using a hierarchical architecture to enable cross-constellation connectivity.

This project aims to develop AI-native federated slicing and orchestration that enables the synergy of federated AI and network slicing for mega-constellation management and AI/real-time services. A federated edge learning setting facilitates multi-tier, multi-domain AI executions by jointly optimizing resource and networking configurations of ground and space tiers and multiple constellations. Hence, the proposed designs will create high-throughput, reliable end-to-end transmissions for global connectivity.

This project will employ in-network computation at 5G wireless edges and enable data processing to occur in the middle of the transmissions between multi-agents and remote cloud servers. Thus, it forges effective convergence of communication, computing, and learning with regard to wireless link bandwidths, available computing power, and collected data's statistical features. Also, this project will provide a privacy-preserving framework from decentralized data by exploiting in-network processing operations. The proposed framework can achieve sophisticated and heavy-loaded machine learning algorithms through multiple low-end control units. It, in turn, preserves the data privacy for massive mobile user information in ICT or sensing information and intelligent manufacture/control commands in industrial scenarios. On the other hand, the proposed solution can also offload computation to the networking infrastructure, releasing the burden of multi-agents.

The steep traffic growth on the Internet (+20-30%/year) continues and is accelerated due to the COVID-19 pandemic. The widespread teleconferencing and working at remote sites further boost traffic globally by 50% in a year. To fully take advantage of the 5G and future 6G mobile communication infrastructure and the considerable computation and storage resources in data centers, we have to bridge these in an end-to-end manner with minimized latency and broad bandwidth. This project will develop future programmable and resilient converged wireless-optical networks for next-generation wireless applications and mission-critical services.
