Low-Power Network Support for the Recovery of Collapsed 6G Systems

Supervisor: Leon Würsching Frank Hessel

A resilient 6G network will be prepared for different failure scenarios and can absorb incidents to a certain level. However, there may be incidents that cannot be absorbed, e.g., a failure of the entire 6G core network due to a large-scale cyber attack. Further possible consequences of such an incident include a large-scale power outage affecting either parts or even the entire mobile network. In this type of scenario, the 6G network would collapse and split into smaller networks. Such a small network could, e.g., consist of a single isolated base station running on emergency power, and the users connected to it. From here, isolated basestations have to reconnect with other base stations to recover some functionality of the 6G network. However, the need to conserve energy further complicates the recovery process because base stations are running on emergency power. This thesis evaluates how such a recovery process of the 6G network can be supported with ad-hoc low-power networks. In this thesis, the student will explore how isolated base stations can coordinate the reconnection of isolated base stations via a low-power network. This includes discussing and choosing a suitable lower-layer protocol as a basis for the low-power network implementing a basic consensus protocol to make distributed decisions testing the developed protocol in simulation.

Long-Range Network Support for the Recovery of Collapsed 6G Systems

Supervisor: Leon Würsching

A resilient 6G network will be prepared for different failure scenarios and can absorb incidents to a certain level.

In this type of scenario, the 6G network would collapse and split into smaller networks. Such a small network could, e.g., consist of a single isolated base station and the users connected to it. From here, isolated basestations have to reconnect with other base stations to recover some functionality of the 6G network. This thesis evaluates how such a recovery process of the 6G network can be supported with ad-hoc long-range networks. In this thesis, the student will explore how isolated base stations can distribute relevant information via a long-range network. This includes discussing and choosing a suitable lower-layer protocol as a basis for the long-range network identifying relevant metadata that should be distributed to other base stations designing the basic long-range network protocol implementing the developed protocol and testing it on our testbed.
