Toward Fault-Tolerant Deadlock-Free Routing in HyperSurface-Embedded Controller Networks
HyperSurfaces (HSFs) consist of structurally reconfigurable metasurfaces whose electromagnetic properties can be changed via a software interface, using an embedded miniaturized network of controllers. With the HSF controllers, interconnected in an irregular, near-Manhattan geometry, we propose a robust, deterministic Fault-Tolerant (FT), deadlockand livelock-free routing protocol where faults are
