Robot sensor network turns readings into machine-readable data
A model-based system for wireless sensor networks produced semantically enriched measurements, while most micro-ontology generation took place within 500 microseconds. Compression depended on the serialization format, and the reported engineering results came from an illustrative robot-based setup.

Lightweight AI keeps simulated drone network near optimum
A simulation case study reports that CTS kept a UAV-mounted RIS network above 90% of an optimal data-rate benchmark and delivered orders-of-magnitude gains in energy efficiency over some strategies. The authors say the approach could help under tight onboard energy and processing limits, but prototypes and field trials are still needed.
