Engineering Metadata Placement over MQTT 5 for Multi-Robot Fleet Coordination

International Conference RADIOELEKTRONIKA 2026

MQTT-based robot fleets need metadata for routing, tracing, schema evolution, request-response correlation, and tenancy, yet inconsistent placement can defeat broker filtering or expose sensitive fields. This paper consolidates a standards-compliant placement rule: routing and authorization fields go in the topic; observability and processing hints use MQTT 5 properties; schema-bound or sensitive fields stay in a versioned payload. The contribution is an engineering guideline and reproducible evaluation, not a new protocol. We state the OASIS User Property encoding rule as a design-aid formula and check implementation conformance at packet level, including both MQTT Variable Byte Integer length fields. A Rust testbed compares zero and 16 User Properties over Mosquitto, EMQX, and HiveMQ for two payload sizes and QoS 0/1. A separate four-carrier baseline quantifies wire bytes, broker-side filtering, ACL enforcement, and latency; controlled broker-egress impairment probes adverse conditions without claiming a physical multi-host result. Direct permutation tests, effect sizes, and bootstrap intervals replace inference from overlapping confidence intervals. All 95,658 captured PUBLISH protocol data units matched the intended property count and both length ledgers. Three of 12 header strata and one of six carrier strata rejected after Holm correction, ruling out a universal latency-neutrality claim while supporting the placement rule through broker visibility and ACL results on the measured single-host Docker path.

High Performance Adaptive Learning & Testing System with Safe Dynamic Plugin System

2026 12th International Conference on Communication and Signal Processing (ICCSP) · Smart Education Systems

Modern software systems, particularly in domains like Computerized Adaptive Testing (CAT), demand a balance of high flexibility and robust reliability. This paper elaborates on the implementation of a new CAT system using the Rust programming language. Rust’s innovative ownership model guarantees memory safety without a garbage collector, while its powerful generic programming and meta programming capabilities enable a highly flexible and maintainable architecture. We demonstrate how these features allow us to encapsulate complex adaptive logic into reusable components, reducing both the system’s overall complexity and potential for bugs. The resulting platform aims to provide a stable foundation that is more adaptable than current systems, offering distinct advantages for personalized learning and assessment.

SafePulse: A Memory-Safe Rust Architecture for Deterministic Real-Time ECG Alerting with Optional LLM Enrichment

Suyu Jiang, Haozhe Ruan, Shihao Wang, Jiuyuan Zhao, Luo Chen, Aquil Mirza Mohammed

2026 International Conference on Artificial Intelligence for Health and Education (ICAIHE) · Track 1: Emerging AI Technologies for Health and Education

Processing an LLM call is simple and slow, but fast recovery alerts are essential for real-time ECG decision support. We introduce SafePulse, a system in which an uncut alarm priority contract is implemented: time constraints allow the LLM to interpret and accumulate asynchronously, but ECG alerts are transmitted synchronously via a dependent optical path. By separating each device into an individual SessionActor, the risk of shared security state at the application layer is reduced. On MIT-BIH records 100–109 the detector achieved Se = 98.6% and PPV = 98.7%. In an injected-fault matrix of 16 cells (4 fault profiles × 4 concurrency tiers, 1000 trials/cell), event-level deterministic streams showed tuple mismatch count 0, with Δalerts = 0 and Δp95/p99/p999 = 0.0 μs. This study integrates LLM enrichment in a safety-constrained monitoring pipeline and demonstrates its architecture and validation mode. Extension code, figures, and complete results are provided as Electronic Supplementary Material.
