Field Validation of Multi-Vendor IoT Sensing Platforms An Empirical Approach to Resilient Industrial Odor Mitigation

It establishes that abatement reduces emission and that reduced emission shrinks the dispersion range; that metal-oxide arrays can operate continuously for more than a year and that a field electronic nose can be stable under variable atmospheric conditions; and that vendor heterogeneity is a documented structural obstacle, with more than 300 IoT platforms forming closed ecosystems and proprietary formats rendering cross-vendor comparison impossible.

It does not establish multi-vendor co-deployment under field conditions, mitigation outcomes measured at the receptor, or behaviour under vendor failure. We propose a four-domain validation framework, specify platform-neutrality requirements, and state four falsifiable propositions.</i></p>
