VESPER: Activity-Conditioned Smart-Home Network Testbed and VESPER-SH Dataset

VESPER is a reproducible, activity-conditioned smart-home network testbed. It couples embodied resident activity (a 3D simulator driven by LLM-generated daily schedules), stateful device-software simulations, live SmartThings and Matter/Home Assistant connectors, and a packet-observable IEEE 802.11 backend (mac80211_hwsim/wmediumd) on a single, timestamp-aligned event timeline. This lets resident actions, device state, automation decisions, and network frames be recorded and related within one experiment. This release accompanies a double-blind conference submission and is anonymized for review. Contents VESPER platform source and experiment configurations Persisted resident schedules and scene configurations (replayable without re-sampling an LLM) 802.11 packet captures (.pcap) and per-trial network measurements for the bridge vs. 802.11-aware backend comparison Proxy/broker and TAP-rule records for the activity-conditioned (Phantom-Delay) experiment VESPER-SH dataset: one-second windows, split files, baseline detector scripts, and a datasheet VESPER-SH dataset 17,983 one-second windows from 60 episodes across 20 simulated homes and 3 resident models Per-window activity, device, automation, and network features with controlled attack labels Home-disjoint and resident-disjoint train/test splits; baseline detectors and per-class results described in the datasheet Single access-point LAN Scope and limitations Device containers are stateful device-software simulations, not general vendor-firmware rehosting Network uses single-station/single-AP 802.11 emulation and is not RF/PHY-calibrated to physical hardware Attack labels are controlled, author-injected targets; the dataset is not established to generalize to physical homes or unseen attack implementations
