Simulation dataset: Edge-enabled three-tier architecture for mobile commerce (iFogSim evaluation)

Per-request and windowed time-series metrics produced by an iFogSim-basedsimulation comparing two m-commerce deployment models over a single productcategory (KURTAS, 200-item catalog):1. **Cloud-only baseline** — every request served by centralized cloud infrastructure.2. **Edge-enabled model** — catalog, recommendation, cart, and billing pre-processing served at a fog/edge tier with a 100-entry LRU cache (60 s TTL).Protocol: 2000 warm-up requests (excluded, counters reset) followed by 500measured requests. Requests drawn uniformly over the catalog with fixed randomseed (42) for reproducibility.
