  This work evaluates three Fog Computing dataplacement algorithms via
experiments carried out with theiFogSim simulator. The paper describes the
three algorithms(Cloud-only, Mapping, Edge-ward) in the context of an
Internetof Things scenario, which has been based on an e-Health systemwith
variations in applications and network topology. Resultsachieved show that edge
placement strategies are beneficial toassist cloud computing in lowering
latency and cloud energyexpenditure.
