The heterogeneity in hardware specification and the software specification of the end-device/user influences the overall QoS and QoE that tenant can provide. In order to achieve the best QoS and QoE, tenants need to choose fog nodes that are most compliant and most efficient for their end-devices. Specifically, end-device heterogeneity involves hardware specification in terms of the type of the device (e.g. smartphone, mobile sensor, drone, etc.), and computational power and network capabilities, which influence how the end-device/user interact with the tenant's fog applications deployed on the provider's fog server. Further, from the software specification aspect, the tenants need to consider what software they can install at the end-device/user-side and how well the client-side software may perform when it interacts with the fog nodes?
