Network-Aware Service Pricing Approach for Fog Infrastructure as a Service

Fog Infrastructure as a Service (FIaaS) service model facilitates leasing of shared infrastructure resources such as compute, network, and storage resources on fog nodes deployed by Fog Service Providers. Leased resources are leveraged by Fog Tenants to deploy and manage application environments individually. Fog Tenants are charged by Fog Service Providers based on the amount of resources consumed and as per agreed SLAs. Fog computing paradigm differs from Cloud computing paradigm in several factors such as large-scale deployment, heterogeneity, very large number of nodes spread over vast areas, location-awareness, support for mobility and real-time interaction, etc. To cater the unique needs of fog environment, we have developed a novel network-aware approach for service pricing in FIaaS environments. We have shown by experiments using a simulated test environment that our proposed approach fairly charges the tenants based only on their applications' infrastructure resource consumption.
