SLA-based service provisioning approach in vehicular cloud network

Vehicular cloud network (VCN) enables the vehicles to act as servers in the cloud environment, considering the abundance of computing and storage resources. Service provisioning may be challenging due to the characteristic of VCN such as service pricing, resource variability, and resource mobility. In this regard, the most important challenges of service provisioning are quality of service (QoS), service availability, and fair/constant pricing. Previous research approaches to service provisioning in VCN involve one or two of the challenges above and none of these approaches are comprehensive. In this paper, we proposed a comprehensive approach to service provisioning in VCN, considering all the challenges above. The proposed approach consists of algorithms to improve the quality of service, service availability, and fair/constant pricing. The outcome of the research is an efficient service provisioning approach and a service level agreement (SLA) in the VCN environment. The proposed approach is evaluated by simulation. The results of simulating various scenarios indicate improvements in quality of service and service availability indicators. It also shows that a fair pricing mechanism has been used.
