Trust Evaluation of Service level Agreement for Service Providers in Mobile Edge Computing

Mobile edge computing (MEC) is regarded as the extension of cloud computing services to the network edge. However, due to the lack of experience between service users and service providers, users always doubt about the fulfilment and satisfaction of their needs. This paper proposes a trust evaluation scheme that evaluates the service provider compliance to the service level agreement, thus, indicating its trust status. On the other hand, dissatisfaction rates are being computed, to show the drawback aspect of each service provider. This helps future users to get acknowledged of service providers' past interactions prior dealing with them. Therefore, eliminating the probability of existing compromised service providers and raising the security of future interactions between service providers and users in the MEC environment. Simulation results show that the higher SLA compliance, the lower the value of the service dissatisfaction rate given.
