A trust evaluation scheme of service providers in mobile edge computing

Abstract

Mobile edge computing (MEC) is a new computing paradigm that brings cloud services to the network edge. Despite its great need in terms of computational services in daily life, service users may have several concerns while selecting a suitable service provider to fulfil their computational requirements. Such concerns are: with whom they are dealing with, where will their private data migrate to, service provider processing performance quality. Therefore, this paper presents a trust evaluation scheme that evaluates the processing performance of a service provider in the MEC environment. Processing performance of service providers is evaluated in terms of average processing success rate and processing throughput, thus allocating a service provider in a relevant trust status. Service provider processing incompliance and user termination ratio are also computed during provider’s interactions with users. This is in an attempt to help future service users to be acknowledged of service provider’s past interactions prior dealing with it. Thus, eliminating the probability of existing compromised service providers and raising the security and success of future interactions between service providers and users. Simulations results show service providers processing performance degree, processing incompliance and user termination ratio. A service provider is allocated to a trust status according to the evaluated processing performance trust degree.

“…Besides, an adaptive weighting method was formulated from the fluctuation of QoS metrics which dwindled the impact of subjective factors on the trust evaluations. In [19], Monir et al evaluated the SP compliance to SLAs in Mobile Edge Computing (MEC). To this end, they defined four thresholds which assigned a trust status to the SP via the processing performance during service provisioning.…”
