Evaluation of trust methods for service selection in IoT

Abstract

Internet of things is combining virtual world and real world together. In order to perform particular service, there are many similar service providers, which make selection quiet difficult for the end users. Hence trust plays a vital role..Trust computational model helps in evaluating the Trust for the purpose of reliable service management. It helps in reducing Risk factor and uncertainty. Current research lacks in comprehensive study on trust management in IoT. This paper categorizes existing Trust computational models into five basic building steps. Each step is elaborated into certain important attributes and properties. Several trust computational model are studied and classified according to these properties and attributes. Further we also provided important parameter of each trust step. This paper also discussed the open research issues in this area.
