DIAC: an Inter-app Conflicts Detector for Open IoT Systems
ACM TRANSACTIONS ON EMBEDDED COMPUTING SYSTEMS(2020)
摘要
This article tackles the problem of detecting and solving potential conflicts among independently developed apps that are to be installed into an open Internet-of-Things (IoT) environment. It provides a new set of definitions and categorizations of the conflicts to more precisely characterize the nature of the problem, and it proposes a representation named “IA Graphs” for formally representing IoT controls and inter-app interplays. Based on the definitions and representation, it then describes an efficient conflict detection algorithm. Combining conflict categories, seriousness indicator, and conflict frequency, an innovative solution policy for solving various detected conflicts is developed, which also takes into account user preference and interest by providing interactive process. It implements a compiler and runtime software system that integrates all the proposed techniques together into a comprehensive solution. Experiments on SmartThings apps validate its significantly better detection efficacy over prior methods and effectiveness of conflict solution with user preference.
