Modeling and Detecting Feature Interactions among Integrated Services of Home Network Systems

This paper presents a framework or formalizing and detecting feature interactions (FIs) in the emerging smart home domain We first establish a model of home network system (HNS). where every networked appliance (or the FINS environment) is characterized as an object consisting of properties and methods Then. every HNS service is defined as a sequence of method its of the appliances Within the model. we next formalize two kinds of FIs (a) appliance interactions and (b) environment interactions An appliance interaction occurs when two method invocations conflict on the same appliance, whereas an environment interaction arises when two method invocations conflict indirectly via the environment Finally, we propose offline and online methods that detect FIs before service deployment and during execution respectively Through a case study with seven practical services, it is shown that the proposed framework Is generic enough to capture feature interactions in HNS integrated services We also discuss several FI resolution scheme, within the proposed framework.
