Implementing integrated services of networked home appliances using service oriented architecture

Abstract

This paper presents a method to implement integrated services of networked home electric appliances, which provide more convenient and comfortable living for home users. The conventional methods generally employ a home server to achieve the integrated services. The server controls all the networked appliances in a centralized manner. However, as the number of sophisticated appliances increases, the centralized server suffers from the concentration of load, as well as a decline in the reliability and interoperability. To cope with this problem, we adopt the service-oriented architecture (SOA) for the implementation of the integrated services. In the proposed framework, the appliances export own features as services, and autonomously execute the exported services one another. Thus, the appliances are loosely coupled via the exported services without any centralized home server, which enables more flexible, balanced and reliable integrated services. We first present a framework to design and implement the integrated services based on SOA, and then illustrate a prototype system developed with Web services. We also define three kinds of metrics (i.e., reliability, workload, and coupling), and conduct a comparative evaluation between the proposed and the previous systems.

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

“…The digest version of this article was published as a conference paper in ICFI'05 [9]. Changes were made to this version, most significantly the revision of definitions of HNS and integrated services (Sect.…”

“…Taking our original definitions [9] (i.e., the appliance and environment interactions) into account, this method represents the conditions of FIs in LTL formulas, and verifies the formulas against HNS services described in PROMELA. Unlike ours, this method allows branches and loops in the service description, and can give complete proof within the model.…”

Validating Safety for the Integrated Services of the Home Network System Using JML

“…When multiple services are executed, we need to consider functional conflicts among the services. This is called the feature interaction problem 9) . We leave these limitations for our future work.…”

A Dynamic-SOA Home Control Gateway

“…One of the main research fields is today the construction of the in-house pervasive environment where intelligent electronic devices have to be deployed in order to provide the user with the desired software functionalities [13] [15]. An important issue concerns equipments themselves and their integration in the house's environment.…”
