Describing and verifying integrated services of home network systems

This paper presents a framework to specify and verify integrated services of a home network system (HNS). We first develop a modeling language to describe the HNS and the integrated services. Complementing our previous work, the language captures each appliance as an object consisting of properties and methods, encapsulating the underlying protocols and platforms. We then present a method that verifies the integrated services with symbolic model checking, by translating the proposed language into the SMV (symbolic model verifier) language. Thus, it is possible to validate if the integrated service is specified as intended, automatically and exhaustively. Using the proposed framework, service developers can effectively detect design flaws in a single integrated service, as well as feature interactions among multiple services, in early stages of service development.
