The Implementation of IPM——a Kind of Programming Model of Context-Aware Application

The paper proposes a context-oriented programming model which is named Isotope Programming Model (IPM). The paper also discusses the implementation of IPM. IPM extends the object-oriented programming model and introduces new language elements, which simplifies the development of context-aware application and makes programmer only care about the logic of programming and free from the change of context data. The paper also eompares the IPM with object-oriented programming model and embodies the advantages of IPM in the fields of the development of context-aware application.
