Performance property prediction supporting variability for adaptive mobile systems

A performance property prediction (PPP) method for component-based self-adaptive applications is presented. Such performance properties are required by an adaptation middleware for reasoning about adaptation activities. Our PPP method is based on the Structure and Performance (SP) framework, a conceptually simple, yet powerful performance modelling framework based on matrices. The main contribution of this paper are the integration of SP-based PPP into a comprehensive model- and variability-based adaptation framework for context-aware mobile applications. A meta model for the SP method is described. The framework is demonstrated using a practical example.
