SOA Adaptation using Fuzzy Theory in Context-Aware Mobile Computing Model

Service Based Applications (SBA) running in incongruous environments are subjects to varying constraints that can lead to fluctuations in the quality of the application, alternatively it is desirable to count on autonomic mechanisms to guide the adaptation of SBA according to changes in the computing infrastructure. Note that it is possible to have a set of different adaptation strategies applicable in the same situation. Context-aware mobile computing model is designed to automatically adapt its behavior to current contextual requirements and choose the best adaptation strategy according to the system requirements. This model provides all functionalities of MAPE-K model and uses Fuzzy theory in both analysis and plan phases to characterize adaptation necessity and choose best adaptation strategy in accordance with fundamental criteria.)
