TROPOS BASED ADAPTATION FRAMEWORK FOR SELF ADAPTIVE SYSTEM

Today’s software complexity is increasing which in turn increase the need for software to work autonomously with least human intervention. Self-adaptive software work autonomously in unpredictable environment overcoming the failures and increasing the performance. Engineering selfadaptive software is very complex. In this paper generic adaptation framework using AOSE methodologyTropos has been proposed to develop Self-Adaptive System. In this Framework adaptation process is fully automated by making feedback loop as first class citizen. Two classes of requirements namely adaptive requirements to be monitored and evolution requirements to make changes on target system as a result of reconfiguration is used. Proposed framework is illustrated with case study Smart Travel Recommender System as it involves dynamic changes and is evaluated using existing system CARE framework and Tropos4As framework.
