Techniques and Methodologies of Self-Adaptive Software and its Architecture: A Survey

Nowadays, due to the continuously changing en-vironment, modern software systems can work in a dynamic environment. But many changes occur at runtime so, to handle the changes self-adaptive mechanism plays an important role. To encounter the requirement of rapid application development adaptive software is used widely. Adaptive software architecture is based on three steps speculate, collaborate, learn. There are a lot of techniques for adaptive software architecture most appropriate technique is selected by comparing them. In this paper, we perform a survey on different research papers related to the self-adaptive system and self-adaptive architecture. After studied the techniques gaps in the literature are identified and compare those techniques. Different common parameters are identified and considered by studying literature. Then these parameters are used to analyze survey techniques which is helpful for researchers and future directions in this area.
