Adaptation is defined as the process of changing to suit different conditions in the environment. In other words, adaptation is a change in the structure, function or behaviour of the system in order to meet the current context. A ubiquitous system refers to the manner in which computer systems adapt to changes in the physical and virtual environments of computing platforms and communication networks, whilst enabling better interaction between humans and computers. The development and implementation of adaptive systems is rooted in the study of evolution and adaptation in the natural environment; accordingly, new methods have been continuously developed to enable computational adaptation. Adaptive computing is thus generally focused on the rapidly growing areas of, and the increasing demands for, ubiquitous computing and autonomic computing. This study first describes the notion of adaptation, before explaining adaptive systems and discussing adaptation in ubiquitous computing. The adaptation process in adaptive systems that occur in runtime stages is then presented. Moreover, the classification of adaptation is discussed in terms of questions relating to who, why and what, as well as how the adaptation occurs. Finally, different adaptation approaches are demonstrated and compared in order to select the most suitable approach for ubiquitous systems.

SUMMARYSoftware product-line engineering is the successful reuse of technology when applied to component-based software development. The main concept and structure of this technology is developing reusable core assets by applying commonality and variability, and then developing new software reusing these core assets. Recently, the emergence of service-oriented environments, called SOA, has provided flexible reuse environments by reusing pre-developed component structure as service units; this is platform-independent and can integrate into heterogeneous environments. The core asset of an SOA is the service. Therefore, we can increase the reusability of an SOA by combining it with the concept of a productline. These days, there exists research that combines SOA and productlines, taking into account reusability. However, current research does not consider the interaction between the provider and consumer in SOA environments. Furthermore, this research tends to focus on more fragmentary aspects of product-line engineering, such as modeling and proposing variability in services. In this paper, we propose a mechanism named 2-Level SOA, including a supporting environment. This proposed mechanism deploys and manages the reusable service. In addition, by reusing and customizing this reusable service, we can develop and generate new services. Our proposed approach provides a structure to maximize the flexibility of SOA, develops services that consider systematic reuse, and constructs service-oriented applications by reusing this pre-developed reusable service. Therefore, our approach can increase both efficiency and productivity when developing service-oriented applications.

The main difference is that we discuss other variabilities and effect of variation from one layer to other.…”

Abstract-Service-oriented computing has gained attention from researchers and industry due to various benefits. Enterprises are supported by SOC-based solutions. Enterprise requirements change with the customer needs, market conditions, and variability is often needed in SOC. Research usually focuses at variability on the business process level and ignores variability at other layers. In this paper, we show what kind of variability can occur and how it spans across all layers of SOC. We present some example scenarios to discuss different kinds of variability and their reasons in SOC environments. Finally, we classify variability to show that variability is not an isolated problem in a single layer.
