“…Similar to integrating a rule engine with the workflow engine, context information can also be integrated without changing the structure of the workflow engine. Integrating context data with workflows is known as "context-aware workflows" and it has been addressed by some studies (Abbasi et al, 2010;Abbasi & Shaikh, 2009;Ardissono, Furnari, Goy, Petrone, & Segnan, 2007;Cho et al, 2010;Joohyun Han, Cho, Kim, & Choi, 2006;Hsu, Wu, & Wang, 2010). Most of these studies extend a workflow language with context information which increases the complexity and hinders standardization on workflow languages.…”

“…Recently workflows have been used in pervasive computing environments because they are appropriate technologies for simplifying and customizing user interaction with his environment (Ranganathan & McFaddin, 2004). However, workflow technology is useful for predictable and repetitive processes (Abbasi & Shaikh, 2009) which are not suitable for dynamic pervasive environments. For this reason, context-awareness and adaptability must be accommodated into the workflows.…”

In this thesis study, a framework offering people help and guidance for organizing their daily activities is proposed. This framework allows users to model their daily activities in the form of workflows. Due to the dynamic nature of pervasive environments, workflows are enabled to be adaptable at runtime according to context information collected in pervasive environments. A workflow engine is used for modeling and management of workflows and a separate rule engine with Complex Event Processing (CEP) capability is incorporated into the framework for both enhancing workflow adaptation and execution and for rule-based context reasoning. The adaptation model in the framework allows modeling activities in a hierarchical manner, from high level abstract activities to more detailed ones. Event-driven Architecture (EDA) is utilized for loosely coupled interaction between the workflow engine and the rule engine, allowing these engines, other context sources and userlevel applications to exchange data among each other. Since workflow engines are sufficiently complex, EDA allows incorporation of context information into the workflow models without modifying the workflow language. A higher automation level than the level supported by workflows is proposed by processing events in pervasive environments using CEP. A prototype implementation is developed and the framework is evaluated with some real life examples and experimental tests demonstrating its applicability.

“…SOA and workflows management are promising technologies to meet Ubiquitous Computing requirements since SOA allows the applications functionalities to be provided and consumed as a set of services, which can be invoked by consumers through service interfaces published by service providers. On the other hand, a workflow describes the order of a set of activities to be executed by several services in order to achieve a specific goal [4]. SOA and workflows were selected since they are useful in environments in which lots of services provided by several providers are available and some of these services have similar functionality.…”

The development of complex applications is one of the major current challenges of Ubiquitous Computing. Such applications are difficult to develop because they use services provided by different context-provision middleware, thus being necessary to know the models used for communication and representation of context information for each one. This paper presents the semantic composition and Web service selection mechanisms provided by OpenCOPI, a platform designed to integrate context-provision middleware. In OpenCOPI: (i) the applications are described in a high-level of abstraction by using semantic workflows; (ii) the semantic composition is responsible for composing concrete services from abstract descriptions of the applications, and; (iii) the selection is based on service quality metadata and user preferences. This paper also presents an evaluation of the semantic composition and the Web service selection mechanisms considering a ubiquitous application.

“…Moreover, it provides an environment that facilitates the development and execution of fault-tolerant applications that use such services by composing semantic Web services [4] in a semantic workflow [5] composed of a sequence of abstract activities that must be performed by concrete cloud services in order to achieve the application's business goal. In order to execute such semantic workflow, it is necessary to create at least one execution plan containing a set of concrete Web services that perform each one of the activities specified in the workflow.…”

Abstract. Cloud-based applications are built from services offered by distinct third-party cloud providers. Most cloud-related information (service properties such as price, availability, response time, etc.) can change at any time during application execution. Therefore, it is essential to support the adaptation of applications in such dynamic conditions in order to ensure that the cloud services currently provided to deployed applications adhere to the established requirements. In this paper we present an autonomous adaptation process for cloud-based applications by replacing a service by an alternative one that fulfills the application needs. We discuss the factors that trigger an adaptation in a Cloud Computing scenario and describe the adaptation process within Cloud Integrator, a service-oriented middleware platform for composing, executing, and managing services provided by different cloud platforms.
