Abstract-Collaborative Working Environments (CWEs) are getting prominence these days. With the increase in the use of collaboration tools and technologies, a lot of sharing and privacy issues have also emerged. Due to its dynamic nature, a CWE needs to adapt the changes into accordingly. In this paper, we have implemented the Adaptive Dynamic Sharing and Privacy-aware Role Based Access Control (Adaptive DySP-RBAC) model which provides user's information privacy to dynamically adapt the changes occurring in the system at any time. The proposed model has been implemented as a prototype and tested. Results have shown that our system efficiently and effectively adapts access rules according to the changes happening in a CWE along with preserving the user's information privacy in the system.

The model generalized for different architecture description languages and various architec tural styles.In [18] a method have been proposed for specifying and executing adaptive dynamically in which software systems combined model-driven and aspect-oriented techniques to help engineers to control complex ity of such systems, while offer providing a higher degree of automation and evaluation.In [19] a framework called RESAS has been proposed to implement real-time software systems; it allows real-time systems to be adapted with time constraints and hardware failures.

Abstract-Nowadays the role of software architecture is obvious. Both complex requirements and non-deterministic chang ing environments lead software architecture to face with problems for coverage of requirements and environments. Consequently, the configuration of the software architec ture is faced with challenges even in run-time. Being able to deal with such problems requires new techniques to be used. In spite of variety of related works performed in this domain, improvements are required in some aspects such as consideration of overlap and contradictory require ments and also effects in dynamic environments. In this paper, a dynamic model is presented for handling chang ing requirements which makes use of the configuration management concepts such as versioning, composition, consistency, construction, and selection; hence the possibility of configuring software architecture in overlapped and contradictory requirements and dynamic environ ments has been provided in the proposed model. The model includes change management and versioning activities for software architecture and its artefacts. The results of performing the proposed model on a case are reported in this paper.Index Terms-Dynamic model, software architecture, requirements handling, configuration management. I. INTRODUCTIONToday the need for interoperability of software systems is of importance more than ever ‫‬ . ‫‬ Therefore satisfaction of special requirements of this domain requires solutions that include identifying and handling quality attributes such as availability, flexibility, etc. One of the most important requirements is the run-time configuration management considered as the most prominent requirement of dynamic environments. Adaptable soft-ware architecture is able to be adjusted in variable environmental conditions [1].Changes can occur at different times, such as: design time, before implementation, or at run-time [2]. Various factors lead to changes in the software architecture, e.g. changing customer needs, need to create new software faster, adding new software features and modifying soft-ware faults during maintenance phase [3]- [5]. That order to fix these changes making use of configuration management and its concepts.The architecture has been integrated with the require ments in such a way that it is impossible to judge which of them Manuscript received November 10, 2014; revised January 7, 2015 came earlier than other [4]. Although there is a relationship between architecture and software requirements, but there are different opinions on the nature of this relationship [3]. In fact, requirements are description of problem but software architecture represents the struc ture of software system that solves the problem with its main elements such as components and connectors. In fact, because of the different nature of the two, there is a gap between them.Despite much work performed in identifying and meeting requirements in the area of configuration management of software architecture, there is still no perfect proven solution...

“…RELATED WORK Rule-based adaptation of application behavior: Application/service adaptation using rule-based techniques was systematically studied in Accord and applied to objects [6], components [25], [31] and Grid services [23] for scientific applications and workflows. RESAS [9] supports dynamic rule-based adaptation of real-time software and provides tools for programmers. Specifically, it provides algorithms to modify the reliability and/or timeliness of software without affecting other aspects of its functionality.…”

Abstract-The increasing heterogeneity, dynamism, and uncertainty of emerging DCE (Distributed Computing Environment) systems imply that an application must be able to detect and adapt to changes in its state, its requirements, and the state of the system to meet its desired QoS constraints. As system and application scales increase, ad hoc heuristic-based approaches to application adaptation and self-management quickly become insufficient. This paper builds on the Accord programming system for rule-based self-management, and extends it with model-based control and optimization strategies. This paper also presents the development of a self-managing data streaming service based on online control using Accord. This service is part of a Grid-based fusion simulation workflow consisting of long-running simulations, executing on remote supercomputing sites and generating several terabytes of data, which must then be streamed over a wide-area network for live analysis and visualization. The self-managing data streaming service minimize data streaming overheads on the simulations, adapt to dynamic network bandwidth, and prevent data loss. An evaluation of the service demonstrating its feasibility is presented.
