Cloud computing has rapidly developed with emergence of various user mobile devices. Furthermore, Cloud Service Broker (CSB) is emerged, as service mediation is willing to provide profit of a cloud customer as well as a cloud service provider in cloud environment. As a result, cloud computing nowadays has the architecture, which can provide extended services by collaboration among service providers...
3rd party content service expands the variety of contents that IPTV usually distributes and opens the opportunity to create new and attractive content to anyone. However, the hosting service for 3rd party content demands high cost. Therefore, IPTV provider needs an effective strategy of resource management to minimize the cost. Thereby, the cost function is based on the IPTV management of content...
In this paper, we propose a promising multi-objective (MO) optimization model for partner selection in a market-oriented dynamic collaboration (DC) platform of cloud providers (CPs) to minimize the conflicts among providers that may happen when negotiating among providers. The model not only uses their individual information (INI) but also past collaborative relationship information (PRI) for partner...
In this paper, we present a novel combinatorial auction (CA) based cloud market model that facilitates dynamic collaboration (DC) among cloud providers (CPs) for providing composite/collaborative cloud services to consumers and hence can address the interoperability and scalability issues for cloud computing. Also to minimize the conflicts that may happen when negotiating among providers in a DC platform,...
Privacy and data protection have become a critical issue in recent years. Not surprisingly, many technologies have been proposed to support privacy data management. The widely used access control model, role based access control (RBAC), significantly simplifies the specification and management of data. In this paper we proposed a privacy-aware system to improve the performance in RBAC, which properly...
In Web environment, multiple Web service(WS)s may provide similar functionalities with different nonfunctional property values (e.g. different QoS metrics). Quality of service (QoS) metrics of WSs are critical factors to select appropriate WSs execution path in WSs composition as it requires expensive computation cost to find out appropriate execution path in Web environment, i.e O(MN) assuming that...
