Cloud federation is a group of aggregated providers, who are mutually cooperating and collaborating to share their resources in order to improve each other services. It has lured the attention of commercial industries towards itself for its effective utilization of cloud resources. Effective management of the resource is very much required in order to increase the profits of an individual service...
Cloud Operators, in order to respond effectively to the QoS requirements of cloud applications, are obliged to apply over-provisioning policies. In general, this tactic leads to severe waste of the available cloud computing resources. Similarly, both Service/Platform Providers and End-Users wish to avoid the extra cost of this over-provisioning tactic and pay only per use, without having to statically...
Sustainability is an important issue with a growing interest. Two ICT technologies provide useful support for the sustainability of industrial systems: service-oriented architecture (SOA) and cyber-physical systems (CPS). SOA has been adopted in a variety of industrial systems due to its integration flexibility and process composability. CPS is a new technology to bring computational intelligence...
Currently, Cloud network operators and service providers are managing server, network and storage resources by various management systems to manage hardware, applications, traffic, and resources monitoring including bandwidth, storage capacity, and throughput utilization. However, these systems are not coordinated with accounting, security and configuration systems to provide end-to-end service management...
This paper presents a model of workflow-oriented virtual enterprise based on policy driven and multi-agent service composition. The cooperation of the members in virtual enterprise will be implemented through the dynamic composition and execution of the services, which is workflow-oriented. Each service has its own policies for selection of the suitable services to achieve the cooperation and composition,...
Complex and mission-critical applications require the use of distributed environments, which will allow their execution in a reliable and cost-efficient way. Grid environments made this case feasible by providing heterogeneous resources. Nevertheless, quality of service (QoS) aspects are regarded as fundamental for enabling the execution of business applications in grids. In that frame, we introduce...
When managing a complex information system for critical activities, reaching an high level of dependability is a key requirement. A central challenge is identifying a set of alternative system configurations to be enforced when particular system situations take place. In large systems, this task requires automation as the administrator can hardly cope with the complexity of all components and their...
In this paper a solution for the facility location problem is presented over an m-commerce infrastructure. An extensive comparison is performed for different scenario. Also delay studies and comparisons on m-transactions are carried out. Numeric and analytical results are presented.
With an increased focus on national security and public safety communications, the US Congress revisited its plan to reclaim television broadcaster frequencies to be reallocated and auctioned by the FCC and it specifically allocated a portion of that spectrum for use by public safety. The FCC was charged with the duty of auctioning this spectrum and licensing it to create a public safety network....
This paper presents the analysis of inter-operator agreements to exchange radio resources in a multi-operator scenario, to improve radio resource usage and operator revenue. The establishment of these agreements increases user perception of the service and reduces churning rate.
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
