The advancements in distributed computing have driven the emergence of service-based infrastructures that allow for on-demand provision of ICT assets. Taking into consideration the complexity of distributed environments, significant challenges exist in providing and managing the offered on-demand resources with the required level of Quality of Service (QoS), especially for real-time interactive multimedia...
In order to enable interactive applications to benefit from the offerings of the Cloud paradigm, factors such as QoS and event handling need to be taken into consideration in the development of new platforms. In this paper we propose a hierarchical Execution Management System Architecture that enables the execution of real-time interactive applications on SOIs by providing the required QoS levels.
This paper addresses the problem of optimum allocation of distributed real-time workflows with probabilistic service guarantees over a grid of physical resources made available by a provider. The discussion focuses on how such a problem may be mathematically formalised, both in terms of constraints and objective function to be optimized, which also accounts for possible business rules for regulating...
Composite applications consisting of multiple mobile services require intricate service management and security infrastructures. Grid based approaches to service management can be applied to provide such infrastructures to both support and secure users and services in these composite mobile applications. The Akogrimo project has applied WSRF based Service Oriented toolkits as the core element of a...
This paper deals with the problem of scheduling workflow applications with quality of service (QoS) constraints, comprising real-time and interactivity constraints, over a service-oriented grid network. A novel approach is proposed, in which high-level advance reservations, supporting flexible start and end time, are combined with low-level soft real-time scheduling, allowing for the concurrent deployment...
In the world of pervasive computing the status of each device (idle or active) could be dynamically altered and multimedia content is added or removed dynamically. The traditional approaches that create static multimedia indices are inappropriate. To address this problem, a new technique for indexing multimedia content in pervasive environments, is proposed. This technique is based on an innovative...
