With the increase in the bandwidth needs of network service, the customer requirements for Quality of Service (QoS) are also higher. Although the QoS guarantees can be offered by signing the Service Level Agreement (SLA), the costs of infrastructures are increased as well. This paper proposes a shortest path algorithm based on SLA, combined with the resource allocation for virtual networks (VNs)....
The necessity of balancing the obtained performance with the energy consumed is an emerging ambition for cloud computing research. Performance in cloud computing is defined through Service Level Agreement contracts between the cloud provider and cloud customer, being a projection of the customer's perspective on the service offered by the cloud provider. Although more and more research efforts go...
In a clustering-based MANETs, task allocation has posed increasing research challenges because the needs of management and coordination are accentuated by complicated demands of cluster members. A self-adaptive method of task allocation is designed to facilitate self-planning and self-negotiation for nodes during tasks being distributed and executed. The method is composed of two parts: for one part,...
Applications of high-quality multimedia embedded systems (HQMES) contain concurrent functionality pieces; they may have a flexible structure consisting of services, components, or tasks. This allows applications to offer different execution possibilities to provide a same (or different) output quality. Since multimedia applications are typically greedy resource consumers, they may interfere one another's...
Media processing in high-quality multimedia embedded systems (HQMES) has real-time constraints. Timely processing and rendering of video frames and audio samples is essential to meet user expectations. The nature of incoming media suffers unforeseen variations which have different resource requirements. Therefore, HQMES have to integrate policies for efficiently and smoothly adapting to these changes...
We present the case for DTNServ, a service class framework for the delay tolerant network architecture, that can greatly improve the communications interface between DTN applications and the network implementation. Through this framework, user applications can be efficiently informed about the state of the network and communicate their needs, allowing for more informed provisioning and scheduling...
