In this paper, we investigate the e ectiveness of applying type-II hybrid ARQ schemes to the transmission of MPEG-2 encoded video streams over xed wireless links in broadband xed ...
We describe the implementation and experimental evaluation of a fault-tolerant leader election service for dynamic systems. Intuitively, distributed applications can use this serv...
A key issue in utility computing environments, such as utility Grids, is the provisioning, orchestration and allocation of resources to services. In these environments, providers ...
In Web services, a framework for the separation of authentication (IdP) and services (SP) has been proposed and actually deployed. In this framework, quality of information provide...
Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As resources are limited (particularly in the...
