Check pointing has been widely adopted in support of fault-tolerance and job migration, with checkpoint files preferably kept also at remote storage to withstand unavailability/failures of local nodes in networked systems. Lately, I/O bandwidth to remote storage becomes the bottleneck for check pointing on a large-scale system. This paper proposes an adaptive incremental check pointing (AIC), aiming...
Existing virtual clusters and computer clouds usually depend on small groups of (or even single) data repositories for their virtual machine and software deployments. This paper proposes a Peer-to-Peer (P2P)-based approach for publishing, querying, and deploying both virtual machine (VM) images and application-specific packages, dubbed the P2P Virtual Cluster Deployment System (PVC-DS). The approach...
With various wireless technologies developed, a ubiquitous and integrated architecture is envisioned for future wireless communication. An important optimization issue in such an integrated system is how to minimize the overall communication cost by intelligently utilizing the available heterogeneous wireless technologies while, at the same time, meeting the quality-of-service requirements of mobile...
