Cloud computing enables service sharing in a massive scale via network access to a pool of configurable computing resources. It has to allocate resources adaptively for tasks and applications to be executed effectively and reliably in a large scale, highly heterogeneous environment. Resource allocation in cloud computing is an NP-hard problem. In this study, the authors conduct a reliability analysis...
The security problem in multihop wireless networks is more severe than that in wired networks since its transmission media is the unprotected air. In this paper, we show how to increase the effective throughput via carefully choosing the multi-path routing for given source and destination nodes, where we call the total packets from the mesh routers to the gateway nodes that are not attacked by an...
Unlike convectional omni-directional sensors that always have an omni-angle of sensing range, directional sensors may have a limited angle of sensing range due to technical constraints or cost considerations. A directional sensor network consists of a number of directional sensors, which can switch to several directions to extend their sensing ability to cover all the targets in a given area. Power...
