The WiMedia specifications for high data rate ultra-wideband communication is an emerging protocol with its first products available on the market. One use case is wireless networking based on the Internet Protocol. Conference rooms or offices can be equipped with access points to provide high speed Internet access. Our intention is to establish WiMedia wireless networks in public transportation vehicles,...
We believe that a market-based resource allocation will be effective in a cloud computing environment where resources are virtualized and delivered to users as services. We propose such a market mechanism to allocate services to participants efficiently. The mechanism enables users (1) to order a combination of services for workflows and co-allocations and (2) to reserve future/current services in...
The future Internet is driven by applications that require simultaneous access to multiple heterogeneous IT resources interconnected by high-speed optical network. Current research on network and IT resource co-allocation address advanced reservations in which each resource-type is optimised independently. However, emerging applications demand a resource co-allocation model that views and optimizes...
In this paper an optimal allocation approach of virtual servers to appropriate data centers is proposed for a network made up of collections of data centers and user groups. The virtual server allocation can be formalized as a linear programming (LP) problem which consists in minimizing the round-trip-times (latencies) between data centers and user groups. Our proposed allocation approach demonstrated...
Desktop grids have emerged as an important methodology to harness the idle cycles of millions of participant desktop PCs over the Internet. However, to effectively utilize the resources of a desktop grid, it is necessary to use scheduling policies suitable for such systems. A scheduling policy must be applicable to large-scale systems involving large numbers of machines. Also, the policy must be fault-aware...
In this paper, we propose a bandwidth-efficient multicast mechanism for heterogeneous wireless networks. We reduce the bandwidth cost of an Internet protocol (IP) multicast tree by adaptively selecting the cell and the wireless technology for each mobile host to join the multicast group. Our mechanism enables more mobile hosts to cluster together and leads to the use of fewer cells to save the scarce...
