We deal with a reservation-based cloud service broker (R-CSB). The main role of the R-CSB is to provide application execution services or Softwareas-a-Service. The R-CSB makes a profit by an arbitrage between cloud service consumers and providers, and service fees from the consumers. In this paper, we first present detail concepts and architecture of the R-CSB. Also, to reduce the VM leasing co...

Many Mobile devices today access the data from the remote servers through the user generated queries. Processing of these queries should be done before the desired content to be delivered is identified. In this manner, when the processing is done the process will cut down the battery stand-by time there by making user without mobile when actually required also the problem may arise at the serve...

Should a monopolistic vendor adopt the selling model or the leasing model for information goods or services? We study this question in the context of consumer valuation depreciation. Using a two-period game-theoretic model, we consider two types of consumer-side valuation depreciation for information goods or services: vintage depreciation and individual depreciation. Vintage depreciation assum...

The Internet of Things (IoT) is a vision of the upcoming society. It can provide pervasive communication between two or more entities using 4G-LTE (Long Term Evolution) communication technology. In 4G-LTE networks, there are two important problems: helping manage the spectrum demands of IoT devices and achieving much more revenue with the limited resource. This paper proposes a pricing framewor...

With wireless network virtualization, Mobile Virtual Network Operators (MVNOs) can develop new services on a low-cost platform by leasing virtual resources from mobile network owners. In this paper, we investigate a two-stage spectrum leasing framework, where an MVNO acquires radio spectrum through both advance reservation and on-demand request. To maximize its surplus, the MVNO jointly optimiz...

Leasing computational resources for on-demand computing is now a viable option for providers of network services. Temporary spikes or lulls in demand for a service can be accommodated by flexible leasing arrangements. From the service provider’s perspective, the problem is how many resources to lease and for how long. In this paper we formulate and solve the resource leasing problem for the cas...

Conclusions ~~ The limited stable storage available in mobile-computing environments can make traditional checkpointing and message logging umuitable. Since storage on a mobile liost is not considered stable, most protocols designed for these environments save the checkpoints on base stations. Previous approaches have assumed that the base station always has sufficient disk space for storing ch...
