Cloud computing allow the users to efficiently and dynamically provision computing resource to meet their IT needs. Cloud Provider offers two subscription plan to the customer namely reservation and on-demand. The reservation plan is typically cheaper than on-demand plan. If the actual computing demand is known in advance reserving the resource would be straightforward. The challenge is how to ...

Web services can be used to automate business activities that span multiple enterprises over the Internet. Such business activities require a coordination protocol to reach consistent results among the participants in the business activity. In the current state of the art, either classical distributed transactions or extended transactions with compensating transactions are used. However, classi...

Timely imaging examinations are critical for stroke patients due to the potential life threat. We have proposed a contract-based Magnetic Resonance Imaging (MRI) reservation process [1] in order to reduce their waiting time for MRI examinations. Contracted time slots (CTS) are especially reserved for Neural Vascular Department (NVD) treating stroke patients. Patients either wait in a CTS queue ...

In this paper we study the optimal sourcing decisions of a multi-product newsvendor prior to the selling season of the products. To satisfy the uncertain demands, the newsvendor can either utilize speculative production, or anticipatively reserve capacity. During the selling season when demand has become known, the newsvendor can utilize its reserved capacity and reactively satisfy demand uncov...

Emerging communication-intensive applications such as multimedia teleconferencing require signiicant networking resources for eecient operation. In an indoor mobile computing environment, limited wireless resources and user mobility require eeective resource reservation algorithms. These requirements demand an eecient advance reservation algorithm in order to minimize handoo call dropping while...

One of the requirements for seamless mobility is efficient resource reservation and context transfer procedures during handoff. If context transfer and resource reservation can occur prior to handoff continuation of the same level of service as at the previous connection point is possible. Resource reservation is required to be nonaggressive for optimal use of limited bandwidth and a low call-b...

In this paper we present the efficient burst reservation protocol (EBRP) suitable for bufferless optical burst switching (OBS) networks. The EBRP protocol is a two-way reservation scheme that employs timed and in-advance reservation of resources. In the EBRP protocol timed reservations are relaxed, introducing a reservation time duration parameter that is negotiated during call setup phase. Thi...

Reservation Wages, Search Duration, and Accepted Wages in Europe This paper uses data from the European Community Household Panel, 1994-99, to investigate the arrival rate of job offers, the determinants of reservation wages, transitions out of unemployment, and accepted wages. In this exploratory treatment, we report that the arrival rate of job offers declines precipitously with jobless durat...

To enhance the saturation throughput in Vehicular Ad-hoc NETworks (VANETs), one of solutions is a variable Control CHannel Interval (CCHI) multichannel Medium Access Control (MAC) scheme. Recently, the HER-MAC is more reliable and efficient in both the safety message broadcast and the service channel utilization. HER-MAC which requires lower time for reservation period than IEEE 1609.4 improves...
