This is related to reserve the resource in advance in “Workflow scheduling” of cloud computing. The problem with the traditional allocation of resource is that the resource may be not available when needed and the requested application will be rejected. To overcome this problem, an advance reservation technique is used. Various techniques are used to reserve the resource in advance such as ECA ...

Grids denote a promising concept to pool computer resources for joint computations. Facing increasingly more complex and demanding resources, Grids are deemed the solution to those problems by a more efficient and flexible usage of already existing resources. From a technical perspective Grid middleware have made significant progress. While in former implementations it was only possible to shar...

This paper presents call admission control and bandwidth reservation schemes in wireless cellular networks that have been developed based on assumptions more realistic than existing proposals. In order to guarantee the handoff dropping probability, we propose to statistically predict user mobility based on the mobility history of users. Our mobility prediction scheme is motivated by computation...

Online reservation systems have grown over the last recent years to facilitate the purchase of goods and services. Generally, reservation systems require that customers provide some personal data to make a reservation effective. With this data, service providers can check the consumer history and decide if the user is trustable enough to get the reserve. Although the reputation of a user is a g...

In this paper, we study Distributed Admission Control (DAC) procedure for anycast flows with QoS requirements. We focus on algorithms that perform destination selection, which is critical in anycast. Several algorithms are proposed. These algorithms differ from each other in their dependence on system status information. We also address the issue of resource reservation and re-trial control in ...

The study block opens up with the already found oil reservation, through comprehensive analysis to seismic, well logging, log and core data, collate stipulate system of fault, then make sure source fault; Meanwhile we use Geo-Office Jason multiply technology, launch micro faces single sand body spread research. result shows that, mostly have 4 kinds reservation: fault-lithologic, fault block, f...

Soft handoff techniques in direct-sequence code-division multiple-access (DS-CDMA) systems provide mobile calls with seamless connections between adjacent cells. Channel reservation schemes are used to give high priority to more important soft handoff attempts over new call attempts. However, since the number of soft handoff attempts varies according to environmental conditions, fixed reservati...
