In designing a video broadcasting system, the delay preference of a user is traditionally regarded as unknown. In fact, such preference can be known upon user’s arrival by employing some techniques such as i) delay-dependent charging, where users are offered different levels of pay-per-view (PPV) depending on the maximum delay they are willing to tolerate; or ii) reservation, where a user speci...

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 ...

The IEEE 802.16e Broadband Wireless Access (BWA) system is developed to cater for rapidly growing requirement for multimedia wireless services. Since the heterogeneous services provided by the system are connection-oriented, Call Admission Control and required resource reservation mechanisms are needed to achieve desired quality of service (QoS). Traditional admission control algorithms are bas...

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...

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...
