In wireless cellular networks, a roaming mobile station (MS) is expected to move from one cell to another. In order to ensure that ongoing calls are not dropped while the owner mobile stations roam among cells, handoff calls may be admitted with a higher priority than newly generated calls. Predictive channel reservation (or pre-reservation) schemes allow the reservation of a channel for an ong...

The manner in which users cross cell boundaries in a cellular network has a high degree of predictability due to temporal and spatial locality in user mobility. This is so because user typically take predictable routes during specific times of the day, and these routes cut across cell coverage areas in an ordered sequence. This mobility information on a per-user basis, referred to as user profi...

We present an innovative totally ordered multicast protocol that is based on reservation of buffers at the destinations and intermediate network bridges, rather than on an acknowledgment strategy. By introducing timestamps into the packets and by using a buffer reservation retract scheme, our protocol not only produces a global total order of packets but also solves the deadlock and starvation ...

There exists a lot of research on the reservation wages of the unemployed as a determinant of unemployment duration. Little is known about the reservation wages of those who are not in the labor force but might be potential labor force returnees, such as Social Security Disability Insurance (DI) beneficiaries. The main objective of this article is to assess what can be learned from the subjecti...

In resource constrained embedded systems, memory reservation, which provides physically contiguous memory allocation to devices (e.g., video decoder and camera), decreases the memory efficiency of the system. The dedicated use of reserved memory by an owner device makes itself more under-utilized when the device is less frequently used. Previous approaches support on-demand reservation to relax...

High-end networking applications such as ecommerce, multimedia, distributed data analysis and advanced collaborative environments feature demanding end-to-end quality of service (QoS) requirements. Due to the heterogeneity exhibited by the Internet, a route from source to destination for such a flow may not be available which is comprised exclusively of QoS supporting path segments. Hence the f...

| In this paper, we propose a bandwidth guaranteed multi-access protocol for broadcast-and-select WDM local networks with a star topology. The proposed protocol is based on a combination of contention and reservation mechanisms for time slotted WDM networks. Every node accesses the data channel by transmitting request packets in minislots on a separate control channel. There are two types of mi...
