This paper considers an overbooking problem with multiple reservation and inventory classes, in which the multiple inventory classes may be used as substitutes to satisfy the demand of a given reservation class (perhaps at a cost). The problem is to jointly determine overbooking levels for the reservation classes, taking into account the substitution options. Such problems arise in a variety of...

This article proposes an integrated framework for adaptive QoS provision in IEEE 802.16e broadband wireless access networks based on cross-layer design. On one hand, an efficient admission control (AC) algorithm is proposed along with a semi-reservation scheme to guarantee the connection-level QoS. First, to guarantee the service continuity for handoff connections and resource efficiency, our s...

This paper explores the need, development of computerized passenger reservation system for Indian railways. The passenger reservation system is based on online transaction processing. It was given the name Integrated Multitrain Passenger REServation System (IMPRESS) which later developed into single image system called Countrywide Network Of Computerized Enhanced ReservaTion (CONCERT). Then thi...

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...

We propose a unified framework consisting of a differential bandwidth reservation (DBR) algorithm and a Quality of Service (QoS)-aware admission control scheme to provide QoS guarantees to on-going connections in cellular networks. The differential bandwidth reservation policy uses a sector of cells in making the bandwidth reservation for accepting a new call. Based on the distance of the targe...

In terms of delivery of compressed videos, two service categories are frequently considered, namely, deterministic and statistic. It is a general belief that the statistic service can achieve more efficient bandwidth utilization than the deterministic one due to its statistically multiplexing streams. In this paper, we, however, investigate the possibility of applying the multiplexing principle...
