In this paper we have proposed a practical approach for multicasting in wide area networks. It is a modification of the classical RPF approach. Though our approach is a modification of the RPF, it retains all the advantages of the RPF method and has an additional important advantage of efficient utilization of bandwidth by reducing the number of duplicate packets generated when compared to RPF....

In this paper, an efficient reservation-based handoff control scheme is proposed for improving bandwidth utilization in multimedia mobile cellular networks. In the proposed scheme, the network reserves resources for handoff traffic based on both the probabilities of a call moving into its neighboring cells and the traffic loading distributions in those neighbors. An analytical model is develope...

A number of techniques have been developed for maximizing disk bandwidth utilization in media servers, including disk arm scheduling and data placement ones. Instead, in this paper we focus on how to eeciently utilize the available memory. We present techniques for best memory use under diierent disk policies, and derive precise formulas for computing throughput and memory use. We show that wit...

On-demand broadcast is an effective data dissemination approach in mobile computing. Recently, a large number of applications have been developed in broadcast systems equipped with multiple channels. In this study, we investigate the data scheduling issues arising in multichannel on-demand broadcast. The bandwidth utilization problem, which renders a poor performance of existing algorithms, is ...

Web crawling is a popular technique for data collection among researchers, practitioners and scholars. One of the major challenges web crawling techniques often face is the inefficient utilization of bandwidth, which results in unbalanced crawl between different sites. In this paper, we described a probabilistic model to improve the crawling distribution of the overall sample. The probabilistic...

In this paper, we present a scalable pricing model for dynamic bandwidth allocation combined with simulation scenarios that demonstrate different aspects of a scalable service delivery model and at the same time guarantees a good level of resource utilization. The model allows for increasing the revenue while maintaining an acceptable level of quality of service (QoS) for users. Simulation resu...

Prefetch can be used to reduce the query latency and improve the bandwidth utilization of cache invalidation schemes. However, prefetch consumes power. In this paper, we propose a power-aware cache management to address this issue. Based on a novel prefetch-access ratio concept, the proposed scheme can dynamically optimize performance or power based on the available resources and performance re...

This paper presents a comprehensive procedure to design multimedia storage systems for on-demand playback. The design stresses effective utilization of disk bandwidth with minimal data buffer to minimize overall system costs. The design procedure is most distinctive in the following two aspects: 1. It bases on a tight upper bound of the lumped disk seek time for the Scan disk scheduling algorit...

The efficient utilization and management of bandwidth in broadband networks is of paramount importance since bandwidth costs are likely to dominate network operational costs, especially in the wide area scenario. However, relatively little attention has been given to this issue in developing the current schemes for the transport of Internet data traffic over ATM. In this paper we describe a ban...
