Proceedings ArticleDOI
Design of multimedia Web server using a neuro-fuzzy framework
TL;DR: The proposed neuro-fuzzy scheduler (NFS) makes an intelligent compromise among multicriteria by properly combining some scheduling heuristics and can dynamically adjust to the varying work-load quite well.
Proceedings ArticleDOI
Real time resource allocation for multimedia object communication
TL;DR: A dynamic bandwidth management scheme for asynchronous LANs that uses the concept of time division multiple access (TDMA) to ensure quality of service (QoS) for multimedia applications and a framework for graceful degradation of play-out quality of multimedia objects is proposed.
Knowledge for Biological
TL;DR: A multilayered architecture and spatiotemporal models for searching, retrieving, and analyzing highthroughput biological imaging data are presented.
Proceedings ArticleDOI
Ensuring quality of service for multimedia applications in a LAN environment
TL;DR: Experimental results reveal that the performance of the proposed scheme is substantially better than that of the random access mechanism, and transmission rates for multimedia hosts are improved significantly with low jitter variations in media streams.

PRISM: A Hierarchical Intrusion Detection Architecture for Large-Scale Cyber Networks
TL;DR: In this article, the authors present a hierarchical intrusion detection architecture that uses a novel attacker behavior model-based sampling technique to minimize the real-time traffic processing overhead, which can detect complex multi-stage attacks in realtime by processing the immense amount of traffic produced by present-day networks.
