Efficient Network Utilization for Multimedia Wireless Networks
In this paper, we present an access scheme to satisfy the QoS requirements for two classes of traffic during the contention phase of packet-switched wireless communications. In the proposed scheme, different classes of users contend with other users for resources based on controlled class-dependent permission probabilities. We prove that our algorithm is stable for a large class of arrival proc...
متن کاملMultimedia Networks and Communication
4 Paul Baran from the RAND Corporation first proposed the notion of a distributed communication network in 1964 [33] [42]. The aim of the proposal was to provide a communication network that could survive the impact of a nuclear war and employed a new approach to data communication based on packet switching. The Department of Defense (DoD) through the Advanced Research Projects Agency (ARPA) co...
متن کاملAgent-Based Intelligent Multimedia Broadcasting within MPEG-21 Multimedia Framework
ETRI Journal, Volume 26, Number 2, April 2004 It is expected that an intelligent broadcasting service (IBS) will be able to provide broadcast programs based on user preference and program-associated information (metadata) in order to assist users in easy navigation of the program content being broadcast. In this way, users will be able to access program content anytime, anywhere, and in the man...
متن کاملUser Agent Migration Policies in Multimedia Wireless Networks
Multimedia wireless networks often employ network based user agents as proxies for mobile users. In this paper, we consider a fundamental question in the design of these networks: should the user agents migrate and if so, what are good user agent migration policies? We first introduce a general framework for malysing user agent migration policies. We then highlight, through analysis and simulat...
متن کاملProposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
