Information centric network is a special form of computer network that is created for selected or registered nodes only. The information is stored on a central node and all nodes are using it. But the information is available for registered or specific nodes that are attached with it. Information-Centric Networking (ICN) is a current trend in research and development. As it uses centralized inf...

For the last decade, YouTube has consistently been a dominant source of traffic on the Internet. To improve the quality of experience (QoE) for YouTube users, broadband access providers and Google apply techniques to load balance the extraordinary volume of web requests and traffic. We use traceroute-based measurement methods to infer these techniques for assigning YouTube requests to specific ...

In wireless ad hoc networks, designing an energy-efficient routing protocol is a major issue since nodes are energy limited. To address energy issue, we proposed a triangular energy-saving cached-based routing protocol by energy sieving (TESCES). TESCES offered a grid leader election by energy sieving (GLEES), a cache-based grid leader maintenance (CGLM), and a triangular energysaving routing d...

Decentralized, cooperative and large-scale distributed storage systems that consist of a cluster of storage nodes attached with local disks can deliver high resource utilization, high availability and easy scalability. This paper describes the design and prototype implementation of a novel Cluster-Aware Cache (CAC) algorithm that shares memories between nodes in cluster to construct an efficien...

Multiple strategies for caching video objects have been proposed in recent years in order to maximize byte-hit ratio and better cope with large sizes of video objects. Usually, a video proxy-cache will use the same strategy when caching all its objects. We propose a new approach, which enables a proxy-cache to decide which strategy to use on a per object basis. In this context we introduce a ne...

With the growth of bandwidth, video/audio streaming services have become popular, and are considered a future killer application on the Internet. Many researches proposed several possible technologies for streaming services, such as hot-video broadcasting, caching, content delivery network (CDN), and peer-to-peer communications. In the paper, we propose a new streaming architecture combining th...

A video streaming scenario in a wireless Ad Hoc network is considered. In this scenario, nodes are interested in streaming a video available at a single source node. The video will be disseminated throughout the network in a multihop fashion such that some intermediate nodes spend part of their energy for relaying the video. The end-users have different preferences in terms of the amount of ene...

In a video server environment, some video objects (e.g., movies) are very large and are read sequentially. Hence it is not economical to cache the entire object. However, caching random fractions of a multimedia object is not beneecial. Therefore, traditional cache management policies such as LRU are not eeective. The sequential access of pages can be exploited by caching only the intervals bet...

SUMMARY BLAST programs often run on large SMP machines where multiple threads can work simultaneously and there is enough memory to cache the databases between program runs. A group of programs is described which allows comparable performance to be achieved with a Beowulf configuration in which no node has enough memory to cache a database but the cluster as an aggregate does. To achieve this r...
