Most of previous research in Mobile Ad Hoc Networks (MANETs) concentrated on the development and enhancement of neighbor discovery protocols and routing protocols, which could efficiently discover reliable route between two communication mobile nodes. Data caching addressed two basic issues: cache resolution and cache management. In this paper, we give a review of cache resolution scheme and pe...

In this paper, we describe and evaluate the performance of a caching scheme for ad hoc networks. In this proposal the wireless nodes store the documents they request in a local cache and they can also work as a server for the other wireless nodes if they intercept the forwarding requests and serve the documents requested directly using their local cache. On the other hand, the wireless nodes in...

Data caching strategy for ad hoc networks whose nodes exchange information items in a peer-to-peer fashion. Data caching is a fully distributed scheme where each node, upon receiving requested information, determines the cache drop time of the information or which content to replace to make room for the newly arrived information. These decisions are made depending on the perceived presence of t...

The fundamental problem in developing high-performance multimedia database servers is that images, audio and video data differ from numeric or text data in their characteristics, and hence require different handling techniques. Digital audio and video streams consist of a sequence of media quanta (video frames or audio samples) which convey meaning only when presented contiguously on time. In o...

Multimedia streaming applications such as mobile conferencing, e-learning and mobile cinema are becoming popular for the Internet and mobile devices. Patching can enable a client to receive multicast streaming by listening to ongoing transmission of the same video clip in order to reduce retransmission from the media server. However, multimedia streams multicasting to clients must be stored in ...

Dynamic adaptive streaming over HTTP (DASH) has been widely used in video recently. In DASH, the client downloads chunks order from a server. The rate adaptation function at enhances user?s quality-of-experience (QoE) by choosing suitable quality level for each chunk to download based on network condition. Today networks such as content delivery networks, edge caching contentcentric etc. usuall...

In this study, we propose a mechanism called adaptive failsoft control to address peak traffic in mobile live streaming, using chasing playback function. Although cache system is avaliable support the function for streaming base station and device-to-device communication, request concentration by highlight scenes influences load owing data unavailability. To avoid unavailability, adapted two fe...

Real-time operation of signal processing applications on multimedia RISC processors is often limited by high instruction cache miss rates of direct-mapped caches. In this paper, a heuristic approach is presented which reduces high instruction cache miss rates in direct-mapped caches by code positioning. The proposed algorithm rearranges functions in memory based on trace data so as to minimize ...

Introduction Content networks are usually virtual networks based over the IP infrastructure of Internet or of a corporative network, which use mechanisms to allow accessing a content when there is no fixed, single, link between the content and the host or the hosts where this content is located. Even more, the content is usually subject to reallocations , replications, and even deletions from t...
