Virtual private networks are often used to distribute live content, such as video or audio streams, to a potentially large number of destinations. Streaming caches (also called splitters) are deployed in these multicast systems to allow content distribution without overloading the network. In this paper, we consider two related combinatorial optimization problems that arise in multicast network...

Using proxy cache is a key technique that may help to reduce the loads of the server, network bandwidth and startup delays. Basing on the popularity of clients’ request to segment video,we extend the length for batch and patch by using dynamic cache of proxy cache for streaming media. Present transmission schemes using dynamic cache such that unicast suffix batch, unicast patch, multicast patch...

This article presents a framework for improved and efficient video delivery in scenarios featuring users moving at high speed (e.g., trains), leveraging on dynamic Multi-access Edge Computing (MEC) enabled 5G network capabilities. The is location-aware it allows the content to efficiently follow users, conserving load usage computational resources, by placing virtualized Content Delivery Networ...

A set of applications such as Internet video broadcasts, corporate telecasts, and distance learning require the simultaneous streaming of video to a large population of viewers across the Internet. The high bandwidth requirements and the multitimescale burstiness of compressed video make it a challenging problem to provision network resources for streaming multimedia. For such applications to b...

With the growth of computing power and the proliferation of the Internet, video streaming services become widely deployed. In this paper, we propose, design, implement, and evaluate a proxy caching system for MPEG-4 video streaming services. With our system, the high-quality, low-delay, and scalable video distribution can be accomplished. In our system, a video stream is divided into blocks for...

Increasing the performance of cloud downloading service in a peer-peer network by efficient mode selection method. Using P2P to download video content often faces challenges like high bandwidth requirement, dealing with a huge number of peer requests, resulting in inefficient system performance. The latest premium service to have been developed is the cloud downloading. In this service, cloud s...

Caching in multi-cell networks faces a well-known dilemma, i.e., to cache same contents among multiple edge nodes to enable transmission cooperation/diversity for higher transmission efficiency, or to cache different contents to enable content diversity for higher cache hit rate. In this work, we introduce a partition-based caching to exploit the tradeoff between transmission diversity and cont...

Wireless Sensor Network is application based network. Sensor is divided in different parts. Sink nodes sends query messages based upon temperature suppose. If temperature not arises then no reply is given by the nodes to the sink. But battery degrades due to processing. In cache cooperative networks is deployed in same manners as sensor networks. Nodes are selected on the basis of some assumpti...

Proxy technology is commonly used a t boundaries of ISPs (Internet Service Providers) to reduce the bandwidth requirement in the backbone WAN. By caching portions of a video in a video proxy closed to clients, the video playback quality can be dramatically improved and the problem of insufficient WAN bandwidth is eliminated. In the loss-less nehvork environment, the OC (Optimal Cache) algorithm...

With the fast development of mobile communication technologies and increased capabilities of smart terminals, the multimedia service has become one of the most attractive applications in mobile Internet. And the combination of socialbased mobile multimedia and mobile peer-to-peer (P2P) network has attracted increasing research interests in recent years. However, how to deploy large scale P2P-ba...
