With the popularity of broadband networks, video streaming grows rapidly in the Internet. By the deployment of caching proxies, the backbone bandwidth can be saved significantly. In this paper, we propose a packet-based caching architecture for video streaming. The proposed caching scheme is based the streamed packets instead of video files and the consideration of packet loss recovery. We also...

The Simultaneous Optical Multiprocessor Exchange Bus (SOME-Bus) is a low-latency, high-bandwidth interconnection network that directly links arbitrary pairs of processor nodes without contention, and can efficiently interconnect over one hundred nodes. Each node has a dedicated output channel and an array of receivers, with one receiver dedicated to every other node’s output channel. The SOME-B...

Cooperative caching is an important technique to support efficient data dissemination and sharing in Mobile Ad hoc Networks (MANETs). In order to ensure valid data access, the cache consistency must be maintained properly. Many existing cache consistency maintenance algorithms are stateless, in which the data source node is unaware of the cache status at each caching node. Even though stateless...

As people spend more time watching and sharing videos online, it is critical to provide users with a satisfactory quality of experience (QoE). Leveraging the in-network caching named-based routing features in Named Data Networks (NDNs), our paper aims improve user through caching. We propose graph neural network-gain maximization (GNN-GM) cache placement algorithm. First, we use GNN model predi...

The current explosion of video traffic compels service providers to deploy caches at edge networks. Nowadays, most caching systems store data with a high programming voltage corresponding the largest possible ‘expiry date’, typically on order years, which maximizes cache damage. However, popular videos rarely exhibit lifecycles longer than couple months. Consequently, can instead be adapted fit...

We study the content placement problem for cache delivery video-on-demand systems under static random network topologies with fixed heavy-tailed video demand. The performance measure is the amount of server load; we wish to minimize the total download rate for all users from the server and maximize the rate from caches. Our approach reduces the analysis for multiple videos to consideration of d...

The purpose of our on going research would be to track entities, which enter their field of vision over the sensor network. Based on their sightings, they maintain a dynamic cache that can be queried by a base stationa stationary or fixed node. Since transmitting messages consumes a lot of energy, as against local processing and moreover the limited energy in sensor node does not allow heavy du...

In database cracking, a database is physically self-organized into cracked partitions with cracker indices boosting the access to these partitions. The AVL Tree is the data structure of choice to implement cracker indices. However, it is particularly cache-inefficient for range queries, because the nodes accessed only for a few times (i.e, “Cold Data”) and the most accessed ones (i.e, “Hot Data...

Adaptive streaming based on DASH offers personalized video experience and smooth playback by allowing dynamical adjustments of the bitrate to variations network conditions. This is especially important for current future Internet applications, including emerging ones such as virtual reality-based, adaptive plays a key role in providing high quality viewing experience, limited bandwidth delivery...
