Patching: a multicast technique for true video-on-demand services
TLDR
This paper is able to tiate the service latency and improve the efficiency of mtiticast at the same time, and indicates convincingly that Patching offers .wbstanti~y better perforrnace. Expand

TLDR
A peer-to-peer technique called ZIGZAG for single-source media streaming is designed, which allows the media server to distribute content to many clients by organizing them into an appropriate tree rooted at the server that has a height logarithmic with the number of clients and a node degree bounded by a constant.

Skyscraper broadcasting: a new broadcasting scheme for metropolitan video-on-demand systems
TLDR
This study investigates a novel multicast technique, called Skyscraper Broadcasting (SB), for video-on-demand applications, and is able to achieve the low latency of PB while using only 20% of the buffer space required by PPB. Expand

  • 7 January 2004
TLDR
In Zigzag, the multicast tree has a height logarithmic with the number of clients, and a node degree bounded by a constant, so that the end-to-end delay is kept small. Expand
P2VoD: providing fault tolerant video-on-demand streaming in peer-to-peer environment
TLDR
The novel ideas in this paper are the use of a new caching scheme at clients, and the introduction of generation for better client management, which outperforms a recently proposed system in a number of important performance metrics. Expand
Processing range-monitoring queries on heterogeneous mobile objects

  • 24 August 2004
TLDR
The study shows that the new technique is many times better in reducing mobile communication and server processing costs and also makes the new approach highly adaptive to the heterogeneity of mobile objects. Expand
Chaining: a generalized batching technique for video-on-demand systems
TLDR
A new batching mechanism called chaining is examined, which allows the server to serve a "chain" of client stations using a single data stream to reduce the long access latency. Expand
Real-time processing of range-monitoring queries in heterogeneous mobile databases
TLDR
An efficient technique for real-time processing of range-monitoring queries that can be highly scalable in supporting location-based services in a wireless environment that consists of a large number of mobile devices. Expand
BroadCatch: a periodic broadcast technique for heterogeneous video-on-demand
TLDR
Using an incremental channel design at the server side, and a specific broadcast schedule, users can choose among a range of bandwidths to use to download the video at the cost of their access latency and not to the video quality. Expand
Optimizing patching performance
TLDR
The notion of patching window is introduced, and the optimal technique outperforms the existing schemes by a significant margin, and is also up to two times better than the best Piggybacking method which provides data sharing by merging the services in progress into a single stream by altering their display rates.
