We consider the problem of how to enable the streaming of live video content from a single server to a large number of clients. One recently proposed approach relies on the cooperation of the video clients in forming an ...

This paper presents a suite of randomized broadcast protocols for the problem of broadcasting a message in multi-hop radio networks. The protocols are compared with the randomized broadcast protocol by Bar-Yehuda et ...

The importance of computer applications and telecommunication services relying on efficient multi-destination communication is growing rapidly. It is now likely that a significant portion of the overall traffic in ...

In most proposed architectures for Video-On-Demand (VOD) systems, the customers are serviced individually by allocating and dedicating a trans- mission channel and a set of video server resources to each customer. ...

Server replication is a key approach for maintaining user-perceived quality of service within a geographically wide-spread network. The anycasting communication paradigm is designed to support server replication by ...

IP multicasting allows a source to define a multicast group address and receivers can dynamically join and leave this group. Currently the propagation of multicast packets is controlled by two scoping methods: TTL scoping ...

The recent growth in use of the World Wide Web in the Internet has caused a significant increase in the demand placed on Web servers. This increased load results in noticeably longer response times for users. We propose ...

The continuing merger of computer and communication technologies is leading to a new computing/communications infrastructure of unprecedented magnitude, enabling new applications with broad economic and social impact. Yet, ...

Power management is a critical issue in wireless ad hoc networks where the energy supply is limited. In this paper, we investigate a routing paradigm, Message Ferrying (MF), to save energy while trading off data delivery ...

Delay tolerant networks (DTNs) are a class of emerging networks that are subject to frequent and long-duration partitions. Due to intermittent connectivity, DTNs might be significantly limited in supporting application ...
