All-optical packet switching has been intensively investigated in recent years as an alternative to static, crossconnect based networks. Several switch architectures have been proposed, all of them using buffers made of fibre delay lines. The paper address ...
In this paper we consider the online ftp problem. The goal is to service a sequence of file transfer requests given bandwidth constraints of the underlying communication network. The main result of the paper is a technique that leads to algorithms that opt ...
The P-Grid approach enables distributed search and replication. Gridella, a P2P system based on P-Grid, improves on Gnutella’s search performance while reducing bandwidth requirements. Fu ...
Performance differences in the growing number of electromagnetic (EM) sensing systems designed to predict soil water content from dielectric permittivity estimates suggests the need for a standardized characterization methodology. The objectives of this st ...
We address the design of complex monolithic systems, where processing cores generate and consume a varying and large amount of data, thus bringing the communication links to the edge of congestion. Typical applications are in the area of multi-media proces ...
Abstract—In this paper, a model is proposed to analyze the influence of timing imperfections on ultra-wide bandwidth (UWB) time-hopping spread-spectrum (TH-SS) signaling schemes, where N pulses are coherently added to increase the received signal-tonoise r ...
We consider the design of optimal strategies for joint power adaptation, rate adaptation and scheduling in a multi-hop wireless network. Most existing strategies control either power and scheduling, or rates and scheduling, but not the three together as we ...
A dual-polarized, broadband antenna made up of two single-polarized dipoles is presented. The antenna is mounted on a ground plane to produce a low-profile structure. Two fractal-like elements are used, but a very wide bandwidth is only achieved by making ...
We consider the problem of distributing high-quality video signals over IP multicast in large Local Area Networks (LANs), under real-time delay constraints, and with software-only processing. In a large LAN (such as the network of a university campus, or t ...
We present an automatic content-based video transcoding algorithm which is based on how humans perceive visual information. The transcoder support multiple video objects and their description. First the video is decomposed into meaningful objects through s ...
