We examine routing over two classes of orthogonal information networks. The first is a relay network with orthogonal inputs. The nodes in this network do not broadcast, but communicate to the different nodes via independent inputs. There is multiple access ...

In this paper we present Scalable Position-Based Multicast (SPBM), a multicast routing protocol for ad-hoc networks. SPBM uses the geographic position of nodes to provide a highly scalable group membership scheme and to forward data packets with a very low ...
Although far from optimal, flooding is an in- dispensable message dissemination technique for network- wide broadcast within mobile ad hoc networks (MANETs). As such, the plain flooding algorithm provokes a high number of unnecessary packet rebroadcasts, c ...
We give a lower bound of Ω(n) rounds for broadcasting in a mobile ad hoc network, where n is the number of nodes in the network. A round is the time taken by a node to successfully transmit a message to all its neighbors. It has been shown by Brus ...
Consider a source broadcasting M packets to N receivers over independent erasure channels, where perfect feedback is available from the receivers to the source, and the source is allowed to use coding. We investigate offline and online algorithms that opti ...
Internet communications have traditionally been based on point-to-point connections. This technique is called unicast and allows one sender and one receiver to communicate. The Internet saw the appearance of multicast protocols in the early 90's. Multicast ...
The paper investigates the two main and seemingly antagonistic approaches to broadcasting messages reliably in fault-tolerant distributed systems: the approach based on Reliable Broadcast, and the one based on View Synchronous Communication (or VSC for sho ...
A distributed system is no longer confined to a single administrative domain. Peer-to-peer applications and business-to-business e-commerce systems, for example, typically span multiple local-area and wide-area networks, raising issues of trust, security, ...
This paper presents the design and evaluation of a Striped File I/O (SFIO) library for parallel I/O within an MPI environment. We present techniques for optimizing communications and disk accesses for small striping factors. Using MPI derived datatype capa ...
SFIO, Parallel File Striping for MPI-I/O Emin Gabrielyan EPFL, Computer Science Dept. Peripheral Systems Lab. Emin.Gabrielyan@epfl.ch Abstract This paper presents the design and evaluation of a Striped File I/O (SFIO) library for parallel I/O in an MPI env ...
