Deterministic radio broadcasting at low cost

Networks, 2001
AbstractWe consider distributed deterministic broadcasting in synchronous radio networks. A node receives a message in a given round if and only if exactly one of its neighbors transmits. The source message has to reach all nodes. We assume that nodes do not know the network topology or even their immediate neighborhood. (Such networks are calledad hoc.

Radio broadcasting

1995
Abstract In a short space it is very difficult to do justice to so wide a subject as broadcasting, which embraces many engineering and operational disciplines. Therefore I shall try to describe the main differences between broad casting and the rest of the sound recording industry.

Fast broadcasting and gossiping in radio networks

Journal of Algorithms, 2002
Summary: We establish an \(O(n\log^2 n)\) upper bound on the time for deterministic distributed broadcasting in multi-hop radio networks with unknown topology. This nearly matches the known lower bound of \(\Omega(n\log n)\). The fastest previously known algorithm for this problem works in time \(O(n^{3/2})\).

Asynchronous Broadcast in Radio Networks

2004
We study asynchronous packet radio networks in which transmissions among nodes may be delayed. We consider the task of broadcasting a message generated by the source node. The timing of arrivals of messages is controlled by adversaries. We consider three different adversaries.

Fault-Tolerant Broadcasting in Radio Networks

Journal of Algorithms, 2001
Summary: We consider broadcasting in radio networks that are subject to permanent node failures of unknown location. Nodes arc spread in a region in some regular way. We consider two cases: nodes are either situated at integer points of a line or they are situated in the plane, at grid points of a square or hexagonal mesh.

A diaphragmless microphone for radio broadcasting

Journal of the American Institute of Electrical Engineers, 1923
THE broadcasting of regular programs of entertainment and instruction was begun in the Fall of 1920. It was not long before the service became quite generally used, although at first this was due to its novelty. Judged by present standards, the character of the programs rendered, and the quality of modulation attained, was susceptible to great ...

Distributed Broadcast in Unknown Radio Networks

SIAM Journal on Computing, 2010
We consider the problem of broadcasting in an unknown radio network modeled as a directed graph $G=(V,E)$, where $|V|=n$. In unknown networks, every node knows only its own label, while it is unaware of any other parameter of the network, including its neighborhood and even any upper bound on the number of nodes. We show an $\mathcal{O}(n\log n\log\log

Community Radio Broadcasting

2020
Community radio broadcasting in Japan uses the frequency of ultrashort wave broadcasting. So, it is also called community FM because of FM broadcasting. Since the community radio broadcasting regulations were set in the broadcasting law in 1992, the number of community radio stations has reached 320 nationwide as of July 2018, and the number will ...
