In broadcasting, information originally held in one node of a communication network (called the source) has to be transmitted to a11 other nodes. In a unit of time, every node which already got the source message can transmit it to one neighbor. In classical broadcasting, the choice of neighbors to be informed by a node and the order in which they are informed may depend on the source. Thus, no...

This chapter studies the cooperative broadcasting in wireless networks. We especially focus on multistage cooperative broadcasting in which the message from a source node is relayed by multiple groups of cooperating nodes. Interestingly, group transmissions become beneficial in the case of broadcasting as opposed to the case in traditional networks where receptions from different transmitters a...

We provide a formal framework for studying broadcasting schemes and design a family of schemes for broadcasting popular videos, called the Greedy Diskconserving Broadcasting (GDB) scheme. We analyze the resource requirements for GDB, i.e., the number of server broadcast channels, the client storage space, and the client I/O bandwidth required by GDB. The analysis shows that GDB exhibits a trade...

In this paper, we investigate the fundamental properties of broadcasting in mobile wireless networks. In particular, we characterize broadcast capacity and latency of a mobile network, subject to the condition that the stationary node spatial distribution generated by the mobility model is uniform. We first study the intrinsic properties of broadcasting, and present the RippleCast broadcasting ...

This article seeks to establish connections between histories of education and media by examining long-term institutional structural factors. In order a role for broadcasting in schools, the BBC formed relationship with educational world through advisory machinery called Central Council School Broadcasting (CCSB), later reconstituted as (SBC). key period school broadcasting’s development, 1935 ...

The AM Signalling System (AMSS), now a published ETSI standard [2], has been designed within the DRM Coding and Multiplexing (DRM-CM) group. It uses low bitrate phase modulation of the AM carrier to add a small amount of digital information to existing analogue AM broadcasts on short-, mediumand long-wave, giving similar functionality to that provided by the Radio Data System (RDS) on the FM ba...

Harmonic broadcasting is a broadcasting scheme to reduce the bandwidth requirement in video-on-demand service where a video is divided into segments of equal size and each segment is repeatedly transmitted over a number of channels having bandwidth that follows a harmonic series. As the bandwidth of channels differ from each other and a user can join at any time to these multicast channels, a s...

This work presents a broadcasting protocol for interactive video-on-demand service. The proposed broadcasting allows the user to play the video-cassette-recorder (VCR) functions which includes the limited fast-forwarding capability. Consider a film S is divided into n equal parts {S1, S2, ..., Sn} and played through k channels. The user simultaneously downloads the film segments from k channels...
