We study the security of communication between a single transmitter and multiple receivers in a broadcast channel in the presence of an eavesdropper. We consider several special classes of channels. As the first model, we consider the degraded multi-receiver wiretap channel where the legitimate receivers exhibit a degradedness order while the ...

Parallel Processing Letters, 1998
In this note, we continue the study of messy broadcasting. We obtain exact values for the messy broadcasting time of complete graphs, paths, cycles, and complete d-ary trees. For hypercubes, we obtain exact values for messy broadcasting time under two of the models and present upper and lower bounds for the third model.

[Pra91, Pra92] develop CBS, a CCS-like calculus [Mil89] where processes communicate by broadcasting values along a single channel. These values are hidden or restricted by translation to noise. This paper types CBS and restricts it to processes with a unique response to each input.

Formal Aspects of Computing, 2004
Abstract. Message sequence charts (MSCs) have proven to be a useful modeling technique especially within the requirements analysis phase of software development. MSCs, however, do not support the concept of broadcast communication, which is frequently used in technical applications.

2007 IEEE International Symposium on Information Theory, 2007
The availability of noiseless feedback in an additive white Gaussian noise channel can considerably improve the rate of decay of error-probability with block length. A doubly exponential error decay can be attained even in the presence of an additive interference term non-causally known at the transmitter alone.

Data Broadcasting Solutions for Broadcasters
142nd Technical Conference and Exhibition, 2000With the advent of digital television in the U.S. and worldwide, broadcasters are searching for new opportunities to enhance programming. In addition, many in the industry believe that potential new sources of revenue can be unlocked by providing consumers rich digital content.

On Reversibility and Broadcast
2018Causally consistent reversibility relates reversibility in a concurrent system with causality. Broadcast is a powerful primitive of communication used to model several distributed systems from local area networks, including wireless systems and lately multi-agent systems. In this paper, we study the interplay between reversibility and broadcast, in the

IEEE Transactions on Information Theory, 1972
We introduce the problem of a single source attempting to communicate information simultaneously to several receivers. The intent is to model the situation of a broadcaster with multiple receivers or a lecturer with many listeners. Thus several different channels with a common input alphabet are specified.

The use of radio by the dietitians of the Whittington Hospital and their guest speakers to advise and educate hospital patients on varying aspects of human nutrition, reaching a much larger section of the local population than they could in their usual work, is described.

Broadcast-relay-broadcast channels
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010In this paper, we study the achievable rate regions of broadcast-relay-broadcast channels. The source broadcasts information to the users. A number of parallel relays are used to assist users. Each relay receives information from the source and forwards information to users. The relays also broadcast the forwarded information to all users.
