This letter proposes a broadcast scheme for use in ad hoc networks using variable-range transmission power. Preserving energy and ensuring a high delivery ratio of broadcast packets are crucial tasks for broadcasting in ad hoc networks. Using individual broadcast relaying nodes to dynamically vary the transmission range can help saving power and reduce interference during communication. We anal...

There is an increased interest in using broadcast disks to support mobile access to realtime databases. However, previous work has only considered the design of real-time immutable broadcast disks, the contents of which do not change over time. This paper considers the design of programs for real-time mutable broadcast disks | broadcast disks whose contents are occasionally updated. Recent sche...

This discourse analysis aimed to investigate how language is used in news broadcast through the use of Fairclough’s three dimensional model. Data revealed on its textual level that broadcast, like any form discourse, also positive adjectives, negative adjectives and disjunctive syntax. Various strategies were employed by producers order realize communicative end. News media carries an important...

Classical distributed protocols like broadcast or multi-party computation provide security as long as the number of malicious players f is bounded by some given threshold t, i.e., f ≤ t. If f exceeds t then these protocols are completely insecure. We relax this binary concept to the notion of two-threshold security: Such protocols guarantee full security as long as f ≤ t for some small threshol...

Data broadcasting as a means of efficient data dissemination is a key technology facilitating ubiquitous computing. For this reason, broadcast scheduling algorithms have received a lot of attention. However, all existing algorithms make the core assumption that the data items to be broadcast are immediately available in the transmitter’s queue, ignoring the key role that the disk subsystem and ...

Reliable broadcast protocols are a fundamental building block for implementing replication in fault-tolerant distributed systems. This paper addresses secure service replication in an asynchronous environment with a static set of servers, where a malicious adversary may corrupt up to a threshold of servers and controls the network. We develop a formal model using concepts from modern cryptograp...
