In this paper we address the minimum-energy broadcast problem in multi-hop wireless networks, so that all broadcast requests initiated by different source nodes take place on the same broadcast tree. Our approach differs from the most commonly used one where the determination of the broadcast tree depends on the source node, thus resulting in different tree construction processes for different ...

ÐAll-to-all communication is one of the most dense communication patterns and occurs in many important applications in parallel computing. In this paper, we present a new all-to-all broadcast algorithm in all-port meshes and tori. The algorithm utilizes a controlled message flooding based on a novel broadcast pattern, which ensures a balanced traffic load in all dimensions in the network so tha...

This work presents an Adaptively Secure Broadcast Mechanism (ASBM) based on threats analytics. It defines the security intelligence of a broadcast system comprehensively with a novel concept of collective intelligence. The algorithmic mechanism is analyzed from the perspectives of security intelligence, communication complexity and computational intelligence. The security intelligence of ASBM i...

The purpose of a reliable broadcast protocol is to allow groups of nodes on unreliable broad cast networks to reliably broadcast messages A reliable broadcast protocol must guarantee two properties all of the receivers in a group receive the broadcast messages and each of the receivers orders the messages in the same sequence In an optimistic approach to reliable broadcast protocol a batch ackn...

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorithm, called do...

BACKGROUND Practice pattern variations are often attributed to physician decision-making with no accounting for patient preferences. OBJECTIVE To test whether a mass media television broadcast unrelated to health was associated with changes in the rate and characteristics of visits for acute emergency care. DESIGN Time-series analysis of emergency department visits for any reason. SUBJECT...

Broadcasting has been proved to be an efficient means of disseminating data in wireless communication environments (such as Satellite, mobile phone networks; other typical broadcast networks are Videotext systems). Recent works provide strong evidence that correlationbased broadcast can significantly improve the average service time of broadcast systems. Most of the research on data broadcastin...
