The use of mobile instant messaging platforms has increased in recent years political communication given the private nature this form communication, a trend which during COVID-19 pandemic. aim research is to know Telegram usage done by main parties within election campaign. For purpose, Catalan 14th February 2021 are studied with quantitative content analysis on sample composed 600 messages pu...

In this paper, we study the performance of IEEE 802.11 broadcast scheme in multihop wireless networks using an analytical model. Previous works have evaluated the performance of IEEE 802.11 protocol assuming unicast communication, but there has not been an analysis considering broadcast communication. Analyzing performance of broadcast communication is important because multicast communication ...

Byzantine broadcast is a distributed primitive that allows a specific party (called “sender”) to consistently distribute a value v among n parties in the presence of potential misbehavior of up to t of the parties. Broadcast requires that correct parties always agree on the same value and if the sender is correct, then the agreed value is v. Broadcast without a setup (i.e., from scratch) is ach...

Capacity Region for a More General Class of Broadcast Channels Ghosheh Abed Hodtani Department of Electrical Engineering, Ferdowsi University of Mashhad, Mashhad, Iran [email protected] AbstractWe can categorize the broadcast channels with known capacity into two groups: One group consists of broadcast channels where the receivers have different capabilities (degraded, less noisy and more capab...

A d-broadcast primitive is a communication primitive that allows a sender to send a value from a domain of size d to a set of parties. A broadcast protocol emulates the d-broadcast primitive using only point-to-point channels, even if some of the parties cheat, in the sense that all correct recipients agree on the same value v (consistency), and if the sender is correct, then v is the value sen...

A wireless sensor network (WSN) is emerging as an innovative method for gathering information that will significantly improve the reliability and efficiency of infrastructure systems. Broadcast is a common method to disseminate information in WSNs. A variety of counter-based broadcast schemes have been proposed to mitigate the broadcast-storm problems, using the count threshold value and a rand...
