Resilient Consensus Through Event-Based Communication

Resilient Consensus for Infinitely Many Processes

We provide results for implementing resilient consensus for a (countably) infinite collection of processes. – For a known number of faults, we prove the following equivalence result: For every t ≥ 1, there is a t-resilient consensus object for infinitely many processes if and only if there is a t-resilient consensus object for t + 1 processes. – For an unknown or infinite number of faults, we c...

On the Nonexistence of Resilient Consensus Protocols

In [3], Fischer, Lynch and Paterson proved that in asynchronous message passing systems there cannot exist a consensus protocol that tolerates even a single undetectable crash failure. Their proof of this fundamental result relies on operational details such as sending and receiving messages, etc. Chandy and Misra [1] have taken an axiomatic non-operational approach to the consensus problem. Th...

Optimization/simulation-based risk mitigation in resilient green communication networks

constructing gender identity through narratives based on hallidays metafunctions

هویت, شکل دادن و بازنمایی آن در گفتمان, توجه بسیاری از محققان این رشته را به خود جلب کرده است. تحقیق حاضر بر شکل دادن به هویت جنسیتی هشت تن از دانشجویان ایرانی مشغول به تحصیل در دوره کارشناسی ارشد از طریق بررسی روایات آنان از تجربیات شخصی, متمرکز شده است. تحلیل داده ها در این تحقیق مشتمل بر سه بخش است: بخش اول شامل کدگذاری موضوعی روایات است که بر اساس آن هویت جنسیتی شرکت کنندگان در تحقیق بر اسا...

Event-Based and Publish/Subscribe Communication

The communication models found in distributed systems can be classified according to the following two attributes: who initiated the communication and how the communication partner is addressed. The resulting four models are shown in Table 1. Provider-initiated communication is also often called push communication and consumerinitiated communication is also often called pull communication. abst...
