Contention resolution with collision cost [PDF]

Contention resolution coordinates access to a shared communication channel divided into synchronized slots. For any fixed slot, a packet can be sent, leading to three outcomes: empty (no packet sent), successful (one packet sent), or collision (multiple ...

Peace Journalism through the Lense of Conflict Theory: Analysis and Practice [PDF]

Conflict & Communication Online, 2006
Peace Journalism is a bold attempt to redefine and reconstruct the role of journalists who cover conflicts. As a new arena of knowledge, Peace Journalism draws upon several theories and disciplines to enrich its validity and applicability. A major source

On elastic traffic via contention resolution diversity slotted aloha satellite access

, 2014
Summary This paper presents a performance study relative to the coupling of the Transmission Control Protocol (TCP) with the Contention Resolution Diversity slotted aloha (CRDSA) protocol, in the case of greedy TCP connections (also called elephants) on ...

Contention Resolution with Heterogeneous Job Sizes

, 2008
. We study the problem of contention resolution for differentsized jobs on a simple channel. When a job makes a run attempt, it learns only whether the attempt succeeded or failed.

Improvement of WLAN contention resolution by loss differentiation

, 2008
– In a realistic WLAN environment, frame losses may be caused by collisions or channel noise. The existence of noise-induced losses reduces the effectiveness of the standard WLAN backoff algorithm for contention resolution, which assumes that all losses ...

Performance Evaluation of Separate Chaining for Concurrent Hash Maps

Mathematics
Hash maps are a widely used and efficient data structure for storing and accessing data organized as key-value pairs. Multithreading with hash maps refers to the ability to concurrently execute multiple lookup, insert, and delete operations, such that ...

Fixed-Wavelength Conversion for Contention Resolution in Optical Packet Switches

, 2004
Wavelength conversion (WC) is highly useful for contention resolution ill optical packet switches (OPS). However, the immature technology and the high cost of full-range tunable-wavelength converters (FTWCs) remain big challenges. We propose a new scheme

A novel Hybrid Polling Algorithm for Packets Contention Resolution in optical switching based Data Center Network

, 2019
We demonstrate a novel hybrid polling algorithm for optical packets contentions resolution (HPACS) for OPSquare data-centre network based on fast optical switches. Results show that the HPACS reduces 46.47% latency, and 18.73% packet-loss at traffic load
