Hidden Terminal-Aware Contention Resolution with an Optimal Distribution

, 2011
Achieving low-power operation in wireless sensor networks with high data load or bursty traffic is challenging. The hidden terminal problem is aggravated with increased amounts of data in which traditional backoff-based contention resolution mechanisms ...

A Queue-Aware Random Access Scheme for Massive Narrowband IoT: DTMC-Based Analytical Modeling and Performance Analysis

IEEE Access
Contention-based random access mechanisms play a central role in Narrowband Internet of Things (NB-IoT) systems designed to support massive machine-type communications.

Contention resolution with guaranteed constant expected delay [PDF]

We study contention resolution in multiple-access channels such as the Ethernet. Under a stochastic model of continuous packet generation from a set of n processors, we construct a protocol which guarantees constant expected delay for generation rates up

High-Throughput Random Access via Codes on Graphs [PDF]

, 2010
Recently, contention resolution diversity slotted ALOHA (CRDSA) has been introduced as a simple but effective improvement to slotted ALOHA. It relies on MAC burst repetitions and on interference cancellation to increase the normalized throughput of a ...

Contention resolution with bounded delay [PDF]

When many distributed processes contend for a single shared resource that can service at most one process per time slot, the key problem is devising a good distributed protocol for contention resolution.

Adaptive Transmission Control Considering Available Channels Difference Among Terminals in Satellite IoT Systems Using CRDSA/IRSA

IEEE Access
The use of Low Power Wide Area (LPWA) networks in the 920-MHz band, which are compatible with terrestrial network devices, is being explored for a satellite Internet-of-Things (IoT) system.

Advancing the Frontiers of Biophysical Research and Cellular Dynamics: Single-Molecule Tracking for Live Cells—A Deep Dive

Biophysica
This article addresses a current point of contention in the field of single-molecule/single-particle tracking, as well as the relevant literature, and supplements it with some published cell-based experiments to illustrate our conclusions and known ...

Deterministic non-adaptive contention resolution on a shared channel

, 2022
In a multiple access channel, autonomous stations are able to transmit and listen to a shared device. A fundamental problem, called \textit{contention resolution}, is to allow any station to successfully deliver its message by resolving the conflicts ...

The Conceptual Structure of Social Disputes

SAGE Open, 2014
We describe and illustrate a new method of graphically diagramming disputants’ points of view called cognitive-affective mapping . The products of this method—cognitive-affective maps (CAMs)—represent an individual’s concepts and beliefs about a ...
