Exploiting Regional Differences: A Spatially Adaptive Random Access [PDF]

open access: yes, 2015
In this paper, we discuss the potential for improvement of the simple random access scheme by utilizing local information such as the received signal-to-interference-plus-noise-ratio (SINR).

Low Latency Random Access for Small Cell Toward Future Cellular Networks

open access: yesIEEE Access, 2019
In future cellular networks, performance target includes not only increasing data rate, but also reducing latency. The current LTE-Advanced systems require four message exchanges in the random access and uplink transmission procedure, thus inducing high ...

Multistate spin-transfer-torque random access memory [PDF]

open access: yes, 2016
Spin-transfer-torque random access memory (STT-RAM) is an emerging non-volatile memory technology that stores information as the relative alignment of two ferromagnets in a magnetic tunnel junction stack.

Entanglement assisted random access codes

open access: yes, 2010
An (n,m,p) Random Access Code (RAC) allows to encode n bits in an m bit message, in such a way that a receiver of the message can guess any of the original $n$ bits with probability p, greater than 1/2.

Random Access Using Deep Reinforcement Learning in Dense Mobile Networks

open access: yesSensors, 2021
5G and Beyond 5G mobile networks use several high-frequency spectrum bands such as the millimeter-wave (mmWave) bands to alleviate the problem of bandwidth scarcity. However high-frequency bands do not cover larger distances.

Asynchronous Pattern-Designed Channel Access Protocol in Underwater Acoustic Wireless Sensor Networks

open access: yesJournal of Marine Science and Engineering, 2023
Due to the significant propagation delay in underwater sensor networks, conflict retransmission in channel access protocols comes at a high cost. This poses a challenge in scenarios where multiple sensor nodes generate data frames with strong temporal ...
