IAMBEE : a web-service for the identification of adaptive pathways from parallel evolved clonal populations [PDF]

open access: yes, 2019
IAMBEE is a web server designed for the Identification of Adaptive Mutations in Bacterial Evolution Experiments (IAMBEE). Input data consist of genotype information obtained from independently evolved clonal populations or strains that show the same ...

Adaptive Demodulation in Differentially Coherent Phase Systems: Design and Performance Analysis

open access: yes, 2010
Adaptive Demodulation (ADM) is a newly proposed rate-adaptive system which operates without requiring Channel State Information (CSI) at the transmitter (unlike adaptive modulation) by using adaptive decision region boundaries at the receiver and ...

Analysis and Enhancement of the LoRaWAN Adaptive Data Rate Scheme

open access: yesIEEE Internet of Things Journal, 2020
The adaptive data rate (ADR) algorithm is a key component of the LoRaWAN protocol which controls the performance of a LoRaWAN Network. This modifies the data rate parameter of a device based on the current wireless conditions. In this article, we present

Fair Adaptive Data Rate Allocation and Power Control in LoRaWAN [PDF]

open access: yesIEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks, 2018
In this paper, we present results of a study of the data rate fairness among nodes within a LoRaWAN cell. Since LoRa/LoRaWAN supports various data rates, we firstly derive the fairest ratios of deploying each data rate within a cell for a fair collision ...
