Adaptive Rate Subscriber Loop Data Transmission using Ethernet Interfaces
Journal of Circuits, Systems and Computers, 1997The increasing demand for Internet and World Wide Web access from the home has stimulated research into finding methods of providing access at rates greater than the 33.6 kb/s offered by current computer modems. Most copper telephone pairs have bandwidth capacities much greater than the 3.4 kHz voice-band. Using this excess bandwidth it is possible to

Self-adaptive sampling rate data acquisition in JET’s correlation reflectometer
Review of Scientific Instruments, 2008Data acquisition systems with self-adaptive sampling rate capabilities have been proposed as a solution to reduce the shear amount of data collected in every discharge of present fusion devices. This paper discusses the design of such a system for its use in the KG8B correlation reflectometer at JET.

AdaptaBLE: Data Rate and Transmission Power Adaptation for Bluetooth Low Energy
2019 IEEE Global Communications Conference (GLOBECOM), 2019The use of Bluetooth Low Energy (BLE) has been steadily increased since Bluetooth Special Interest Group (SIG) standardized BLE in 2010, and BLE performance has been improved owing to various studies. Bluetooth specification 4.2 defined only one data rate, i.e., 1 Mb/s.

Adaptive rate control over mobile data networks with heuristic rate compensations
2016 IEEE/ACM 24th International Symposium on Quality of Service (IWQoS), 2016Mobile data networks exhibit highly variable data rates and stochastic non-congestion-related packet loss. These challenges result in key performance bottlenecks in current Transmission Control Protocol (TCP) implementations: bandwidth inefficiency and large end-to-end delay.

Adaptive data rate using ARQ and nonuniform constellations
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002We introduce an automatic repeat request (ARQ) scheme that uses nonuniform signal constellations in order to adapt the data rate to the received signal-to-noise ratio (SNR) in a fading channel without using channel state feedback or incremental redundancy.

Performance comparison of different data rate adaptation mechanisms
33rd European Conference and Exhibition on Optical Communication - ECOC 2007, 2007Different data rate adaptation mechanism and their influence on network and traffic characteristics are visualized in radar plots in order to provide a fast and fair comparison of multiple parameters at the same time. Introduction In today’s transport links in core and metro area networks are often underutilized and transport capacity is wasted by the ...

Adaptive Data Rate for Multiple Gateways LoRaWAN Networks
2020 16th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2020We propose to optimize the LoRaWAN Adaptive Data Rate algorithm in case an inter-packet error correction scheme is available. We adjust its parameters based on the analysis of the LoRa channel with multiple reception gateways, supported by real-world traffic traces.

A DATA-RATE LIMITED VIEW OF ADAPTIVE CONTROL
IFAC Proceedings Volumes, 2006This paper addresses the problem of adaptively controlling a plant with unknown parameters using communication-limited feedback. Assuming known dynamics, expressions have recently been obtained for the minimum average feedback data rate required for asymptotic stabilisability.

Empirical Analysis of LoRaWAN-based Adaptive Data Rate Algorithms
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021Long Range Wide Area Networking (LoRaWAN) has established itself as one of the leading Media Access Control (MAC) layer protocols in the realm of Low Power Wide Area Networks (LPWAN). Although the technology itself is quite mature, the resource allocation mechanism, the Adaptive Data Rate (ADR) algorithm it uses is still quite new, unspecified and its ...

Multiplatform multisensor fusion with adaptive-rate data communication
IEEE Transactions on Aerospace and Electronic Systems, 1997An algorithm for multiplatform multisensor fusion with adaptive-rate data communication is presented. In this new communication/fusion scheme, data are compressed before communication, and decompressed and fused after communication. The amount of information to be compressed, as well as the data communication rate, depends on target kinematics.
