Learning-Based and Data-Driven TCP Design for Memory-Constrained IoT

Abstract

Advances in wireless technology have resulted in pervasive deployment of devices of a high variability in form factors, memory and computational ability. The need for maintaining continuous connections that deliver data with high reliability necessitate re-thinking of conventional design of the transport layer protocol. This paper investigates the use of Q-learning in TCP cwnd adaptation during the congestion avoidance state, wherein the classical alternation of the window is replaced, thereby allowing the protocol to immediately respond to previously seen network conditions. Furthermore, it demonstrates how memory plays a critical role in building the exploration space, and proposes ways to reduce this overhead through function approximation. The superior performance of the learning-based approach over TCP New Reno is demonstrated through a comprehensive simulation study, revealing 33.8% and 12.1% improvement in throughput and delay, respectively, for the evaluated topologies. We also show how function approximation can be used to dramatically reduce the memory requirements of a learning-based protocol while maintaining the same throughput and delay.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some RL-based approaches for updating CWND are designed for resource-constrained networks including WANETs and IoT, while others address wider network architectures such as satellite, cellular, and data center networks.

    “Some of these approaches are particularly designed for resourceconstrained networks, including WANETs [29,219,379,380] and IoT [271], while others address a wider range of network architectures [30,122,477], such as satellite, cellular, and data center networks.”
  • Basic simulations in ns-3 reveal that FK-TCPLearning improves the throughput and delay of TCP-NewReno, while being marginally inferior to TCPLearning.

    “Furthermore, basic simulations in ns-3 reveal that FK-TCPLearning improves the throughput and delay of TCP-NewReno, while being marginally inferior to TCPLearning.”
  • FK-TCPLearning with a set of 100 prototypes needs only 1.2% (2.4KB) of the memory used by pure Q-learning TCPLearning (200KB) for storing 50,000 state-action pairs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
