Abstract

Pervasive applications over large-scale, distributed embedded devices and the Internet of Things (IoT) demand precise coordination with the network; for example, several such applications, like collaborative video streaming and live analysis, augmented reality, etc., need continuous monitoring of network throughput and adapt the application behavior accordingly. Although the idea of network throughput prediction is not new and quite dated, in this paper, we show that the existing approaches fail to correctly infer the throughput when the network operator or the device change, and thus, not generic enough for Internet-scale applications. We propose FedPut, a novel approach that allows collaborative training across different client hardware by capturing throughput variations based on devices’ sensitivity towards the corresponding network configurations. Rigorous evaluations show that FedPut outperforms various standard baseline algorithms with more than 80% R2-score over different datasets. We also analyze the performance of FedPut over a network-aware streaming media application and demonstrate its efficacy for various application scenarios.

File Description

To run and test the throughput prediction algorithms for different thoughput datasets with standard centralized learning run central_learning.py. The helper functions for preparing the datasets and the fedput implementation is provided in fedput.py. To test fedput under Tensorflow-Federated setup use tff_eval.py.
