Abstract

RCOAP: A Rate Control Scheme for Reliable Bursty Data Transfer in IoT Networks

Highlights

Internet of Things (IoT) networks are becoming increasingly significant in different types of applications, such as healthcare, agriculture, environment monitoring, and automation
The key idea of this paper is to enable in-flight packets for reliable bursty data transfer by adding some functionalities to the basic Constrained Application Protocol (CoAP) on top of User Datagram Protocol (UDP)
We found that the packet loss occurred at the load of 25% (IPI = 700 ms) in the basic CoAP, CoCoA, and CoCoA+

Summary

INTRODUCTION

Internet of Things (IoT) networks are becoming increasingly significant in different types of applications, such as healthcare, agriculture, environment monitoring, and automation. Many IoT applications rely on the occasional transmission of small payloads from IoT devices and must transfer large blocks of collected data to the server, resulting in an enormous amount of traffic in the network [1], [2]. CoCoA attempts to remedy the basic congestion control of CoAP by exploiting continuous measurements of the dynamic round-trip times (RTT) to limit the frequency of retransmissions. In [12], the authors suggested a congestion control algorithm for CoAP based on the TCP BBR (bottleneck bandwidth round-trip propagation time) protocol. In contrast to most current schemes, which have focused on loss-based approaches by adjusting RTO values for controlling the retransmission, this study considers an alternative approach using a rate-based mechanism. We propose a new rate control scheme, called RCOAP, for reliable bursty data transfer.
