A CONTROL MECHANISM FOR RELIABLE BURST DATA TRANSFER IN IoT NETWORKS

Abstract

IoT networks are widely used in various
areas, such as industry, healthcare, agriculture, and the
environment. Many applications require to transfer a
large amount of data collected by IoT devices to a central
server. Without an appropriate control mechanism, the
network is prone to congestion. The Constrained
Application Protocol (CoAP) has been proposed for data
transmission in IoT networks. This paper analyzes the
shortcomings of CoAP and indicates that CoAP does not
have rate control and no support for burst data transfer.
To extend CoAP, we develop an analytical model for
reliable burst data transfer with CoAP using rate control.
Based on this model, we propose a new rate control
mechanism that allows reliable burst data transfer with
high throughput, low delay, and improved congestion
control of CoAP in IoT networks.
