“…Furthermore, light-weight TCP implementations such as micro-IP TCP (μIP) [20] and light-weight IP TCP (lwIP), provide a much smaller stack size with minimal memory usage making them suitable for IoT scenarios. The light-weight implementations can be made even more suitable for IoT scenarios by the use of radio duty cycle (RDC) mechanisms [21] at the Medium Access Control layer to further minimise the power usage [15,22]. To date, although multiple aspects of light-weight TCP implementations have been investigated for IoT scenarios, congestion control remains a challenge that is rarely investigated for constrained IoT networks.…”

The Internet of Things (IoT) is a growing technology that remotely connects multiple devices (ranging across many fields and applications) over the Internet. The scalability of an IoT network mandates a reliable transport infrastructure. Traditional transport control protocol (TCP) control protocol is unsuitable for such domain, mainly due to energy and power consumption reasons. A lighter version of TCP, light weight IP (lwIP) provides a promising solution for current and projected future scalable IoT infrastructures. However, the original lwIP is just a simple mapping of the protocol, without insight into the IoT specific requirements. This paper examines the lwIP congestion control mechanism and addresses its shortcomings. In particular, a detailed examination is devoted to the various metrics such as retransmission time‐outs and its back‐off epochs, the congestion window behaviour and progress in the absence (and presence) of congestion. In particular, we propose a set of novel algorithms to address both the IoT constraints nature (light‐weight) as well as keeping up with scalability in IoT network size and performance. A detailed simulation study has been conducted to endorse the viability of our proposed set of algorithms for next‐generation IoT networks.
