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 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 (RTOs) 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.

The evolution of technology has made increasingly advantageous the introduction of Unmanned Aerial Systems (UASs) in various applications, especially by exploiting their ability for autonomous flight. This paper presents an innovative approach to simulating UAS maneuvers that integrates a Computational Fluid Dynamics (CFD) model and a closed-loop control algorithm for both position and attitude dynamics. We chose the Proportional-Integrative-Derivative (PID) controller for this preliminary research activity because of its simple implementation and widespread employment in commercial autopilot systems. The numerical simulation of the UAS aerodynamics allows for performing an accurate analysis in critical situations. These include, for example, ground effect or wind gusts scenarios, which require an enhanced propulsive model to capture the interaction between vehicle dynamics, aerodynamics, and environmental conditions. The coupled CFD/PID framework can be a virtual testing environment for UAS platforms. Here we report on its validation. The paper compares such an innovative in-the-loop CFD approach and a classical simplified propulsive model that adopts constant thrust and torque coefficients.
