Working towards my doctoral, my research objectives are focused on enabling inexperienced personal (doctor, farmer, etc.) to prototype (both hardware and software) end-to-end IoT applications on heterogeneous IoT devices. The main research problem being interoperability issues that arises because of heterogeneous IoT device architecture, communication & network protocol specifically at layer-1. For this, we are developing a framework for interoperable IoT applications - development, deployment and maintenance - on heterogeneous embedded devices. The prototype of this framework is being developed in python and the underlying device firmware in C/C++. Throughout the development process I have extensively used various embedded systems boards (Arduino, MSP430, STM32 Nucleo, NXP-FRDM, RPi, etc) and sensors for testing the framework’s functionalities and IoT application use cases.
From hardware perspective, we proposed and validated a new modular architecture named R-Bus (Resource Bus) for embedded system design, that allow easy and rapid hardware prototyping of IoT applications and facilitate configuration of R-Bus interface based on available IoT resources (sensors, actuators, transceivers, human machine interface, etc.).
The results of my research are summarized in 5 publications in various reputed international conferences.

Before joining PhD, my doctoral advisor invited me to join her research group as a research engineer. This is a common practice in France to get acquainted with mutual research interest and working style before proposing a PhD contract.
I worked on the same topic as my PhD but mostly inclined towards framing the research problem and literature survey.
