A STUDY OF AN ECO-FRIENDLY STREET LIGHTING SYSTEM FOR A SUSTAINABLE FUTURE
(researchgate.net, 2022-08) Neelawathura, R. W; Siriwardena, S. D; Sinnathamby, R. A; Ruwandika, S
The fundamental goal of this research is to create something that is long-lasting, environmentally friendly, and energyefficient for everyday consumers. As a result, the concept of an automatic green street lighting system was proposed, addressing the issue of needless road illumination and, in particular without energy wastage. Street lighting when it is not required is a waste of resources and electrical energy in general. Modern civilization has adopted the philosophy of "Going Green," which is emphasized at all times, particularly in the engineering field. Engineers come up with novel ways to save energy while improving the efficiency of their goods. One of these methods is to use a smart system, which has applications in numerous areas of society, such as at home, at work, and so on. Our main goal is to reduce energy while maintaining user-friendliness. Smart systems, created years ago, are still the foundation and are used to this day, improving as time goes on and striving for even greater development.

Automated Attendance Monitoring System Using IoT
(2019 1st International Conference on Advancements in Computing (ICAC), SLIIT, 2019-12-05) Kovelan, P.; Thisenthira, N.; Kartheeswaran, T.
Most of the process is automated to reduce human intervention and manual mistakes in this busy world. It will be easy if we can automate some complex, sensitive activities of day to day life. This paper discusses a smart attendance system that automatically monitors and manages the attendance of students in an educational institution. Further, this system makes automated analysis and prepares a detailed report weekly, monthly and annually. The whole system is developed with an Arduino microcontroller and RFID readers. Also, GSM and Wi-Fi communication modules are used to make convenient communication depend on the availability of the network. A microchip (microSD) is placed to store data in case of communication failure and those stored data will be uploaded bulk when the communication channel is restored. This system will reduce a lot of manual work of educators and education administrators of an education institution

Secure Communication Using Steganography in IoT Environment
(2020 2nd International Conference on Advancements in Computing (ICAC), SLIIT, 2020-11-10) Amjath, M.I.M.; Senthooran, V.
IoT is an emerging technology in modern world of communication. As the usage of IoT devices is increasing in day to day life, the secure data communication in IoT environment is the major challenge. Especially, small sized Single-Board Computers (SBCs) or Microcontrollers devices are widely used to transfer data with another in IoT. Due to the less processing power and storage capabilities, the data acquired from these devices must be transferred very securely in order to avoid some ethical issues. There are many cryptography approaches are applied to transfer data between IoT devices, but there are obvious chances to suspect encrypted messages by eavesdroppers. To add more secure data transfer, steganography mechanism is used to avoid the chances of suspicion as another layer of security. Based on the capabilities of IoT devices, low complexity images are used to hide the data with different hiding algorithms. In this research study, the secret data is encoded through QR code and embedded in low complexity cover images by applying image to image hiding fashion. The encoded image is sent to the receiving device via the network. The receiving device extracts the QR code from image using secret key then decoded the original data. The performance measure of the system is evaluated by the image quality parameters mainly Peak Signal to Noise Ratio (PSNR), Normalized Coefficient (NC) and Security with maintaining the quality of contemporary IoT system. Thus, the proposed method hides the precious information within an image using the properties of QR code and sending it without any suspicion to attacker and competes with the existing methods in terms of providing more secure communication between Microcontroller devices in IoT environment.
