    Aqua Safe: Blockchain Based Maritime Communication System using Ad hoc Network
    (IEEE, 2022-12-26) Lokuliyana, S; Wellalage, S; Warusavithana, L; Pathirana, M; Kodithuwakku, S
    The lack of a pre-existing infrastructure for facilitating long-range connectivity with the land makes maritime communications extremely difficult. Satellite connections, which are expensive, and use much power, are generally used to communicate on the high seas. For better connectivity between fisheries and land stations, different functional methods such as whether detection, boundary detection, data security, barrier detection, and data communication without interruption have been implemented in the system. Implementing a LoRa WAN system is to inform about emergencies in the deep sea and send the information indicated above. IoT node-based Ad hoc network is used to communicate with the land station without an internet connection. In case of emergency or when the fisheries need to send data and information to the land station in real-time, the fishing boat can interact with the land station through this proposed system. Blockchain technology is used in the system to ensure secure communication of information. In this scenario, the blockchain technology has enabled it to deploy distributed networks and perform secure peer-to-peer transmission and data integrity without a third party accessing the network.

    Smart Vehicle Communication System for Collision Avoidance
    (IEEE, 2022-01-10) Ranawaka, M. N; Liyanage, K. S; Wickramasinghe, S. P; Chandrasekara, L. H. P. S. D; Chandrasiri, S. S; Weerathunga, L. I. E. P
    The purpose of this research paper is to present a mobile-based solution, the 'iDrive' application for safe driving and driver assistance. The paper begins by defining the research problem, the rapid intensification of motor vehicle accidents, and the resulting number of deaths because of excessive speeding and other related factors. This paper also discusses previous related research work in this area, as well as its limitations. Then, we propose an Android-based application that monitors the vehicle via an On-Board Diagnostics (OBD-II) interface, allowing it to detect accident scenarios, as well as the appropriate speed for driving on the road based on their GPS location, and an automated communication system that shares detected collisions with nearby drivers. Furthermore, this paper discusses the research project’s verified results and the evidence to show that the research met its primary goal.

    Indoor Autonomous Multi-Robot Communication System
    (IEEE, 2021-12-09) Gunawardhana, K. D. W; Kularathana, D. G. D. P; Welagedara, W. H; Palihakkara, H. E; Abeygunawardhana, P. K. W; Wellalage, S
    Robotics, and automation systems are a hot issue right now. Controlling multiple robots at the same time has become very popular. On paper, we propose that a wireless robot-to-robot communication infrastructure be implemented to accomplish some specific tasks. The major goal of this proposed project is to showcase communication infrastructure, a dual manipulator system and a mobile charging dock robot have been designed to achieve this. Special topics and services were employed for communication infrastructure. It is more precise than current communication systems. Existing manipulation situations are limited to a single manipulator task; however, in this case, a dual manipulator task has been designed to work corporately. The charging docking stations are the only places where mobile robots may recharge. We presented a Mobile Charging Dock for recharging mobile robots in this project. This proposed project is introducing a secure communication strategy which uses a ROS topic filtering mechanism.
