    Exploring deceptive behavior in intra-organizational activities of teleworkers in the IT sector in Sri Lanka
    (Springer Science and Business, 2025-07-04) Rajapakshe, W; Bangsajayah B.S.A
    This study aims to explore and validate a conceptual framework based on socio-technical systems and information manipulation theories to understand how deficiencies in IT infrastructure and interpersonal distrust lead to communication breakdowns and foster deceptive behavior. The research examines this phenomenon, which became particularly pronounced as companies shifted to remote work during the COVID-19 pandemic. The study employs moderated regression analysis (MRA) utilizing the PROCESS macro model 7 to assess hypotheses concerning the mediated moderation effect of deception. Data was collected from a judgmental sample comprising 200 remote IT workers to probe their motivations for deceptive practices within virtual work environments. Research findings demonstrate that the moderated mediation index (the interpersonal trust index) is −.1894. Moderated mediation is statistically significant, not including zero, as indicated by the 95% confidence interval (−.2380 to −.1385). Interpersonal trust moderates the indirect effect of IT infrastructure on communication deception. These findings imply that teleworkers can effectively communicate information if companies provide the infrastructure. Interpersonal trust can increase communication even in inappropriate household environments. Employers should prioritize managing trust and maximizing human capital to create a win–win situation for the company and teleworkers. This study sheds light on the role of interpersonal trust in shaping the relationship between communication and deception, filling a gap in the empirical literature on virtual work environments in the post-pandemic landscape. It provides novel insights by demonstrating how organizational trust moderates communication dynamics and mediates the influence of both deceit and IT infrastructure provision.

    Group Formation and Communication of Multitasking Multi-Robots for Smart City Cleaning Process
    (IEEE, 2022-12-09) Dahanaka, D.M.S.J; Wijesooriya, A.I.E; Wickramasinghage, D.S.S; Bhaggya, G.V.C; Harshanath, S.M.B; Rajapaksha, U. U. S
    In this research paper, we focus on how multitasking robots team up to clean a city. In particular, we consider how they build their team, how they position themselves in their positions, how they work with teams, how they face obstacles along the way, and how to move groups out of control in an emergency. We use a leader-follower strategy here, and we are also tasked with selecting a leader for each group. The leader finds the shortest route to avoid the obstacle by considering the obstacle details such as obstacle location, obstacle width, and destination. The leader decides the best way for the team to go. If the leader wants to change the group, it gives the message to the relevant member. In the event of meeting an obstacle, it changes its shape and moves. A Robot Operating System (ROS) framework was created to perform real-time experiments with ROS-capable mobile robotic TURTLEBOTs to evaluate this control strategy. Simulations performed on a mobile robot team demonstrate the effectiveness of the proposed approach.

    ROS Supported Heterogeneous Multiple Robots Registration and Communication with User Instructions
    (IEEE, 2022-02-23) Rajapaksha, S; Jayawardena, S; MacDonald, B. A
    Different types of heterogeneous multiple service robots are working in the same environment to help humans in many ways in a smart house. These service robots have different capabilities based on the different control and communication systems. The complexity of the programming of the robots is now reduced by using middleware like Robot Operating System (ROS). However, the communication and control of the heterogeneous service robots using very high-level instruction is still tricky because of differences in ROS topics. If a user has issued a high-level instruction to all multiple heterogeneous robots in the same environment, then all robots must complete the given task without considering the software differences in each robot. This research has developed a web-based interface where users can input high-level instruction to all multiple heterogeneous robots running in the same environment. We have used three levels of instructions. Level 01 moves robot forward for the given speed for some distance without obstacles. Level 02 is to move the robot to a specific location without obstacles. Level 03 is to navigate the robot to a goal with some obstacles in the environment. Initially, all robots need to register their software specifications and hardware specification Format (URDF) in the robot registration engine with the help of the ontology. Then all service robots act according to the instruction given by the interpreter. The proposed system was evaluated using a simulated environment with a gazebo using "Turtlebot" and "Tiago" robots. Time complexity analysis of all algorithms was completed using the Big O notation.

    Multi-Cloud Container Communication Using Software Defined Networks
    (IEEE, 2019-12-05) Najath, M; M.S Fayas Akram, M. F. S; Ahamed, I. A; Rankothge, W
    Over the last decade, cloud computing has changed the IT world, mainly in the ways of storing, accessing and securing the users' data. However, there is no single cloud management platform in the market that can be used to manage different clouds (ex: AWS and AZURE), together with container communication between the clouds, to cater different cloud user requirements. We have proposed a platform for cloud service providers that automates the multi-cloud management related services with following modules: (1) communication, (2) resource allocation and (3) log view. Our results show that, using our proposed modules, the multi-cloud management related services can be automated efficiently and reliably.
