    Btdm: a qos-based trust distribution mechanism for cloud computing
    (Faculty of Information Technology, University of Moratuwa., 2020-12) Firdhous, MFM; Budiarto, R; Karunananda, AS; Talagala, PD
    Cloud computing makes the delivery of computing resources over the Internet as services. As there are many providers in the market, it is necessary to monitor their performance. Several mechanisms for monitoring service quality of providers have been reported in the literature. But, it is not possible to monitor the entire cloud system by a single monitor. Hence, there is a need for a mechanism to share the performance metrics across a large geographical area. In this paper, the authors propose a mechanism called Bayesian Trust Distribution Mechanism (BTDM) for sharing the performance metrics as trust scores across an extended geographical area. The proposed BTDM also checks the reliability of the received scores based on their previous experience and adjusts them based on the reliability of sender. BTDM was tested using simulations and the results show that it performs better than the other mechanisms reported in the literature.

    Building social resilience during disasters: an investigation into the role of online social media networks
    (Faculty of Information Technology, University of Moratuwa., 2020-12) Firdhous, MFM; Karunananda, AS; Talagala, PD
    Within the last ten years, the world witnessed four serious epidemics. COVID-19 has been the most serious of these ones in terms of the number of people affected and the lives lost. In order to contain the spread of the disease many countries including Sri Lanka enforced 24 hour curfews. The social isolation created by lockdowns creates many problems in people including anxiety and depression. Many studies have been carried out on effect of lockdowns on mental well being of people. But, so far nobody has studied whether online social me can help people overcome the negative effects of lockdowns. This research was carried out to fill this gap. An online survey was carried out to understand how people used social media during the continuous curfew enforced by the Sri Lankan government. The research found that the average time spent using social media has increased compared to normal days. Also, majority of the users agreed that the social media helped them overcome the boredom created by the lockdown. This fact was confirmed using statistical tests in this study.

    Iot-enhanced smart laser fence for reducing human elephant conflicts
    (Faculty of Information Technology, University of Moratuwa., 2020-12) Firdhous, MFM; Karunananda, AS; Talagala, PD
    Human animal conflict is a serious problem in several countries in the Asian and African continents. The human animal conflict commonly results in the damage to properties and loss of human/animal life and limbs. The conflict between elephants and humans is considered to be one of the most serious conflicts due to the nature of losses incurred. The most commonly used deterrent used to keep the animals away from human settlements is the electric fence. Though, electric fences could act as a barrier for elephants to enter into villages, with time elephants learn to break them and enter villages. This paper presents the design of a smart laser fence that can be used for detecting elephants as well as chasing them back to the jungle with the help of other associated systems. The tests carried out on the system show that the concept is working and can be deployed in the field after an extensive field test.
