An adaptive trust based service quality monitoring mechanism for cloud computing

Cloud computing is the newest paradigm in distributed computing that delivers computing resources over the Internet as services. Due to the attractiveness of cloud computing, the market is currently flooded with many service providers. This has necessitated the customers to identify the right one meeting their requirements in terms of service quality. The existing monitoring of service quality has been limited only to quantification in cloud computing. On the other hand, the continuous improvement and distribution of service quality scores have been implemented in other distributed computing paradigms but not specifically for cloud computing. This research investigates the methods and proposes mechanisms for quantifying and ranking the service quality of service providers. The solution proposed in this thesis consists of three mechanisms, namely service quality modeling mechanism, adaptive trust computing mechanism and trust distribution mechanism for cloud computing. The Design Research Methodology (DRM) has been modified by adding phases, means and methods, and probable outcomes. This modified DRM is used throughout this study. The mechanisms were developed and tested gradually until the expected outcome has been achieved. A comprehensive set of experiments were carried out in a simulated environment to validate their effectiveness. The evaluation has been carried out by comparing their performance against the combined trust model and QoS trust model for cloud computing along with the adapted fuzzy theory based trust computing mechanism and super-agent based trust distribution mechanism, which were developed for other distributed systems. The results show that the mechanisms are faster and more stable than the existing solutions in terms of reaching the final trust scores on all three parameters tested. The results presented in this thesis are significant in terms of making cloud computing acceptable to users in verifying the performance of the service providers before making the selection

A framework for IoT-enabled environment aware traffic management

Vehicular traffic has increased across all over the world especially in urban areas due to many reasons including the reduction in the cost of vehicles, degradation of the quality of public transport services and increased wealth of people. The traffic congestion created by these vehicles causes many problems. Increased environment pollution is one of the most serious negative effects of traffic congestion. Noxious gases and fine particles emitted by vehicles affect people in different ways depending on their age and present health conditions. Professionals and policy makers have devised schemes for better managing traffic in congested areas. These schemes suffer from many shortcomings including the inability to adapt to dynamic changes of traffic patterns. With the development of technology, new applications like Google maps help drivers to select less congested routes. But, the identification of the best route takes only the present traffic condition on different road segments presently. In this paper the authors propose a system that helps drivers select routes based on the present and expected environment pollution levels at critical points in a given area

Parallel computing techniques for interferometric sonar based imaging

This research work presents a novel method for the determination of phase delay, which is based on Residue Number Systems (RNS) arithmetic. It has been shown that, by incorporating RNS, a high degree of parallelism could be introduced within the unwrapping process. This provides for the realization of a high-speed architecture to compute the required phase delay.Master of Applied Scienc

Smart Shopping System with RFID Technology Based on Internet of Things

The Internet of Things (IoT) incorporates most extensive number of innovations and imagines a mixture of things or questions around us that, through one of a kind tending to plans and standard correspondence conventions, consume the ability to connect through one another's also collaborate by their neighbors in the direction of attain regular purposes. The misuse of such a standard has been broadly explored in Internet-related investigates. As a result, a few plans have been suggested that utilization informal organizations to hunt Internet assets, to course activity, or to choose powerful strategies for substance dissemination. The essential understood this knowledge remains persistent locality everywhere us as a diverse carrier of things or articles – i.e. Radio-Frequency identification (RFID) sensors, labels, cellular telephones, actuators, and more – that finished novel inclining to ideas, consume the ability to subordinate through one another besides chip in through their neighbors to realize normal objectives of shopping situation in business sector. Web of Things (IoT) overpowered standard imperfection for structure code, which backing to shopping in business sector or undertaking gathering of most prominent concern and examinant.
