In the era of digitalization, people store their data digitally on local or remote storage. To prevent data loss due to disk failures, data fault tolerance mechanisms have been widely deployed to provide different levels of reliability. However, applying data fault tolerance mechanisms incurs extra cost on storage space and energy consumption. Therefore, data with different importance should be stored...
Through replication, Redis has played a primary role in the improvement in the reliability and performance of NoSQL-style database systems in addition to applying added characteristics such as database flexibility and scalability. However, while Redis enables the seamless replication of datasets, Replication becomes difficult when applied to high-volume databases. As a result, effective database scaling...
This paper evaluates a mechanism for applying machine learning (ML) to identify over-constrained IaaS virtual machines (VMs). Herein, over-constrained VMs are defined as those who are not given sufficient system resources to meet their workload specific objective functions. To validate our approach, a variety of workload-specific benchmarks inspired by common Infrastructure-as-a-Service (IaaS) cloud...
Hybrid cloud is an emerging cloud deployment model that integrates public and private clouds. The key technology in building a hybrid cloud environment is the method of integration of different types of clouds. However, research on cloud integration technology and related solutions is lacking. Therefore, the adoption of hybrid cloud environment has been delayed. In this paper, we propose a hybrid...
Nowadays, systems for various smart city industries such as city power plants, public transportation and integrated modular avionics are becoming increasingly complicated, with most of components being embedded and geologically distributed. In order to ensure the availability of target systems, prognostic and health management develops as an important system to assess the current health state and...
In embedded avionic system, time and space partitioning is introduced to achieve stable and secure performance. Tasks must meet the certain time constraints when executed. Proper scheduling scheme is needed to ensure that the hardware is adequately used and all time and function requirements are met. However, existing partition aware scheduling works for no more than 2 partitions only. In this paper,...
With the increase in the instances of damage caused by counterfeits of electronic components, a Physical Unclonable Function (PUF) has attracted attention as a technique to prevent counterfeiting. PUF uses arbitrary dispersion as specific identification, which is generated during semiconductor manufacturing. Even if all LSI circuit patterns are copied, PUF can discriminate the LSI circuit from counterfeits...
The digitization of the physical world and the daily life becomes more and more interesting for research and industry. The key technologies for the digitization can be found in the fields of Internet of Things (IoT) and Cloud Computing. One of the different settings for IoT containing a high potential to create value for users and industry is Smart Office. The existing applications comprise a large...
In recent years, small and medium organizations have migrated to the cloud. Cloud computing provides information technology (IT) services, which can be found with Internet access from any place at any time. One can get services through application software like web browsers and mobile applications. Virtualization indicates the main concept to manage an IT infrastructure and data centers in the cloud...
Cloud Computing has emerged as a popular technology that support computing on demand services by allowing users to follow the pay-per-use-on-demand model. Minimizing energy consumption in cloud systems has many benefits that enable green computing. Energy aware task scheduling in cloud to the users by service cloud providers has non negligible influences on optimal resources utilization and thereby...
As one of the most common and aggressive means, denial-of-service (DoS) attacks cause serious impact on computing systems and networks. This paper presents a system for detecting denial of service (DoS) attacks in a network using a combination of the dendritic cell algorithm (DCA) and the negative selection algorithm (NSA). The proposed system classifies incoming network traffic into either of two...
Internet-based online cloud services provide enormous volumes of storage space, tailor made computing resources and eradicates the obligation of native machines for data maintenance as well. Cloud storage service providers claim to offer the ability of secure and elastic data-storage services that can adapt to various storage necessities. Most of the security tools have a finite rate of failure, and...
