Framework for Vetting and Identifying Emulated Android Mobile Apps
Get PDFMobile apps emulation is increasing becoming serious threat. Criminals target popular apps that are used to carry sensitive user information like financial usernames and passwords. Criminals can download and repackage these apps with malicious codes which will help in stealing user information or send annoying adverts to user that will benefit the criminals. This paper focuses on XDroid Moss, an enhanced vetting framework to detect the emulated apps
Workplace Factors That Shape IT Project Success
Get PDFInformation technology (IT) project success depends on having a project manager with effective decision-making, leadership, and project management skills. Project success also depends on completing the project in a given budget, time, and scope. However, there is a limited understanding of the lived experiences of IT managers and the following workplace factors: cultural, functional, and organizational differences. The purpose of this phenomenological study was to understand these lived experiences of 20 IT project managers or leaders at global workplaces based in the United States. The research questions were focused on the effect of these workplace factors on information technology project success. In accordance with nonrandom purposeful sampling strategies, a snowball technique was used to find more participants. An open-ended, e-mail questionnaire was created and sent to participants to collect data. The data were coded to discern themes or patterns. According to study results, team members should acquire a broader array of knowledge and experience; appreciate other cultures to create a more trusted working environment, leverage technical expertise and skills to foster team effectiveness, reduce project risks, gain and diversify skill sets; achieve more tasks in shorter time frame, and allow members to use creativity and talent. This study has implications for positive social change because organizations that understand the workplace factors may be able to improve project management strategies and cost benefits leading to higher efficiency, profitability, and productivity thus benefiting management, employees, and customers.
Ontology for Task and Quality Management in Crowdsourcing
Get PDFThis paper suggests an ontology for task and quality control mechanisms representation in crowdsourcing systems. The ontology is built to provide reasoning about tasks and quality control mechanisms to improve tasks and quality management in crowdsourcing. The ontology is formalized in OWL (Web Ontology Language) and implemented using Protégé. The developed ontology consists of 19 classes, 7 object properties, and 32 data properties. The development methodology of the ontology involves three phases including Specification (identifying scope, purpose and competency questions), Conceptualization (data dictionary, UML, and instance creation), and finally Implementation and Evaluation
Analysis and Design of "Dates Traceability System"
Get PDFFood chain traceability verifies the breadth and depth characteristics to meet the production process and to reach desired objectives such as insuring food safety and providing consumers with added confidence in the food authenticity. Information technology is an attractive solution that helps achieve the traceability objectives. This is especially true with the wide spread of the Web technologies. This paper is intended to enable any consumer for tracking dates products from its origin farm all the production stages to its final consumption. The functionalities of this system will include managing dates product data and their related actors, elaborating a way of coding dates product so that we can extract all traceability information using this code, helping/supporting finding anomalies (if any) in the chain of production and improving the dates quality. At any stage of the chain a product can be traced-back and offering services to health and government organizations to get better vision of the date\u27s product history.
Success Factors for Building and Managing High Performance Agile Software Development Teams
Get PDFInformation technology (IT) project success depends on having a project manager with effective decision-making, leadership, and project management (PM) skills. Project success also depends on completing the project in a given budget, time, and scope. However, there is a limited understanding of the Agile Leadership Effectiveness in Leading High Performance Team. Agile Software Development Team (ASDT) success factors such as organizational, people, process, project management, technical, trust, and so forth. The purpose of this paper is to present and synthesize the success factors generally accepted as critical in building and managing high performance ASDTs. These success factors consisted of ASDT (e.g., structure, member’ competencies, commitment and trust, communications, goals, and collaboration), leading ASDTs (e.g., leadership styles), workplace factors (e.g., cultural, functional and organizational differences), technologies (e.g., development tools), and organizational, people, process, and technical factors. Organizational leaders and practitioners from various industries who are building or managing ASDTs could be of benefits with the researcher’s study outcomes by implementing or developing strategies or processes that could improve ASDT performance for long term sustainable development. High performance ASDT outcomes include improve team overall performance, time to the market, project success rate, and a better safer and healthier organizations or society
Comparative Analysis of Two Prominent Routing Protocols in IPv6 Network: OSPFv3 & EIGRPv6
Get PDFDue to the huge demand of Internet, computer network has been transited from IPv4 to IPv6 environment. New routing protocols are also needed in IPv6 network. Among them two are very prominent: IETF’s OSPF and Cisco’s EIGRP. In IPv6 network, they are known as OSPFv3 and EIGRPv6 respectively. Though several researchers have worked in these area, but this paper have analyzed the comparisons between these two routing protocols more intensively. In this paper, packet loss, routing convergence speed and end to end delay have been considered as the parameters of the comparisons. The comparisons have been evaluated in Cisco’s simulation environment; Packet Tracer.
An Adaptive Framework For Bandwidth Allocation In Cloud Networks
Get PDFThe increasing user demands for services in Virtual Machines and Cloud computing has made the resource allocation an impossible task to be manually performed by human operators. Software Defined Networks (SDNs) and Virtual Networks have been increasingly getting attention as a way for managing these configurations due to the abstraction of the controlling part of the network and its decoupling from the forwarding layer. In this partial paper, we summarize the paradigm of SDNs and Virtual Networks and survey the state of-the-art of dynamic resource allocation in the field of Virtual Machines and Cloud computing using SDNs and Virtual Networks
3D Internet
Get PDFInternet, today has become an integral part of our lives. The World Wide Web which initially was a small and non-interactive data storage service is now huge and priceless. Present activities being partially or completely linked with the virtual world can be optimized to a higher level. Every activity associated with our daily life is mapped and related to some entity in the digital world. The world has seen vast advancements in Internet and in 3D stereoscopic displays. Time has come merge the two to deliver a new level of experience to the users. 3D Internet is an idea which is yet to be implemented and requires browsers having the property of depth perception and artificial intelligence. If this property is incorporated then the idea of Internet of things can become a reality which is also discussed in this paper. In this paper we have discussed the features, possible setup methods, applications, and advantages and obstacles faced in the implementation of 3D Internet. Through this paper we intend to provide a clear idea about 3D Internet and the possible benefits associated which clearly are worth the amount of financial investment required for it\u27s implementation
Performance Analysis of Three Transition Mechanisms between IPv6 Network and IPv4 Network: Dual Stack, Tunneling and Translation
Get PDFDue to the increasing demand of the Internet, we are facing a great problem of the depletion of our existing IPv4 (Internet Protocol version 4) network. To solve the situation, we have to use IP version 6 in coming years. But the IPv4 network will not be opt out, but also coexist with IPv6 network. For the transition from IPv4 to IPv6 and vice versa, there are three prominent transition mechanisms are used. They are Dual Stack, Tunneling and Translation. In this paper, the performances of these three mechanisms have been analyzed. IPv6 header format, its security and the routing also have been focused.
