Auction mechanisms for Virtualization in 5g cellular networks: Basics, trends, and open challenges
IEEE Communications Surveys and Tutorials, 2018Co-Authors: Ummy Habiba, Ekram HossainAbstract:Wireless network Virtualization (WNV) is considered as a reliable and effective solution to enhance the capacity and resource utilization in emerging 5G cellular wireless networks. WNV supports network sharing and multi-tenancy by allowing application or service providers with limited resources to lease network resources from mobile network operators. Several works in the literature surveyed various aspects of resource allocation and network slicing methods to Implement Virtualization in wireless networks. In this paper, we focus on economic aspects of WNV and study auction theory as a fundamental tool for designing business models for Virtualization of wireless networks, 5G cellular networks in particular. Starting with the concept of WNV in 5G cellular networks, we describe the basic principles and solution approaches in auction theory for heterogeneous and multi-commodity scenarios. Subsequently, we review the recent advances in WNV based on auction models. We conclude by outlining the open challenges and future research directions related to applications of auctions in WNV.

Identifying critical factors for corporate Implementing Virtualization technology
Computers in Human Behavior, 2012Co-Authors: Shing-han Li, Chung-chiang Hu, Wen-hui Lu, Yung-chen ChiuAbstract:Virtualization technology has attracted great attention with its advantages of multiple platform operation and resultant cost and power reduction. This study investigated the key factors for corporations to Implement Virtualization information environment from the viewpoint of IT staffs. Through purposeful sampling, 400 effective questionnaires were collected from IT personnel currently working in the Virtualization-related fields. From key factor analysis, seven influential factors were identified for corporations to Implement Virtualization. These seven factors include: (1) system quality, (2) information quality, (3) simplified management and maintenance, (4) integration of resources, (5) cost reduction, (6) ease of deployment, test and development, and (7) organizational consensus. Based on the obtained findings, suggestions for corporations and to IT system integrators were provided to the Implementation of Virtualization information environment. The scales developed in this study provide useful measures to study common factors of the Implementation of Virtualization information technology.

Distributed Replicated Block Device (DRDB) Implementation on cluster storage data migration
2015 International Conference on Data and Software Engineering (ICoDSE), 2015Co-Authors: Mardhani Riasetiawan, Ahmad Ashari, Irwan EndrayantoAbstract:Data Center systems are required to have high availability in order to meet the continuing needs of the user. If the server or application in which a failure or require maintenance, the virtual machine will be migrated to another server in the cluster are still available. The role of shared storage is very important here to keep a virtual machine that can continue the work and do not lose data on the destination server. This study seeks to Implement Virtualization at the server cluster system uses a virtual machine on Proxmox VE and Distributed Replicated Block Device (DRBD) as shared storage. Implementation is done by using two nodes, and made a comparison with two other nodes in the cluster system that does not use shared storage. Shared storage works by synchronizing and replication of virtual machine data that can then migrate online. The use of shared storage will affect virtual machine performance, especially on the speed of the disk during the process of sending and receiving data, and the availability of services. Measurement of downtime during the migration to test the success of the system. Testing the TCP connection is made to ensure the network throughput and connection test results compared to test disk performance.
