Abstract -
We intend to study the effect of auditor reputation, audit tenure and firm size on audit quality in manufacturing companies listed on the Indonesia Stock Exchange for the 2013-2017 periods. Logistic regression analysis is the appropriate regression model for this study that uses categorical independent variables (nominal or non-metric) and metric and non-metric dependent variables. Logistic regression analysis does not require assumption of normality for the independent variable data. From the analysis described in earlier sections, we have come to the conclusion that (1) auditor reputation affects audit quality; (2) audit tenure does not affect audit quality; and (3) firm size affects audit quality.

Abstract -
The movement pattern of users is of significant when evaluating the performance of different kinds of algorithms in wireless networking environments. In this paper, we propose an enhanced random waypoint mobility model (ERWP) to achieve a good trade off between reality and complexity. ERWP model uses two stochastic processes for speed change and waiting control, which make the movement of nodes smoother and more realistic. Simulation shows that the proposed ERWP model can provide a spatial distribution and movement behavior of a user in mobile region.

Abstract -
Recent developments in the computer industry owe a lot to innovations in networking infrastructure. Numerous protocols currently exist to exploit the Internets potential applicability. However, this situation causes unnecessary complexity in the configuration around units that compose networking systems in case of implementation of extended design. Network virtualization provides a solution to such complexities and forms a fundamental part of future network design. In particular, an overlay network in a physical infrastructure provides the freedom to maintain a customized network policy between distinct domains distributed across the Internet. This paper proposes an overlay network foundation comprising two systems. The first is multiple virtual servers that provide authenticated TCP services between an authorized client and a service provider. The second is a cloud-based system that provides cooperative applications on UDP between the supervisor on the client side and the service providers. The overlay network is operated by the virtual network interface card (vNIC) identifier, which results in simple embedding with no change in packet size. The systems architecture is based on an original design that constitutes a vNIC, a physical network interface card (pNIC), and a software. The vNIC creates the virtual host, while the relay system manages the software. Thus, pNIC provides an interface between the physical layer and the software layer. Finally, we conduct empirical testing of the proposed systems viability using real-life Internet-based research. The results show that our proposed system performs effectively and has good operability.
