In these days, wireless AP's signal is all around us. Multiple APs are set up at a big area, enterprise, university, movie theater, etc. and small area, such as a private house. So wireless APs are not special to us. However, the APs with several tools that can manage multiple APs are hard to find and also too expensive to the public. To solve this problem, this paper discusses how to install the...
In Software Defined Networking, the role of the centralized controller is paramount. Some SDN controllers adopt a distributed clustering mechanism for keeping normal operation of the whole network. Unfortunately, the data loss and the lack of consistency are unavoidable in this approach, because many controllers depend on volatile memory to store most of the important data. In case of restarting or...
Needs of new services and complexity of network are increasing rapidly nowadays. To resolve this states, this paper aim to implement VNF (Virtualized Network Function), which operates on the open network platform. And VNF is implemented based on existing open source. Especially, this paper focus on AP (Access Point) control using CoovaChilli. Also, it aims at perfect openness by contributing the open...
Open Source Hardware is widely used as enterprise standard device because it has high performance for its price. Traditional enterprise Wireless Local Area Network has the limitation of functionality and scalability by the deployed network equipment. To solve this problem, we propose ‘Web of Place Access Point’ using raspberry pi that enable to manage the scale of the network and to provide enterprise...
The use of the proxy server is being extended steadily in order to provide various web services and improve the quality of web service. However, passing many proxy servers may degrade the quality of web service, because of increasing HTTP message processing time. In this paper, we propose a scheme that bypasses many proxy servers constituting proxy chain. Furthermore, we perform network simulation...
Recently, as the smartphone market is growing rapidly, the amount of using QR Code with smartphone is increasing together. This paper proposes a new method for improving the rate of QR Code recognition on smartphone. In some angles, sometimes, a few applications cannot recognize QR code. So, this method make it possible to recognize the QR Code any angle. In order to find an original QR Code we proposes...
