  • In this paper, LAN Access Point is realized by making out bluetooth protocol stack in Linux Kernel, porting Linux in an embeded system employed bluetooth module. Hardware for a general-purpose embeded system is designed and Linux Kernel is ported after deploying Bluetooth Module. Also, Boot loader for system booting and management is composed, and Kernel is modified to meet with the system. Finally, Ethernet devise driver is made out, and bluetooth protocol Stack and Lan Access Point are realized. The possibility of TCP/IP communication through LAN Access Point to PC employed Bluetooth module, which is considered as client, is evaluated. From the evaluation results, we can see that the performance in Telnet FTP, Web browsing through Bluetooth LAN Access Point is satisfactory.

  • This study analyzed guidelines and instructions for access points representing works and expressions in RDA. The preferred title for the work is used as the basis for constructing an authorized access point to represent a work or expression. If applicable, the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity with principal responsibility for the work. The variant titles for the work are used as the basis for constructing variant access points to represent a work or expression. If the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity responsible for the work, the variant access points are constructed by combining the variant titles for the work to the authorized access point, and by using only the preferred title for the work. Besides, RDA provides instructions to construct the controlled access points for special works like musical works, laws, religious works and others, but the general principles for these works are same as the above instructions. The authorized access points for works and expressions in RDA are almost same as the main entry headings in AACR2.

  • This study tries to describe personal name access point control ontology for the American novelist Mark Twain using RDF/OWL axiom to control access point based on the ontology. The Axiom used in this study are disjoint with class, domain and range, property cardinality, inverse functional property, individual and literal data property. As a result, in the ontology environment we can accept various access points as equal access points exclusive of authority heading and heading concept. It can successfully describe Mark Twain's personal name access point control ontology and display using the OntoGraf.

  • In this paper, we aim to design and implement supporting IPv6 Bluetooth Access point(AP) in Linux. Bluetooth is a cable replacement technology designed for short range ad-hoc connections, which most likely change the way we handle and access information in the near future. In Personal Area Network(PAN) mobile devices need many IP address space, then we need next generation Internet Protocol(IPv6). We designed Bluetooth Access Point with Bluetooth stack and MAC bridge function in Linux. The implementation tested on Linux system based on Bluetooth Access Point with other Bluetooth devices.

  • In this paper, we propose a new type of integrated wireless control system using a cloud-based AP Controller. With this system, network administrator can control wireless network in head office and branch hierarchically. In head office, they have an AP Controller Manager, it can control all Access Points, Access point Controllers in their networks. In addition, if we need to install new Access point Controller because of the increasing number of Access Point, the process of making virtual Access point Controller can be automated. This paper presents an architecture of the integrated wireless control system, as well as describes its components and protocols.

  • IEEE 802.11 규격에 따른 무선랜은 사설망에서 사용됨은 물론, 공중망 사업자들에 의한 핫스팟 서비스까지 제공되면서 수요가 더욱 늘어나고 있다. 사용자가 늘어남에 따라, 이에 대한 보안의 중요성 또한 늘어났다. IEEE 802.1X는 랜 접속 서비스를 받고자 하는 시스템이 인증을 거쳐 랜을 사용할 수 있도록 함으로써, 허가 받지 않은 사용자가 무단으로 사용하거나 도청하는 것을 어렵게 한다. 기존의 Linux 용 access point 디바이스드라이버에 802.1X 가상 포트를 추가하고, 이를 제어하는 가상 포트 제어기를 통하여, 사용자 인증 기능이 추가된 access point를 설계, 개발하였다. 개발된 시스템은 embedded Linux 형태의 access point고 사용되어 질 수 있다.

  • In this paper, we describe a development of a Bluetooth Access Point for the WAN connection of home network devices. Especially, users can access the PSTN at home instead of expensive digital cellular network through the AP, using the 'one-phone', which is the Bluetooth enabled cellular phone. The simultaneous benchmark test about telephone service and LAN access service shows the perfect compatibility and reasonable performance of the access point. The one-phone service can become a convergence of wired and wireless communication through the AP.

  • This study proposes a national cooperative model of access point control, that enables local systems to utilize national access point control record, without creating their own authority records. In order to applying this model, a client/server system is developed using SRU (Search and Retrieve URL Service) protocol. The suggested access point control system will be a cost-effective and time-saving model for the local system, and will be more flexible and extensible with concept of access point control, XML record format and SRU protocol.
