  • In this paper, we design a mobile phone based remote control system for PC using SKT WPAN platform and compare the presented platform with that of Windows Mobile. The usability of WPAN is one of the main issues which should be considered for the ubiquitous services. For easy development and easy use of the WPAN applications, SKT WPAN platform provides abstract WPAN APIs and WPAN Application Manager for ubiquitous services. In this paper, we implement a remote control application using the WPAN platform and show the validity of the platform comparing with other platforms. In the implemented application, we use WPAN abstract APIs on the mobile phone side and a general Bluetooth APIs on the PC for a connection between phone and PC. Through the implementation and comparison, we show that the WPAN application can be easily developed with WPAN platform.

  • The Wireless Internet services widely spread out with the developments of CDMA(Code Division Multiple Access) networks and wireless units. In contrast to the telecommunication network, WPAN (Wireless Personal Area Network) enables to transmit data and voice in personal area. Although WPAN technologies are commercially utilized, the combined services with COMA network are not so poplar up to now. Various services can be provided using the combination between COMA and WPAN. This paper presents the practical and united model between COMA and WPAN. Specially, the main focus of this research lies on the design of the Middle-ware system of a handset which could be managing both COMA and WPAN. This system used Bluethooth by WPAN. For the devices with the proposed WPAN Middle-ware, service areas of the COMA network can be expanded to WPAN, various services can be realized by the transmission of data and voice, and consequently, the user computing environment could be improved.

  • A wireless bridge is essential to transmit control and managing information to sensors or instruments from a central integrated ship area network station. In this paper, a WPAN protocol is adopted for development of a seamless N-screen wireless service in Indoor and Ship Area Networks. Furthermore, to provide the OSMU (One Source Multi Use) N-screen service through P2P streaming in the seamless WPAN protocol, a Grid-based WPAN networking technology is proposed and analyzed. The proposed Grid-based WPAN networking technology supports multi-path and fast path-setup functions for N-screen communications. The simulation results demonstrate that the proposed Grid-based WPAN networking technology outperforms the IEEE 802.15.4 based network in terms of N-screen transmission delay.

  • 6LoWPAN 센서 노드의 이동성을 지원하기 위해 기존의 Mobile IPv6 (MIPv6)와 같은 프로토콜을 활용하는 것은 저전력에 제한적 사양의 하드웨어로 구성된 6LoWPAN 센서 노드에서 구동되는 것이 현실적으로 불가능하다. 따라서 Mobile Access Gateway (MAG)가 6LoWPAN 센서 노드의 이동시 발생하는 바인딩 시그널링을 대신 처리해주는 Proxy Mobile IPv6 (PMIPv6) 프로토콜을 6LoWPAN에 적용하면 효율적으로 이동성을 지원할 수 있다. 하지만 Proxy Mobile IPv6는 6LoWPAN 이동 센서 노드와 1홉으로 연결되는 경우에 6LoWPAN 이동 센서 노드의 이동을 인지하고 Proxy Binding Update(PBU)를 하게 되지만, 6LoWPAN 센서 네트워크와 같이 멀티 홉으로 구성되는 네트워크에는 Proxy Mobile IPv6를 바로 적용할 수 없다. 따라서 본 논문에서는 기존의 1홉 단위로 연결된 6LoWPAN 이동 센서 노드의 이동성을 지원하는 Proxy Mobile IPv6 프로토콜을 멀티를 환경의 6LoWPAN 센서 네트워크에 적용하기 위한 방법을 제안한다.

  • 6LoWPAN 단위의 네트워크 이동성을 지원하는 6LoWPAN Mobile Router 들이 중첩된 네트워크를 형성하였을 때, 6LoWPAN 노드와 CN 간의 통신을 할 경우 패킷 전달을 위한 경로 최적화가 이루어지지 않는다. 특히 NEMO 프로토콜이 적용된 6LoWPAN 네트워크의 중첩된 레벨이 증가하는 경우 패킷 전달을 위한 루트가 더욱 복잡해지고 오버헤드가 커지는 문제가 발생한다. 따라서, 본 논문에서는 MANEMO 기술을 6LoWPAN 환경에 맞게 적용하여 중첩된 6LoWPAN 네트워크를 형성하지 않고 6LoWPAN Mobile Router 간에 Ad-hoc 네트워크를 형성하여 직접적인 통신이 가능하도록 네트워크를 구성함으로써 NEMO 환경에서의 터널링 오버 헤드 문제를 줄이고 통신 경로를 최적화하여 패킷 전송 지연을 최소화할 수 있는 방안을 제시한다.

  • 6LoWPAN based on IEEE 802.15.4 is a realistic standard platform for various Internet of Things (IoT) applications. To bootstrap the LoWPAN (Low-power Wireless Personal Area Network), each device must perform 6LoWPAN-ND address registration to assign a unique IPv6 address. Without adequate security mechanisms, 6LoWPAN-ND is vulnerable to a variety of security attacks including corrupted node attacks. Several security mechanisms have been proposed as a supplement to the vulnerability, but the vulnerability exists because it relies solely on IEEE 802.15.4 hop-by-hop security. In this paper, we propose and analyze a vulnerability of 6LoWPAN-ND address registration and a new security mechanism suitable for preventing the attack of damaged node. It also shows that the proposed security mechanism is compatible with the Internet Engineering Task Force (IETF) standard and is more efficient than the mechanism proposed in the IETF 6 lo WG.

  • Security in WPAN is one of the most fundamental issues to overcome the barrier of wireless environment. Although piconet security mechanisms have been defined in the WPAN standards, many remains open and are left for implementation. Koinonia is a high-rate Wireless Personal Area Network (WPAN) technology, and is developed for multimedia traffic transmission in personal area. In Koinonia WPAN, a piconet consists of one master and more than one slave, and piconet security mechanisms is not defined at all. Therefore, we propose a robust piconet security mechanism for secure communications between slaves in a piconet. Based on security requirements analysis, our proposed protocols are shown to meet the security needs for Koinonia high-rate WPAN.

  • Many researchers are now working in the Low-Rate WPAN environment. Low-Rate WPAN has as its goal the enhancing computer use by making many sensors available throughout the physical environment, but making them effectively invisible to the user. Low-Rate WPAN environment consists of wireless sensor devices that may move often. Movement of hosts results in a change in routes and the need of some mechanism for determining new routes. This paper suggests an approach to utilize location information to improve performance of a routing mechanism for Low-Rate WPAN Environment. Accordingly, we proved that the proposed mechanism results in a significant reduction in a number of routing messages when comparing with existing mechanisms.

  • IEEE 802.15.3 고속률 WPAN(Wireless Personal Area Networks)은 네트워크 구성 시 인증을 받은 노드들에게만 통신 권한을 부여함으로써 보안성을 높였다. 그러나 IEEE 802.15.3 WPAN에서 제안한 인증 방법은 사전에 각 노드들이 중앙 집중적인 키 관리자로부터 오프라인 상으로 인증키를 분배 받는 것을 가정으로 하고 있다. 이 같은 가정은 WPAN이 무선 Ad Hoc 네트워크로서 중앙 관리 노드가 부재하고 위상 변화가 유동적인 특성을 고려하지 못한 것으로 WPAN의 확장성을 감소시킨다. 따라서 본 논문에서는 WPAN의 노드들이 온라인을 통해 협력적으로 인증키를 생성하는 분산 인증키 관리 방법을 제안한다. 이 방법은 WPAN 네트워크에 확장성을 제공할 뿐 아니라 마스터 노드에 대한 보안 의존성을 감소시켜 인증 서비스의 가용성을 증대시킨다.
