  • In this paper we propose a new efficient authentication protocol that reduces overheads of computation for digital signature generation/verification on mobile devices in the Personal Area Network (PAN). In particular, we focus on eliminating the traditional public key operations on mobile devices without any assistance of a signature server. Moreover, the proposed protocol provides a simplified procedure for certificate status management to alleviate communication and computational costs on mobile devices in the PAN.

  • With the progress of portable appliances such as cell phone and handhold PC, the popularization of Personal Area Network (PAN) and the diversification of services that are based on Personal Mobile Gateway (PMG) . To use home services at any time regardless of their Position, it needs a virtual home network that a home network and outside networks are finally integrated. Although interoperability among home appliances reached their service stage, research for services and middleware for new small scale network such as PAN is at an early stage. Traditional home network service/connection methods, terminal control schemes, and middlewares must be extended to accommodate PMG-based PAM. In this paper, we propose an integrated virtual home network Platform that guarantees seamless connections between home network and PAM. We also analyze indispensable functions and presents functions that should be added existent home gateway or home sewer by function.

  • Recetly, the term Personal Public Key Infrastructure (PKI) was introduced to supprot reliable and authenticated service in a Personal Area Network (PAN). However, traditional public key signature schemes and certificate status management are not suitable for a PAN environment since mobile devices that constitute the PAN have limited computing capability. In this paper, we propose a new scheme that efficiently provides signature generation and certificate status management for mobile devices. Based on hash chain technique, we intend to reduce computational overhead on signature generation, and further, to minimize communication overhead for managing certificate status.

  • 하나의 기술을 넘어 인간 생활 자체로서 발돋움한 네트워크는 인터넷을 바탕으로 하여 Home Area Network에 이어 Personal Area Network란 신개념을 창출하였다. 이는 단순히 기술의 발전을 통한 개인 생활의 효용성 증대란 의미 외에 네트워크 기술이 해결해야 할 필연적인 과제로서 이에 대한 시장과 관심은 점점 더 커져가고 있는 실정이다. 본 고에서는 PAN의 구현에 필요한 다양한 무선 기반의 기술들을 소개하며, 단순한 근거리 무선 통신 기술을 넘어 이제는 3세대 이동 통신망의 주요 요소 기술로까지 발전하고 있는 Bluetooth 기술이 어떠한 연구와 방식을 통해 개인 정보망에 적용될 수 있는지 알아보고자 한다.

  • The usage of LED(Light Emitting Diode) has been rapidly increased and energy efficient management of LED light system is regarded as an important technology to enhance the energy efficiency. In this paper, we design and implementation of LED lighting controller which can control the LED lighting by using the wire and wireless communication technology based on the LAN(Local Area Network) and PAN(Personal Area Network). The implemented system can reduce the cost of LED lighting installing and avoids complicated wiring problem. And it is possible to minimize power consumption through automatic or manual LED control that they wished. In experimental results, the implemented LED lighting controller was satisfactory for all of the desired functions.

  • IEEE 802.15.4는 저전력 무선 개인 네트워크(LR-WPAN, Low Rate-Wireless Personal Area Network)를 위한 표준으로 무선 센서 네트워크 기술에서 광범위하게 사용되고 있다. 그러나 IEEE 802.15.4는 멀티홉 네트워크나 여러 개의 PAN(Personal Area Network)으로 구성된 네트워크에 대해서는 상세하게 기술하고 있지 않다. 본 논문에서는 IEEE 802.15.4를 기반으로 하는 ZigBee RF4CE 네트워크에서 사용하는 multiple star 토폴로지를 주목하였다. multiple star 토폴로지처럼 여러 개의 PAN 간에 통신이 이루어질 경우, 이를 에너지 효율적으로 수행할 수 있도록 하는 비컨 간격(Beacon Interval)과 슈퍼프레임 시간(Superframe Duration)을 분석한다. 이를 위해 QualNet 시뮬레이터를 이용하여 multiple star 토폴로지 네트워크를 형성하고, 비컨 간격과 슈퍼프레임 시간을 결정하는 요소에 대해 분석하였다.

  • In this paper, a current-mode analog variable finite-impulse-response (FIR) filter with variable tap coefficient circuits is proposed for frequency selective wireless personal area network(WPAN) system or terminals. From the circuit simulation the operation of the 7-tap FIR filter is confirmed. The 0.0625-step tap coefficient circuit is designed and fabricated with $0.8[{\mu}m]$ CMOS technology. The proposed FIR filter has a variable length of taps and variable coefficients, so it has a potential for being used to frequency selective WPAN system or frequency selective wireless communication terminals.

  • The proposed technique uses cyclic frame structure, where three periods such as beacon period (BP), mesh contention access period (MCAP) and slotted period (SP) are in a data frame. This paper studies on a mechanism to allow communication nodes (6lowpan) in a PAN with different logical channel for global healthcare applications monitoring technology. The proposed super framework structure system has installed 6lowpan sensor nodes to communicate with each other. The basic idea is to time share logical channels to perform 6lowpan sensor node. The concept of 6lowpan sensor node and various biomedical sensors fixed on the patient BAN (Body Area Network) for monitoring health condition. In PAN (hospital area), has fixed gateways that received biomedical data from 6lowpan (patient). Each 6lowpan sensor node (patient) has IP-addresses that would be directly connected to the internet. With the help of IP-address service provider can recognize or analyze patient data from all over the globe by the internet service provider, with specific equipments i.e. cell phone, PDA, note book. The NS-2.33 result shows the performance of data transmission delay and data delivery ratio in the case of hop count in a PAN (Personal Area Networks).

  • IEEE 802.15.4 기반의 무선 PAN(WPAN: Wireless Personal Area Network)환경에서 기존에 제안된 전송 전력 제어(TPC: Transmission Power Control) 알고리즘은 수신 신호의 세기를 기반으로 반복 전송을 통하여 적합한 최소 전송 전력을 결정하는 방법으로 진행되어 왔다. 이러한 방법은 통신 채널의 변화가 잦은 지역에서는 재전송률이 높아지고 전송 품질이 떨어지는 단점을 가지고 있다. 따라서 본 논문에서는 IEEE 80215.4에서 제공하는 링크 품질 지표(LQI: Link quality indicator)값을 바탕으로 최소 전송 전력을 결정하여 재전송률을 줄이고, 통신 채널 변화에 보다 능동적으로 대응할 수 있는 새로운 전송 진력 제어 방법을 제안하고자 한다.
