CC2530상에서 Z-Stack을 이용한 거리 측정 센서 네트워크 디자인 및 구현
김병순(Byungsoon Kim),강오한(Oh-Han Kang) 한국디지털콘텐츠학회 2014 한국디지털콘텐츠학회논문지 Vol.15 No.2
As there are few documents about how to design and implement a sensor network with Z-Stack, developers can get information from developers community on Internet. That takes longer time to develop the network. This paper presents how to design and implement a range measuring sensor network with Z-Stacks Generic application and ultrasonic sensors based on CC2530, and then show experimental results through the implemented network. This work will make less time for a developer to implement a sensor network with Z-Stack.

Wireless sensor networks consist of resource constraint devices which typically send data measured by sensors attached to the end devices towards a coordinator. The most often used medium access control protocol used in wireless sensor networks is the standard IEEE 802.15.4, where it is wireless standard introduced for low power, low cost wireless communication with moderate data rates. In this paper, we present implementation of both the IEEE 802.15.4 protocol stack and UART interface on the TI CC2530. We show that data via UART of our implemented IEEE 802.15.4 board are transmitted correctly in terms of captured frames.

Wireless sensor networks consist of resource constraint devices which typically send data measured by sensors attached to the end devices towards a coordinator. One of the best solution for wireless sensor networks is ZigBee, where it is wireless standard introduced for low power, low cost wireless communication with moderate data rates. In this paper, we present porting of Z-Stack and implementation of UART on the TI CC2530. We show that our implemented board works correctly in terms of transmitting and receiving data via serial port.
A Delivery Scheme for Hybrid Ferry-Mobile Node Messages in DTNs
김병순(Byungsoon Kim),이봉규(Bongkyu Lee) 한국정보과학회 2009 정보과학회논문지 : 정보통신 Vol.36 No.2
기존 메시지 페리 방법에서는 페리만이 분리된 네트워크 사이에서 메시지를 전달한다. 이 논문에서는 지연 허용 네트워크에서 메시지 전달 지연을 줄이기 위해 페리와 이동 노드 모두가 메시지를 전달하는 새로운 방법을 제안한다. 우리는 메시지 전달 지연, 처리율, 페리 버퍼와 이동 노드 버퍼 사용량을 통하여 기존의 메시지 페리 방법과 성능을 비교평가 한다. In traditional message ferrying schemes, only ferries carry messages between partitioned networks. In this paper, we propose a new approach to make both ferries and mobile nodes carry messages so that we reduce message delivery delay in disruption tolerant networks. We evaluate our scheme against conventional message ferrying in terms of message delivery delay, throughput, ferry buffer usage and mobile nodes buffer usage.

Along with international regulatory action to protect the global environment, the refrigeration and air conditioning industry has been challenged continuously to curb the use of fluoridated greenhouse gases. With the signing of 197 countries in the October 2016 Kigali Amendment, legal regulatory policies for F-gas reduction are accelerating. EU countries are introducing F-gas quota system to strengthen environmental regulations on HFCs, which have a significant impact on global warming. These regulations are affecting domestic refrigerators, heat pump dryers and airconditioners in which HCFC & HFC refrigerants were used. And It is directly weakens productive competitiveness in the international market. Currently, other advanced countries such as EU and USA are taking the lead in the global refrigerant regulations. They are stepping up new alternative refrigerants and some of them are already available in the market. We also have to understand these new directions about Global warming and refrigerant, and need to prepare before it is too late. Therefore, I would like to introduce recent trends of refrigerant regulation&polish in different countries.
