The cloud computing are provided various ways for accessing resources and services through collaboration. In this paper, we present a cloud computing model for collaboration in cloud environment. By introducing a model, it is possible to introduce and develop an application required for the database and business services. SaaS model can be applied overall or partially. In particular, business operations need various software. Since cost reduction and applying immediate service are available, it is possible to realize the business environment and high quality service.

Jung, Yean-Woo,Cho, Seongsoo,Lee, Jong-Yong,Jeong, KyeDong The Institute of Internet 2015 International Journal of Internet, Broadcasting an Vol.7 No.1

Generally, the current commercial cloud system is hosted by the centralization large datacenter. However, the other clouding forms existed and one of them is the P2P cloud. The P2P Cloud is a distributed systems, is freedom to join and leave and is possible to provide the IaaS. Commonly, P2P Cloud System is based on Pure-P2P System. Since a number of connection paths exist, it has a high reliability and easily scalability of the network. However, there are disadvantages of the slow rate of route because of looking up the all peers in order to search for the peer. In this paper, it proposes the P2P cloud system based on super-peer P2P. Super-peer P2P system has fast routing time, because of searching for cluster unit and it also can has high reliability and high scalability. We designs the super Peer cloud service and proposes the system model and Resource Allocation Algorithm for IaaS in Super peer P2P environment.

Studies have been made for the wireless sensor network protocols by a number of researchers to date. In particular, the studies as to the hierarchical protocol LEACH algorithm was concentrated. Various studies have been derived for the performance of the protocol is based on the LEACH protocol have been made. Improved algorithms have been proposed continuously. On the other hand, The performance comparison and evaluation of the improved algorithm is insufficient. Therefore, we compared the performance for the ML-LEACH (Multi Hop-Layered) and DL-LEACH (Dual Hop-Layered) been derived mainly LEACH. scalability, energy consumption, CH elected, network lifetime were selected as a Performance evaluation items.

비동기적 메소드 호출을 위한 Before/After메타클래스의 설계 및 구현

한재은(JaeEun Han),정계동(KyeDong Jung),최영근(YoungKuen Choi) 한국정보과학회 1995 정보과학회 컴퓨팅의 실제 논문지 Vol.1 No.2

많은 분야 객체 지향 환경에서 성능 향상을 위해서 멀티프로세싱이나 멀티쓰레딩(multi-threading)을 이용한 객체간의 병행 처리나 비등기적 메소드 호출 개념을 도입하고 있다. 그러나 이들은 성능은 향상되었지만 투명성이 보장되지 않는 단점이 있었다. 본 논문에서 제안한 비동기적 메소드 호출(asynchronous method call)은 메타 객체 프로토콜 기법을 도입하여 이러한 투명성 문제의 해결 방안을 제시하였다. 제안한 알고리즘은 다음과 같은 장점을 가지고 있다. 첫째, 메타 객체 프로토콜 기법을 도입하여 비동기적 메소드 호출 제어 알고리즘과 응용 프로그램 코드를 완벽하게 분리함으로써 프로그래밍의 이해가 쉽고, 제어 알고리즘의 수정이 용이하다. 둘째, 완벽하게 객체 지향 개념을 도입하고 정형화된 클래스 구조를 정의함으로써 재상용이 용이하고 기존의 클래스를 거의 수정 없이 사용할 수 있다. 본 논문에서 제안한 알고리즘은 메타 객체 프로토콜을 적용하는데 유용한 많은 기능들을 지원하고 있는 SOM(System Object Model)컴파일러를 사용해 커널상에서 멀티쓰레딩을 지원하는 OS/2환경 하에서 구현되었다. Today, in many distributed object-oriented system, it has a tendency to introduce concurrent object processing or asynchronous method calling using multiprocessing or multithreading techniques But, for setting importance on performance improvement, it has come to the problem of the lack of transparency. Asynchronous method calling, proposed in this paper, has solved this transparency problem using meta-object protocol. The proposed algorithm has the following advantages. First, we completely separated control algorithm on asynchronous method call from application program code, so it's very easy to understand program and to modify control algorithm. Second, we introduced complete object-oriented technology and fixed class hierarchy, so it's easy to use the existing class without modification. The algorithm proposed in this paper is implemented on OS/2 system that support multi-threading at kernel, and used IBM's SOM(System Object Model) that support many function useful in implementing meta-object protocol.

The Energy Efficiency of Improved Routing Technique Based on The LEACH

Ganesh Gauta,Seongsoo Cho,Kyedong Jung,Jong-Yong Lee 한국인터넷방송통신학회 2015 International Journal of Internet, Broadcasting an Vol.7 No.1

As WSN is energy constraint so energy efficiency of nodes is important. Because avoiding long distance communication, clustering operating in rounds is an efficient algorithm for prolonging the lifetime of WSN and its performance depends on duration of a round. A short round time leads to frequent re-clustering while a long round time increases energy consume of cluster heads more. So existing clustering schemes determine proper round time, based on the parameters of initial WSN. But it is not appropriate to apply the round time according to initial value throughout the whole network time because WSN is very dynamic networks nodes can be added or vanished. In this paper we propose a new algorithm which calculates the round time relying on the alive node number to adapt the dynamic WSN. Simulation results validate the proposed algorithm has better performance in terms of energy consumption of nodes and loss rate of data.

Wavelet Transform based Image Registration using MCDT Method for Multi-Image

Choel Lee,Jungsuk Lee,Kyedong Jung,Jong-Yong Lee 한국인터넷방송통신학회 2015 International Journal of Internet, Broadcasting an Vol.7 No.1

This paper is proposed a wavelet-based MCDT(Mask Coefficient Differential and Threshold) method of image registration of Multi-images contaminated with visible image and infrared image. The method for ensure reliability of the image registration is to the increase statistical corelation as getting the common feature points between two images. The method of threshold the wavelet coefficients using derivatives of the wavelet coefficients of the detail subbands was proposed to effectively registration images with distortion. And it can define that the edge map. Particularly, in order to increase statistical corelation the method of the normalized mutual information. as similarity measure common feature between two images was selected. The proposed method is totally verified by comparing with the several other multi-image and the proposed image registration.
