In the past several years there has been increasing the studies using P2P technology in the distributed system areas. In these P2P systems, the server to support the contents-information have less overloads than the composed system as the server to have resources generally. In this paper, we propose the system to support a social network P2P service based on the social network P2P system. The object of this study was to widen the use of this menu system to determine the price based on visual information by a software agent. Therefore, this system is suitable for micro, small and medium industries in the use of P2P servers and is more usable system interface for owners than previous study.

In this paper, we propose the system to support a menu based on the social network P2P system.

Therefore, this system is suitable for micro, small and medium industries in the use of P2P servers. This system is more usable than previous study.

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.

This paper describes the design and implementation of video conference system using hybrid type P2P(Peer to Peer). The proposed video conference system has hybrid type P2P architecture based on a client-server and P2P(Peer to Peer), where client-server is used for exchange of account management, client list and status information and P2P is used for the real time video conference. The proposed video conference system decreases the traffic of server, and cuts down the load of a network. Because the multimedia data is decentralized to client by P2P. Also, this system is tested by the multi-party video conference system using communication protocol and application software through high speed networks.

Chord system, structured P2P system based on distributed hashed table, didn't consider the mobility of mobile device. Mobility of mobile node may cause performance falloff of both mobile node and P2P network. Not only Chord system but also the greater part of P2P system didn't consider the mobility of mobile node. Recently it is researched on mobility in P2P system. In this paper, it proposed the method of the supporting mobility in chord system. Mobile node joins to the P2P network through the stationary node meaning the parents node. Mobile node require or offer the service for the parents node.

P2P (Peer to Peer) is part that is discussed much in the latest Internet and is interested. P2P changes the structure of Client-Server into Information sharing between client that is the structure of p2p. But perfect P2P system has many problems awaiting solution. In this treatise we can realize network communication to compose one virtual server and one virtual client which is intergrated several client and distributed computer that decentralize network traffic into the traffic of several pc by sharing resource and cpu between client. Our nam purpose is not real P2P system but realization, organization of the P2P internet system which is composed by distributed computing and network load balancing in P2P internet system environment.

P2P technology is the concept to share resources efficiently in distributed environments that a lot of research is underway. a lot. In these P2P systems, the server to support the contents-information have less overloads than the composed system as the server to have resources generally. In this paper, we suggest a P2P system to support conveniences to choice time for users that were connected with the information of joint-buying based on social network. Social networks based on co-purchasing information and price alerts using the P2P system is provided by the peer, this relay information is provided by the P2P server.

A P2P technique is the concept to share sources efficiently in distributed environment that is studying a lot. In these P2P systems, the server to support the contents-information have less overloads than the composed system as the server to have resources generally. In this paper, we suggest a P2P system to support conveniences for users that were connected with the information of joint-buying based on social network. The joint-buying information based on social network is supported by peers using a p2p system and these information to intermediate are supported by a P2P server.

Though P2P network systems are widely used, not so much research has been done on security issues. One of the serious problem in P2P network is the authentication problem. To resolve this problem, we introduce a new concept, a "self-reputation system" in which a user manages her own reputation. We define self-reputation systems by presenting several requirements. We also give one instance of self-reputation system. The proposed instance satisfies the requirement including the prevention of erasing and the platform independence.ependence.

In the connected environment by network, clients shared resources as that requested the file that a server had, but P2P system is alternative because of the overload of servers. To improve the performance of this P2P system, we are studying about that. In this study, we can improve a usability for users using P2P search system, and suggest a group search algorithm based on a preprocessing search.
