Research Of Peer-to-Peer Communication Technology Based On Internet Of Things

Internet of Things is a new type of network, which is on the basis of traditional telecommunication network and the internet. Internet of Things let all ordinary physical objects which can be individually addressed access network. The data center is the core of the Internet of Things, responsible for the control and management of the nodes of Internet of Things. Thus, it is crucial to build a stable, robust and efficient data center of Internet of Things. Because the existing data center of Internet of Things depends on services distributed servers heavily, the load of Internet of Things system is not balanceable. There is another problem is the nodes of Internet of things in different network environment can’t communicate directly. For the existing problems in the data center of the Internet of Things, this paper study the Peer-to-Peer communication technoloy of Internet of Things, and design a kind of JXTA-P2P proxy to realize Peer-to-Peer network mode of Internet of Things.Firstly, this paper researches on Peer-to-Peer communication technology and the architecture of data center of Internet of Things. There are some problems in system of Internet of Things, that the load of system is not balance and the nodes in different network environment can’t communicate directly.Based on hybrid P2P network model, this paper put forward the way to solve the problem of data center, and design Peer-to-Peer network architecture of Internet of Things. The nodes in different network environment can establish connection through the center P2P server and company P2P server. Transit server will not work when a connection is established successfully. Then, the nodes can communicate directly.Secondly, this paper studies the system structure of JXTA platform, the core protocol, the key components and the principle of nodes using the JXTA pipes to communicate. According to the EPC coding regulation of Internet of Things, this paper improves the JXTA search mechanism, so as to search and find the nodes of Internet of Things easily.Thirdly, based on Peer-to-Peer architecture of Internet of Things, this paper designs a kind of JXTA-P2P proxy. The proxy is divided into the central module, the company module, JXTA and SOAP switching module, and JXTA and SOCKET switching module.Through the JXTA-P2P proxy, the nodes in different network environment can realize communication directly, and reduce the load of services distributed server of data center.Finally, based on physical nodes transmit data under the action of agent module, to verify its validity, reliability, and ductility, this paper tests the JXTA-P2P proxy under the application environment of Internet of Things.This paper studies the Peer-to-Peer communication technology based on Internet of Things. According to the EPC coding regulation of Internet of Things, this paper improves the JXTA search mechanism and designs a kind of JXTA-P2P proxy. By the proxy, it can reduce the load of services distributed server of data center, and the nodes on different network environment of Internet of Things can communicate directly, which can penetrate firewall, router, gateway and other network edge.
