A Platform for Peer-to-Peer Communications and its Relation to Semantic Web Applications

The peer-to-peer service has entered the public limelight over the last few years. Several research projects are underway on peer-to-peer technologies, but no definitive conclusion is currently available. Compared to traditional Internet technologies, peer-to-peer has the potential to realize highly scalable, extensible, and efficient distributed applications. This is because of its basic functions: resource discovery, resource sharing, and load balancing in a highly distributed manner. An easy prediction is the emergence of an environment in which many sensors, people, and many different kinds of objects exist, move, and communicate with one another; it is called the "ubiquitous communication environment". Peer-to-peer is one of the most important and suitable technologies for ubiquitous networking since it supports discovery mechanisms, simple one-to-one communication between devices, free and extensible distribution of resources and distributed search to handle the enormous quantities of resources. Peer-to-peer communication raises issues such as efficient resource discovery mechanisms and interoperation. The Semantic Web technology is one key to assuring that peer-to-peer can resolve these issues. The Semantic Web technology adequately can describe resource information. RDF (Resource Information Framework) is attracting attention for its flexibility. One of the purposes of this study is to explore a ubiquitous peer-to-peer network architecture that will allow various devices to communicate with one another across various networks. The other is to explore the applicability of the Semantic Web technology to peer-to-peer systems. We have been designing an architecture and protocols for realizing peer-to-peer networking among various devices. We are currently designing APIs for peer-to-peer applications and implementing a prototype peerto-peer networking infrastructure toward the ubiquitous communication environment. We are also considering semantic peer-to-peer applications and developing prototypes over our ubiquitous peer-to-peer network.
