PUCC Architecture, Protocols and Applications

Compared with traditional Internet technologies, peer-to-peer has functions to realize resource discovery, resource sharing, and load balancing in a highly distributed manner. In addition to the Internet, new networks such as home network, ad-hoc network and sensor network are emerging. An easy prediction is the emergence of a new environment in which many sensors, people, and many different kinds of devices coexist, move, and communicate with one another over such heterogeneous networks. Peer-to-peer is one of the most important and suitable technologies for such ubiquitous networking since it supports discovery mechanisms, simple one-to-one communication, free and extensible distribution of resources, and distributed search to handle the enormous number of resources. Peer-to-peer Universal Computing Consortium (PUCC) was established in 2005 to develop a peer-to-peer networking platform for realizing applications in ubiquitous networking environment, which include home appliance applications. This paper presents PUCC architecture, protocols and applications.
