The Research of a Structural P2P Model Based on Mobile Cellular Networks

This paper provides the C-Chord model which is a Peer-to-Peer overlay network strategy based on mobile cellular networks. In according with theories of Chord model and the landmark cluster, and making use of characteristics of cellular architectures and base stations in mobile cellular network, C-Chord model is formed master Chord ring by all base stations and formed slave Chord ring by the mobile terminal nodes in every cellular region, so C-Chord model is two-dimensional structure to mobile cellular networks. C-Chord model uses the station as the landmark node and cellular region as the landmark district by landmark cluster method, which not only implements nodes that their physical location are close are proximate in logical location, but also solves single node failure in landmark cluster method, so C-Chord model is a more appropriate Peer-to-Peer model to the mobile cellular network.
