Abstract:

Aiming at the problem of mismatch between the physical and logical network topologies in the Chord protocol which causes low efficiency of search, this paper proposes an improved P2P network protocol. This protocol takes the relationships between the physical and logical network topologies into account and constructs a hierarchical P2P network based on homogeneity. The experimental results show that the protocol can not only increase the efficiency of searching keywords but also decrease the load of the physical network.

Key words: P2P, Chord, network topology, homogeneity
