Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] The invention constructs an unstructured overlay network with a k-faction community structure by taking the k-faction as the basic unit. In this overlay network, each node belongs to only one k-clique. In order to realize this topology, two different nodes are needed, one of which is the central node, referring to the initial node when each k-clique is formed. The other is the common node, which realizes the interconnection between nodes within the faction with the support of the central node.

[0050] Ordinary nodes can act as external nodes at the same time. External nodes refer to nodes that contain information of different faction nodes among neighboring nodes. In order to access resources of different factions, each node stores a list of external nodes, recording the addresses of all external nodes in its faction.

Abstract

The invention provides an unstructured mobile peer-to-peer overlay network, which can overcome the shortcomings of poor topological structure stability and anti-disturbance of the existing mobile peer-to-peer overlay network. It includes at least one k-faction subnetwork, the k-faction subnetwork includes at least one central node, and also includes a plurality of common nodes; any one of the common nodes has at least one communication path with one central node; all Nodes provide their own resource indexes that are readable to other nodes, and all nodes store a faction resource index list, which contains information about all neighboring nodes. The present invention also provides a construction method of the above-mentioned unstructured mobile peer-to-peer overlay network, and a maintenance method when a node is pushed out or fails.

Description

technical field [0001] The invention belongs to the field of information communication, and specifically relates to an unstructured peer-to-peer overlay network in the field of mobile communication. The invention also provides a construction and maintenance method for the unstructured mobile peer-to-peer overlay network. Background technique [0002] The successful application of peer-to-peer (P2P) technology in file sharing has made P2P networks highly valued by researchers, and some classic P2P overlay network construction algorithms have been proposed, such as Gnutella and Chord. The construction of an overlay network is the basis of P2P network routing protocols, load balancing, and security authentication. Whether this problem can be solved well is the key to determining the performance of a P2P network. In recent years, with the large-scale application of mobile Internet devices, research on mobile peer-to-peer networks has become a hot spot. Due to the particularity ...
