Problems solved by technology

[0004] (2) Public tragedy (Tragedy of Common) phenomenon: Due to the spread of a large number of identical resources on the P2P network system, the shared resources have gradually converged for a long time, no one is willing to share new resources, and a large number of duplicate resources are used as non-exclusive Common resources are used unchecked by most network nodes
This kind of incentive mechanism model is more complicated, and it is more difficult to implement.

Embodiment Construction

[0057] Each node in the P2P network must provide services to the entire network according to the initial agreement, including shared storage space and available resources, and can also enjoy the storage space and resources provided by other nodes in the network. The differences between different incentive mechanisms are mainly reflected in the utility function, the definition of the relationship between the node's ability to enjoy the service and the node's contribution to the system, and the selection of measurement points. When designing the contribution value algorithm, it is necessary to encourage the enthusiasm of the nodes as much as possible to ensure the continuous and stable operation of the system.

[0058] The present invention adopts the resource size and sharing rate that the current node shares with other nodes as the main design factors. Nodes with more shared resources will obtain more contribution values; higher sharing rates will also obtain more contribution ...

Abstract

The invention relates to a campus network P2P incentive method based on contribution values. According to the method, current nodes serve as main design factors for resource sizes and sharing rates shared by other nodes, and nodes with more shared resources can obtain more contribution values; and the higher the sharing rates are, the more contribution values can be obtained. The method takes other factors such as single shared resource sizes, sharing time and resource classification into consideration simultaneously. According to the method, various factors are combined to serve as the basis of single node contribution values, accordingly, resource qualities and fairness, economy, differences and diversities of incentive mechanisms are improved.

Description

technical field [0001] The invention relates to a P2P incentive method for a park network based on a contribution value, which is applied in the technical field of computer networks. Background technique [0002] Peer-to-peer network (P2P) is an open and anonymous network composed of several cooperating computers. From the point of view of service, all nodes in this network are equal, and each node is both a service provider and a service recipient. The traditional P2P system does not provide an effective incentive mechanism. Each node in the network is not subordinate to each other. They are all self-managed and independently determine resource contributions, so that most nodes show selfish behavior, which leads to the existence of a large number of the following two phenomena : [0003] (1) Free Riders [1] Phenomenon: Most nodes are unwilling to share their own resources, but use free and available resources provided by other nodes as a free rider. [0004] (2) Public ...
