Constructing method of incentive mechanism based on recommended node credibility computation

Abstract

The invention relates to a constructing method of an incentive mechanism based on recommended node credibility computation, which is a strategic method and is provided by updating the recommended node credibility of an environment and combining the recommended node credibility with resource node trust value computation. The invention aims to incent resource nodes of a network to evaluate other nodes by updating the credibility of recommended nodes and also can effectively solve the problem of joint cheat between middle nodes in a trusting model of the network. The constructing method comprises the following steps: firstly, introducing a resource node trust value nearness variable; computing the nearing degree of a resource node trust value; then introducing a time decay weighted average variable of the resource node believe value, wherein time decay is taken as a weight factor to average a resource node history believe value in a weighted way; and finally, computing a comprehensive believe value of the resource nodes by combining the resource node believe value nearness variable with the time decay weighted average variable. The method prevents the excessive simpleness of a previous method and has high computation result credibility.

Description

technical field [0001] The invention is a strategic method based on the trust problem in the P2P (peer-to-peer computing Peer-to-Peer) network in an open network environment, mainly used to solve the incentive problem in the trust relationship, and belongs to peer-to-peer computing and information Safe technical application fields. Background technique [0002] Peer-to-peer network (P2P) is a kind of network architecture method that has risen rapidly in recent years. There is no central server in the P2P network, and all nodes are equal. Each node acts as a server, providing services for other nodes, and at the same time as a client, enjoying the services provided by other nodes. They can join or exit the network at any time , providing or receiving services, and information can be directly shared between nodes. Compared with the traditional client / server (C / S) mode, P2P technology can effectively utilize the idle resources on the network and avoid the bottleneck problem c...
