Trust has become an increasingly important issue given society’s growing reliance on electronic ***-to-peer(P2P)networks are among the main electronic transaction environments affected by trust issues due to the freedom and anonymity of peers(users)and the inherent openness of these networks.A malicious peer can easily join a P2P network and abuse its peers and resources,resulting in a large-scale failure that might shut down the entire ***,a plethora of researchers have proposed trust management systems to mitigate the impact of the ***,due to the problem’s scale and complexity,more research is *** algorithm proposed here,HierarchTrust,attempts to create a more reliable environment in which the selection of a peer provider of a file or other resource is based on several trust values represented in hierarchical *** values at the top of the hierarchical form are more trusted than those at the lower end of the ***,in HierarchTrust,is generally calculated based on the standard *** via simulation showed that HierarchTrust produced a better success rate than the well-established EigenTrust algorithm.

A Credit-Based Approach for Overcoming Free-Riding Behaviour in Peer-to-Peer Networks

引用

Computers, Materials & Continua 2019年第4期59卷 15-29页

The underlying premise of peer-to-peer(P2P)systems is the trading of digital resources among individual peers to facilitate file sharing,distributed computing,storage,collaborative applications and multimedia ***-called free-riders challenge the foundations of this system by consuming resources from other peers without offering any resources in return,hindering resource exchange among ***,immense effort has been invested in discouraging free-riding and overcoming the ill effects of such unfair use of the ***,previous efforts have all fallen short of effectively addressing free-riding behaviour in P2P *** paper proposes a novel approach based on utilising a credit incentive for P2P networks,wherein a grace period is introduced during which free-riders must reimburse *** contrast to previous approaches,the proposed system takes into consideration the upload rate of peers and a grace *** system has been thoroughly tested in a simulated environment,and the results show that the proposed approach effectively mitigates free-riding *** to previous systems,the number of downloads from free-riders decreased while downloads by contributing peers *** results also show that under longer grace periods,the number of downloads by fast peers(those reimbursing the system within the grace period)was greater than the number of downloads by slow peers.
