摘要
节点的主动贡献对于P2P系统的成功运行,具有重要的作用。针对P2P中一些节点不愿意贡献资源等问题,提出一种基于信誉的资源分配策略,不同于以往的基于信誉的机制,文章是通过该策略主动选择合适的服务请求提供者,这种资源分配策略的收益是两方面的,首先把更多的资源进行共享,给更多的请求节点,其次最大化满足竞争节点。通过实验分析可知,贡献高的节点,节点的信誉和满意度都较高。
The nodes＇ contribution is important for the success of P2P network. There are some nodes which don＇t like to contribute resource. A trust-based resource allocation policy （TRAP） is presented for resolving those non-cooperation nodes. It is different from other mechanisms based on the reputation. The TRAP forwardly selects appropriate sever requesting nodes. This resource allocation policy has two sides. Firstly, more resources are sharing to satisfy the requesting nodes. Secondly, the satisfaction of nodes is maxed. The experiment result shows that the nodes which have high contribution have high reputation and satisfaction.
