基于多服务属性的网格信誉资源选择模型

Grid reputation resource selection model based on multi-service attribute

通过分析网格资源访问过程中信任管理问题,借鉴人类社会的信任关系,考虑主观信任的模糊性、复杂性和不确定性等因素,通过对网格资源需求的多方面考虑,引入服务属性概念,提出一种基于多服务属性的网格信誉资源选择模型.服务请求者根据自身喜好对各服务属性进行模糊综合评判,选择交易对象.交易结束后,服务请求者根据服务质量判断服务提供者是否可信,并进行信任度更新.仿真实验表明,该模型能较好地抵御恶意实体的攻击,提高资源选择成功率.

Considering the ambiguity,complexity,and uncertainty of subjective trust and considering the demand on grid resources,we propose a grid reputation resources selection model based on multi-service attribute by analyzing the trust management in the process of grid resources access,learning from human society,and introducing the concept of service attribute.The service requester will comprehensively evaluate the service attribute based on their preferences to select transaction object.After the transaction,the service requester judges the credibility of service provider based on the actual quality of service and then measures the credibility.Simulation results show that the model can withstand attacks of malicious entities and raise the success rate of resource selection.
