借鉴生物神经内分泌和免疫系统突现和自进化机制,提出了一种普适服务突现的服务组合方法。移动Agent设计为具有免疫行为的生物实体,并代理普适服务,生物实体通过亲合力(由生物实体匹配强度、服务质量和信任度决定)匹配形成网络,普适服务组合是由突现形成的生物实体网络提供,服务突现可以动态的调整其中的服务,这种方法自组织完成服务的动态组合和自主管理等工作。仿真结果表明方法具有良好的性能和对动态环境变化的适应性。
Inspired by the characteristics of system emergence and self-evolution in biological neuroendocrine and immune system, a composition method of service emergence was proposed in pervasive service environments. Mobile agent was designed as a bio-entity with biological immune operation, which was applied to represent pervasive service, bio-entities construct network through affinity. The measure of the affinity is based on the matching strength, the service quality score and the trust. The pervasive service composition was provided by emergent network of bio-entities. Service may be added or removed dynamically in service emergence. The method completed a series of work from composition to management autonomously. It shows a good performance and adaptability to dynamic environment with the simulation result.
