上下文信息的广泛使用需要在广泛的计算中有效的广泛查找服务。在本文中,我们提出语义上下文空间(SCS),这是一个语义覆盖网络,可有助于在分布式环境中有效搜索上下文信息。 SC中的同伴根据其本地数据的语义进行分组,并自行组织成一维环空间。上下文搜索请求仅路由到适当的语义簇,从而减少具有无关紧要的上下文数据的同行的不必要的搜索成本,并增加了可以快速找到上下文数据的机会。通过在语义集群中探索并行性,可以快速找到搜索请求。我们的仿真研究证明了SC的有效性。
The widespread use of context information necessitates an efficient wide-area lookup service in pervasive computing. In this paper, we present semantic context space (SCS), a semantic overlay network that facilitates efficient search for context information in distributed environments. Peers in SCS are grouped based on the semantics of their local data and self-organized into a one-dimensional ring space. Context search requests are only routed to the appropriate semantic clusters, reducing unnecessary search cost on peers that have irrelevant context data, and increasing the chances that the context data will be found quickly. By exploring parallelism in a semantic cluster, search request can be found quickly. Our simulation studies demonstrate the effectiveness of SCS.
