中文摘要：

物联网中许多应用都涉及实体搜索定位。由于物联网中实体类型、通信协议、隶属机构、信息存储组织结构的差异导致了物联网被割裂为相互独立，互不协作的子网络，资源得不到有效利用。基于地标系统的实体搜索定位体系结构是一个开放的、多层多级的、分布式的体系结构，可以有效的整合物联网中的海量实体的信息和各种实体搜索服务。在此体系结构的基础上提出的MCOUS算法采用本地搜索与全局搜索并发进行的多路径搜索策略，高效获取物联网中任意类型实体的位置信息。

英文摘要：

Many applications involve object search and orientation in Internet of Things. The types of objects, the communication protocols between objects, the owners of objects, information storage of objects are different in the Interact of things. Those differences induce that Internet of things is fragmented to many independent subnets. Resources are usually not sufficiently utilized. In this paper, the architecture of object search and orientation based on landmark system is open, muhilayer, multistage and distributed. The architecture organizes the massive information objects and object search and orientation services effectively. The MCOUS algofithm based on the architecture uses multi -path Concurrent search strategy, namely local search and global search are concurrent execution. The MCOUS algorithm can access to location information of any type of object efficiently.
