46896 然后，可信中心服务器代理用户以目标类型兴趣点记录号发起查询， Then atrusted intermediate server, replacing of the user, issued a query request with a record number instead of the query contentto the LBS server.
46897 LBS 服务器无法确定用户真实位置及查询内容，实现了保护隐私的秘密检索； The LBS server could not determine which kind of PoI the user was interested in or which road sectionthe user was locating on, and therefore the scheme achieved private information retrieval.
46898 最后，对查询准确性、数据分组量和处理时间进行了对比分析实验， Finally, the efficiency in themetrics of query accuracy, communication overhead and processing time was also analyzed.
46899 性能分析证明了所提方法具有位置不可追踪性和查询内容不可关联性。 By the performance analysisand extensive experiments, the proposed scheme is proved to be location untraceable and query content uncorrelation.
46900 为了降低内容中心网络的缓存内容冗余度和提高缓存内容命中率，提出一种基于节点中心性度量的缓存机制(CMC)。 In order to reduce the cache redundancy as well as increase the cache hit ratios in content-centric networks, thenode centrality metric based caching mechanism (CMC) was proposed.
46901 CMC 利用控制器获取整个网络的拓扑结构和缓存空间空闲率， CMC utilized controllers to obtain the topologyof the whole network and the idle rate of cache space.
46902 根据拓扑的连接关系分别计算各节点的度中心性、紧密中心性和介数中心性，并将这 3 个度量和缓存空间空闲率作为缓存节点选择的重要指标。 According to the connection relation of the topology, the degreecentrality, closeness centrality and betweenness centrality of nodes were calculated. When CMC choose the cachingnodes, it took the three metrics and the idle rate of cache space into account.
46903 仿真实验表明，与传统内容中心网络（CCN）缓存机制相比，CMC 可以有效地提高缓存内容命中率，降低获取内容的跳数和平均请求时延。 Simulation results show that CMC can effec-tively increase the cache hit ratios and reduce the content fetching hops and average request delay compared with the tra-ditional routing algorithms in CCN.
46904 以 agent 负载能耗均衡度和网络总能耗为指标构建多移动 agent 协作规划模型， The multi mobile agent collaboration planning model was constructed based on the mobile agent load balanc-ing and total network energy consumption index.
46905 为了尽可能延长网络生存周期，给出基于网络覆盖率的节点休眠机制，在满足 WSN 网络覆盖率要求的同时，采用较少节点处于工作状态。 In order to prolong the network lifetime, the network node dormancymechanism based on WSN network coverage was put forward, using fewer worked nodes to meet the requirements ofnetwork coverage.
