A two-tier overlay network model is presented in this paper. Some consecutive nodes form an unstructured group and different groups are connected by a globally structured overlay with the Chord protocol. The model uses the Hilbert-based level search and the dynamic load balancing policy of a two-tier ring structure on top of the overlay network.This strategy has not only the characteristics of load balancing but also enough flexibility for searching.

Chord模型可以保证搜索系统中特定数据对象的跳跃次数在O的范围内，但只能根据数据对象的键进行准确匹配查询，不支持多关键字、部分关键字、通配符或是参数取值区间组成的复杂查询[1]；其次，相容散列的理论证明了当系统中有N个结点和K个键值的情况下，在每个结点上运行O个虚拟结点时，每个结点的键值范围可以无限趋于K/N。

The proposed robust road main direction detection method consists of initial main direction extraction based on the direction histogram of structure tensor and precise direction detection on vectorized edge image. Experiment results demonstrate its robustness and precise. The proposed Gibbs-sampling-based method models road network with marked point process and can effectively extract road network with initial configuration. However it is slow and still can not deal with single and isolated road segment. These problems can be solved by the real-time method. And experiments verify that the real-time method is fast during extracting road segment.
