行踪分析
行踪分析-
通过实际的行踪数据分析发现，采用中心性作为路由度量尺度具有幂律分布的特点。
It can be easily implemented with low overhead of control . ( 2 ) Through analyzing trace data in real world , we can observe that centrality has the characteristics of approximate distribution of power law . Centrality is used as routing metric in delay tolerant networks .
