人群网络是一种特殊的容迟网络。在这种网络中,人通过携带随身移动通信设备,利用短距离无线电进行通信。对于这种网络路由算法的研究,一个关键的方向就是研究设备的载体--人群网络的拓扑结构特点。由于人的移动性导致网络拓扑结构不断变化,一个特定的路由算法很难一直保持好的性能。因此,为了能更好的进行路由算法设计,提出对人群网络拓扑结构变化进行分类。 Crowd network is a special tolerance network. In such a network, people communicate by using short-range radios by carrying portable mobile communication devices. For this kind of network routing algorithm research, a key direction is to study the carrier of equipment - the topological structure of crowd network. Due to the changing topology of the network caused by human mobility, it is difficult for a particular routing algorithm to always maintain good performance. Therefore, in order to better design the routing algorithm, this paper proposes to classify the changes of population network topology.
