手机短信息传播过程和短信息寿命研究

比较了短信息在无标度网络、小世界网络和实际的短信息网络三种网络中的传播过程，寻找影响短信息传播的因素.研究发现，网络拓扑结构和手机用户的转发短信行为均会影响短信息传播过程.在无标度网络中短信息传播速率快于小世界网络和实际的短信息网络，而无标度网络的短信息寿命较小世界网络和实际的短信息网络短；网络中手机用户的转发短信息行为明显影响短信息的传播过程.同时还发现短信息寿命与网络直径有关.关键词：复杂网络短信息信息传播人类行为

Short message spreading in complex networks and longevity of short message

In order to find factors which influences on short message spreading, we compare short message propagation on three networks: scale-free, small-world and true-life short messages networks. The topology of short message network and the behaviors of mobile phone users play important roles in determining the behavior of a short message spreading. The impact of the scale-free network on the spread of short messages is twofold: messages spread more quickly than on small-world or true-life short messages networks, but longevity of short message is less than the other networks. Some behaviors of mobile phone users obviously influence the process of short message spreading. Meanwhile, we found that the longevity of short message relate to network diameter.
