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.
Compared the short message spread in three kinds of networks, such as scale-free network, small-world network and actual short message network, and find out the factors that affect the spread of short message.The research found that both the network topology and mobile phone users’ Affect the process of short message propagation.The speed of short message propagation in scale-free network is faster than that of small-world network and actual short-message network, while the short-life of short message without scale network is short in the world network and the actual short-message network; The mobile phone users’ short message forwarding behavior obviously affected the process of short message transmission, and also found that the short message life span is related to the network diameter.
