Construction method of the link equation in viral mobile communication based on cross entropy

Aiming at broadband CDMA mobile communication system, we define a way which constructs the link equation of viral mobile communication network based on cross entropy. Through defining the call model of mobile users, this method constructs the link equation of viral mobile communication, introducing the conception of the cross entropy, simulates and analyzes the impact which is the handover probability of mobile users in microcell and the moving speed doing viral mobile communication on network performance. The result of simulation shows that the average moving speed of viral mobile users in microcell could reach 2.8 m/s. The analysis result supplies a method when apply the link equation of viral mobile communication based on cross entropy to 3G and 4G CDMA mobile communication system.
