基于BFGS算法,建立了中国茶叶出口量与俄罗斯茶叶进口量之间关系的数学预测模型,将模型预测数据与真实数据进行对比,发现该算法收敛速度快、稳定性强,预测结果准确.

In this paper,we model the interaction of nodes in WSN and intrusion detection system(IDS) as a Bayesian game formulation and use this idea to make a secure routing protocol.As this game approaches to Nash equilibrium,it leads to a defense strategy for the network.Simulation results show that the model can availably repress the selfish behavior of nodes and raise the service quality of the network.
