The aim of the model, which is analyzed by the mean field theory, is to optimize network structures based on users' behaviors in MANETs. The analysis results indicate that the network generated by this evolving model is a kind of scale-free network. This evolving model can improve the fault-tolerance performance of networks by balancing the connectivity and two factors, i.e., the remaining energy and the distance to nodes. The simulation results show that the evolving topology model has superior performance in reducing the traffic load and the energy consumption, prolonging network lifetime and improving the scalability of networks. It is an available approach for establishing and analyzing actual MANETs.展开更多

When studying initiative, even if encounter difficulties, will try hard to overcome which have the good mood. School physical education is the foundation of our socialist undertakings of physical culture and sports, sports teaching is an important part of school physical education. We firmly believe that through the reform according to the proposed methodology, the performance of the classes will be optimized.展开更多
