摘　　要：针对移动对等(MP2P)网络的安全问题,提出一种MP2P网络安全拓扑构造协议(AMPSTP)。AMPSTP协议首先利用Fortune算法完成对地理区域的划分,然后给出临时锚节点的选取和更新策略、MP2P覆盖网拓扑模型的构造和维护机制、MP2P覆盖网的路由发现算法以及基于博弈的MP2P覆盖网的节点选择机制。最后对AMPSTP协议的性能进行理论分析和仿真实验。结果表明,与MADPastry协议相比AMPSTP协议不仅可以保障网络安全和提高网络性能,而且还大大降低了控制开销。For the security problem in mobile peer to peer（MP2P） networks,an adaptive mobile peer-to-peer secure topology protocol（AMPSTP） was proposed.Firstly,Fortune algorithm was used to divide a large geographical region into some small sub regions.Secondly,temporary anchor node selection and update strategies were given.Thirdly,MP2P overlay network topology construction and maintenance mechanisms were also given.Fourthly,MP2P overlay network routing discovery algorithm and node selection mechanism based on game theory for MP2P networks were successively proposed.Finally,the performance of the AMPSTP protocol was theoretically analyzed and simulated on the platform of NS-2.Theoretical analysis and simulation results show that compared with MADPastry protocol,AMPSTP protocol not only can guarantee the network security and improve network performance,but also greatly reduce the control overhead.
