中文摘要： 针对异构无线网络中物理层日益突出的通信安全问题，本项目拟从物理层角度研究异构无线网络安全机制。对无线节点在异构网络环境下的协同行为、资源分配和干扰协同进行深入分析，构建基于节点协同的异构无线网络物理层安全模型，利用不完全信息博弈和信息控制的理论对该模型进行改进。探讨不完全信息动态网络环境下各博弈主体动态偏好、学习与决策机制，采用动态演化博弈思想和跨层优化方法对动态路由选择、资源分配和干扰协同进行联合优化。提出不完全信息下，面向异构网络安全的物理层资源分配和干扰协同联合优化方法，自动适应网络环境动态变化，在源与目的节点间形成相对稳定的安全通信链路。本项目的完成有望为有效改善异构无线网络信息安全提供一条新的途径和方法，它将推动异构无线网络在通信中更加广泛的应用。锻炼和培养民族地区通信技术研究者，凝聚优秀人才，促进武陵山区通信技术发展。

英文摘要： In order to solve the increasingly outstanding problem about communication security for heterogeneous wireless networks,our research focus on physical layer security in heterogeneous wirless networks. We analyse wireless nodes'cooperative behaviors, resource allocation and cooperative jamming(collaborative jamming) in single network, homogeneous network or heterogeneous networks. Then the physical layer based heterogeneous wireless network security model will be proposed, based on wireless node cooperative behaviors. By using incomplete information game theory and information control theory, the security model is changed into a incomplete information game. In order to study heterogeneous wireless networks with dynamic topology character under incomplete information, we need analyse the self-adaptive behaviors of game subject and explore the preferences, learning and decision-making mechanism in heterogeneous wireless networks. By using dynamic evolution game theory and cross-layer optimization the idea of cross-layer design, we will propose to jointly optimize the danamic cooperative routing selection, resource allocation and cooperative jamming for physical layer security on this basis, which combines a dynamic evolution game model (DEGM) under incomplete information. Based on this model, a resource management and cooperative jamming method is proposed to jointly optimize the physical layer security performance of heterogeneous wireless networks under incomplete information, which can well suited to dynamic network environments and establish a relatively stable security communication link between the source and the destination. A new way and method can be proposed to effectively improve heterogeneous wirless networks information security accomplishing our research. It can also promote heterogeneous wirless networks to be applied in a more extensive area in communications.Furthermore, it is favorable to the exercise and cultivation of the communication and technology researcher and attract the talents and teams to strengthen in Wu-ling Mountain minority area.
