基于快速移动节点的Ad hoc网络可信度模型及可信路由协议

Research on fasting-moving node assisted trust model and routing protocol in mobile Ad hoc networks

由于目前广泛应用的路由协议大都是假设网络中的节点是可以信任和相互协作的,对于安全的问题考虑不多,而网络中某些节点很容易被俘获而成为恶意节点,使得现有的路由协议变得十分脆弱,针对这一问题,提出了基于快速移动节点的可信度模型FATM,以及基于快速移动节点的可信路由协议FARP,通过网络中的快速移动节点辅助一般节点进行可信度的计算和更新,并在可信模型建立之后选择可信度较高的路由进行通信。最后采用OPNET对FATM模型进行了仿真,仿真结果表明基于快速移动节点的可信度模型的安全性更高,并且节省了一般节点的能量和空间开销,具有较好的网络适应性及可扩展性。

Current widely used routing protocols mostly assume the nodes in the network are cooperative and trustful, however, some nodes can easily be captured and become malicious node, making the routing protocols become weak, to design a secure routing protocol has become a serious problem. To solve this problem, This paper presents the reliability of FATM model based on fast moving nodes, and FARP based on trusted routing protocol, calculating and updating aided general node credibility by fast moving nodes in the network, and choosing high reliability communication routing after trusted model. Finally, OPNET is used in the simulation of the FATM model, the simulation results show that the security of the trust model based on fast moving nodes and trusted routing is higher, and saves energy and space than that on general nodes, and has better network adaptability and scalability.
