摘要
无线Mesh网络(WMN)的开放性、动态性等优点使它得到了广泛应用,同时也产生了一些安全问题,传统的信任模型无法满足WMN的安全需求。基于社会网络的信任原理,提出了一种新的WMN信任模型TFTrust。该模型定义了与信任相关的多维因子计算方法,包括节点贡献度、节点依赖度以及交互频繁度,构建了节点间直接信任值的计算方法。仿真结果表明:TFTrust模型在网络的安全性、服务质量及降低网络通信代价等方面均优于无线自组网按需平面距离向量路由(AODV)协议及Beth模型。
The openness and dynamics of Wireless Mesh Network (WMN) makes it used widely, however, there are some security problems. The traditional trust model could no longer meet the security requirements of WMN. Based on the trust principle of social network, a new trust model named TFTrust was proposed. In the TFTrust, multi-dimensional factor calculation method was defined, including node contribution value, node dependency value and interaction frequency value, also the calculation method of the direct trust value was established. The simulation results show that TFTrust model is better than Ad Hoc on-demand Distance Vector Routing (AODV) protocol and Beth model in safety, quality of service and reduces the cost of network communications, etc.
