摘要: 针对无线Ad Hoc网络中虚假推荐对信任度准确性造成的恶意影响的问题,提出了一种基于拓扑变换的信任度估计模型.分析与仿真结果表明,该模型的全局信任度具有迭代收敛性,加载此抵御虚假推荐的信任模型能更有效地激励节点协作,分组成功接收率和平均丢包数都有一定改善,同时更适合较大规模的网络.

Abstract:  In term of the influence of fake recommendation on the accuracy of recommendation trust in wireless Ad Hoc networks, a trust model based on topology transformation was proposed. Mathematic analyses and simulations results reveal that the proposed trust model has convergence characteristic, the fake recommendation-resisted model performs better in terms of packet successful delivery ratio and mean number of packets dropped. Meanwhile, this enhanced trusted model is more suitable for large scale networks.

Key words: topology transformation, trust model, mobile Ad Hoc networks
