自组织网络是由形成动态拓扑的移动路由器组成的无线自配置网络。在这样的环境中，这些路由器(节点)的任何恶意行为都可能极大地危及安全路由。然而，仅仅检测恶意节点并不足以保证安全。需要确保的是，只有可信节点才能参与路由。本文提出了一种分布式动态信任评估方案，用于保证移动自组网和传感器网络中DSR路由的安全。每个节点根据自己的直接经验、推荐和先验知识周期性地计算对其他节点的信任。大量的仿真研究表明，与以往提出的大多数方案不同，该方案能够有效地适应快速变化的信任场景，并且信任收敛到节点的长期行为所揭示的值。该方案具有较强的抗合谋攻击能力，在由于节点移动性而导致丢包时，避免对节点进行惩罚
An ad hoc network is wireless, self-configuring network of mobile routers forming a dynamic topology. In such an environment, any malicious behavior by these routers (nodes) could greatly compromise secured routing. However, just detecting the malicious nodes is not enough to guarantee security. It should be ensured that, only trusted nodes take part in routing. In this paper, we propose a distributed dynamic trust evaluation scheme for securing DSR routing in mobile ad hoc and sensor networks. Each node periodically calculates trust for others based on its direct experience, recommendation and previous knowledge. Extensive simulation studies show that our scheme, unlike most of the previously proposed ones, efficiently adapt to fast changing trust scenario and the trust converges to values, revealed by long term behavior of the nodes. This scheme is resistant to ‘ collusion’ attack and is cautious not to punish nodes when packet is dropped due to ‘ node mobility’
