MANET路由协议的设计基于这样的假设，即所有节点在没有恶意破坏路由协议的操作的情况下进行合作。大量不同严重程度的攻击类型正在威胁着MANET。动态源路由（DSR）是一个著名的反应式MANET路由协议，不支持路由消息的安全性。本文研究了DSR及其流状态扩展路由协议在黑洞、灰洞、自私和泛洪攻击下的性能。我们的结论是，在所有攻击的存在下，流状态DSR的性能优于DSR。洪水攻击被发现会严重影响所有标准的性能指标。在静态网络中，使用未修改的DSR，黑洞攻击会显著降低数据包的投递率。所有的攻击都大大增加了端到端的延迟，这种影响在静态网络中尤其明显。
MANET routing protocols are designed based on the assumption that all nodes cooperate without maliciously disrupting the operation of the routing protocol. A large number of attack types of varying severity are threatening MANET. Dynamic Source Routing (DSR) is a well-known reactive MANET routing protocol that does not support security of routing messages. In this paper, we study the performance of both DSR and its flow-state extension routing protocols in the presence of blackhole, grayhole, selfish and flooding attacks. We conclude that the performance of flow-state DSR is better than DSR in the presence of all attacks. Flooding attacks are found to dramatically impact all the standard performance metrics. Blackhole attacks significantly worse the packet delivery ratio in a static network using unmodified DSR. All the attacks greatly increase the end-to-end delay; an effect particularly marked in a static network.
