中文摘要：

机会网络应用中存在能量无法补充的场景,泛洪是机会网络中容易发生的攻击行为。从理论上分析了在Epidemic路由机制下,泛洪攻击导致的节点能量消耗以及对网络生命期的影响。分析表明恶意节点数量的增加会对网络生命期产生显著影响,而恶意节点注入的数据分组的数量仅能在特定的场景下产生影响,且影响轻微。使用ONE仿真平台对泛洪攻击进行了仿真实验,仿真结果与理论分析的结论一致。

英文摘要：

In some scenarios of opportunistic network,energy could not be replenished.It was prone to flooding attacks in opportunistic network.The energy consumption of nodes and the effect on the network lifetime caused by flooding at-tacks under the mechanism of the Epidemic routing was analyzed.The analysis showed that the increase of malicious nodes had significant effects on network lifetime,and the number of packets from malicious nodes can only had effects in particular scenarios,and had minimal effects.ONE to simulate flooding attacks was used,the simulation results are same as the theoretical analysis.
