Effects on lifetime of opportunistic network based on Epidemic routing under flooding attacks

Abstract

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.
