Detection and Defense Technology of Blackhole Attacks in Wireless Sensor Network

摘要

The blackhole attack is a typical kind of attack in wireless sensor network (WSN), consisting two types, namely passive attacks and active attacks, of which the latter can cause greater threat. In this paper, considering the principles and characteristics of the active blackhole attacks, an effective approach that can detect and defense active blackhole attacks is presented by improving the AODV routing protocol combining flow analysis. NS2 simulation results confirm the effectiveness of this method.
