An Effective Scheme for Defending Denial-of-Sleep Attack in Wireless Sensor Networks
Chen Chen, Hui Li, Qingqi Pei, Lv Ning, Qingquan Peng · 2009
Based on the analysis to the phenomenon and methods of denial-of-sleep attacking in wireless sensor network, a scheme is proposed employing fake schedule switch with RSSI measurement aid. The sensor nodes can reduce and weaken the harm from collision, exhaustion and broadcast attack and on the contrary make the attackers lose their energy quickly so as to die. Simulation results show that at a bit price of energy and delay, network health can be guaranteed and packets drop ratio has been decreased compare with original scenario without our scheme.
