摘要
PURPOSE: A wireless sensor network system capable of attack detection and an attack detection method for link quality indication-based routing on a wireless sensor network is provided to detect an attack in the attempt process of a sink hole attack. CONSTITUTION: An arbitrary receive sensor node receives a routing request packet from an arbitrary transmit sensor node(S1010). A minimum link quality indicator value(LQIMin) is extracted from the minimum link quality indicator value table of the receive sensor node between neighbor sensor nodes(S1020). The minimum link quality indicator value is compared with the minimum link quality indicator value(LQICur) of the routing request packet from the transmit sensor node(S1030). In case the LQICurLQIMin x C(C:allowable error rate) is accomplished, it is determined that an attack by a sink hole node is generated in a packet transmission path within a wireless sensor network(S1040). A new optimal path is re-searched(S1050).
