Attack Model Research on Node Localization Systems of Wireless Sensor Networks

Along with the profound development of wireless sensor network, and in the environment of complicated and full of counteract communication, correct localization information of node is the prerequisite and basis of accomplishing some modules, such as construction of sensor network, maintenance, incident localization, target tracking. Thus, localization security becomes a key technique. Mastering the merits of wireless sensor network attack is a vital prerequisite of solving security question. The paper mainly discusses attack module of localization system in WSN, and makes a specific research on attack theory, attack features, attack effect, etc. On the basis of the attack module analysis, the paper comes up with localization security demand.
