Patent ID: 7907888

Claim:
A mobile jamming attack method applied in a wireless sensor network having a plurality of sensor nodes, comprising steps of: (a) distributing a mobile jammer initiating a jamming attack to the wireless sensor network; (b) configuring a jamming threshold; (c) monitoring a network throughput of a sensor node adjacent to the mobile jammer, and learning a data flow direction of the sensor node; (d) determining if the network throughput of the sensor node is lower than the jamming threshold; (e) continuously moving the mobile jamming upstream along the data flow direction and re-executing step (c) if the network throughput has not reached the jamming threshold; and (f) otherwise, confirming if the sensor node is located on a critical path of a base station connected to the wireless sensor network, and initiating the attack on the sensor node and at least one sensor node on the neighborhood to generate a jammed area, so that the sensor nodes jammed in the jammed area and at least one affected sensor node in the downstream all fail to transmit data to the base station of the wireless sensor network.
