Location Similarity based Replica Node Detection for Sensor Networks

The node replica attack is known to be dangerous to wireless sensor networks (WSNs) because it enables the adversary to extend the damage throughout the network with very low cost. To stop such attack, we propose a similarity estimation based scheme with group deployment knowledge. Compared with prior works, our proposal provides extra functionality that prevent replica from generating false location claims. Through simulation experiment, we evaluate the performance of the proposed scheme and demonstrate that our scheme achieves effectiveness and efficiency under different situations and attack strategies.
