Abstract

Wireless sensor networks (WSNs) are deployed in potentially hostile environments where enemies may be present, especially in the military. Since WSNs are mostly left without any notice since they are available in remote areas. Due to this unnoticed nature of wireless sensor networks, an attacker can easily capture and get access to the sensor nodes and replicate them, and then impose a variety of attacks with these replicas. These attacks are dangerous because they allow the attacker to extend the control over few nodes to much of the network. A fast and effective mobile replica node detection scheme using the localized multicast is proposed. Here, a scheme called P-MPC is used. The efficiency and security of this approach are evaluated theoretically. The results show that, compared to previous approaches proposed, this approach is more efficient in terms of communication and memory costs in large-scale sensor networks, and at the same time achieve a higher probability of detecting node replicas.
