Since sensors may be deployed in hostile environments for many large-scale wireless sensor network (WSN) applications, they are vulnerable to physical attacks. In a replication attack, which is considered to be a cost-effective physical attack, after capturing at least one sensor node, an adversary clones several nodes and surreptitiously returns replicas(More)
This paper addresses a new control strategy for synchronizing two or more distributed and interconnected dynamic systems having communication time delays. The proposed strategy that uses the Smith predictor principle and delay information not only achieves synchronization but also preserves the natural local dynamics of each subsystem without being affected(More)
To detect replica nodes in a wireless sensor network, we propose a distributed, deterministic and resilient (DDR) replica detection protocol developed from a witness node based strategy. In DDR, while a location claim message of each node is sent towards the designated verification location in the network, the consistency of the messages is verified at(More)
This paper proposes a generalized version of control strategy that enables state synchronization among distributed subsystems without altering the natural dynamics that each separate system is supposed to show. To handle the general case of N-subsystem with heterogeneous dynamics, a method of dynamic scaling and ring type network topology are proposed. The(More)
