Abstract
Industrial wireless sensor network is a new application of wireless sensor network in the field of industry in recent years. However, IWSN may be subject to different attacks and security risks, among which the Sybil attack is the most harmful type of base attack. According to the characteristics of wireless sensor networks in industrial environment, a new three-tier detection scheme is proposed. In the first-level, all common nodes and Sybil nodes were detected by RSSI-based quadratic difference method. In the second layer, the residual energy-based method is used to continue the detection of the nodes that have been detected in the first-level. The detection of first and second-level high-energy nodes is finally completed by the base station. The simulation results show that our proposed scheme significantly improves network lifetime and effectively improve the detection rate of Sybil nodes.
Highlights
Wireless sensor network (WSN) is a self-organizing distributed network system, which composed of a large number of tiny sensor nodes with wireless communication and computing capabilities [1]
We have solved the network problems caused by the conditions of network nodes, in the actual use process, IWSN often suffers from different attacks and security threats, such as Wormhole attack, Hello flood, Sinkhole and Sybil attack
We propose a detection scheme based on residual energy, to further detect the Sybil attack node sneaked through the first-order high-energy nodes
Summary
Wireless sensor network (WSN) is a self-organizing distributed network system, which composed of a large number of tiny sensor nodes with wireless communication and computing capabilities [1]. How to save energy and extend the survival time of the network has become the primary consideration To solve this problem, a heterogeneous IWSN is proposed, especially IWSN based on energy heterogeneous. In [5], it proposed that wireless sensor networks could use voting for a number of tasks. Previous studies did not consider how to detect in the energy heterogeneous IWSN On the contrary, they only considered how to detect Sybil nodes in the heterogeneous network.
