A Trust-based Dynamic Slicing Mechanism for Wireless Sensor Networks

Abstract

Abstract The security of data is an important research challenge in Wireless Sensor Networks (WSNs), and the Secure Data Aggregation (SDA) provide a feasible solution to prevent the networks from being compromised. In this paper, we propose a Trust-based Dynamic Slicing Mechanism (TDSM) to improve the performance of WSN. By establishing a trust evaluation mechanism, TDSM calculates the trust value of each node in the corresponding time interval, and according to this trust value, we carry out Cluster Head (CH) selection and prevent the untrusted node from being selected as a CH. Meanwhile, a slicing scheme is discussed and the sensing data are divided into different slices according to the trust of node. The simulation results show that TDSM can defend against various attacks and promote the performance of WSNs.
