Abstract: Aiming at the problems that the trust model is simple and the energy consumption is not optimized enough in the existing trust-aware routing protocols. A secure clustering routing protocol based on trust and balancing energy consumption (SCR-TBE) is proposed. Introducing multiple evaluation factors, direct trust is calculated by fuzzy comprehensive evaluation model, and the recommendation trust is filtered and weighted allocation based on the deviation degree, and comprehensive trust is calculated added historical trust value. And the cluster head penalty coefficient is designed to speed up the identification and isolation of malicious cluster heads. By dividing the monitoring area, the unequal clustering is achieved to alleviate the energy hole phenomenon. The node trust value, dump energy and data transmission distance are chosen as routing factors. The cluster function and forwarding function are designed to reduce the chance of malicious nodes participating in data transmission. Simulation results show that, compared with LEACH-C and TLES protocols, both the number of data packets and the energy consumption balance have been greatly improved, enhancing the security and reliability of wireless sensor networks.
