Abstract: The research introduces a novel secure routing protocol for wireless sensor networks by integrating a trust model. The protocol incorporates acceleration factors and penalty coefficients to enhance the trust mechanism, enabling faster identification of malicious nodes and swift reduction of their trust values. The protocol introduces the acceleration factor and penalty factor into the trust mechanism to increase its response speed and trust value drop rate. Performance tests reveal that the protocol exhibits over 60% faster trust value reduction speed than TLEACH and 37% faster than the TLES protocol under black hole attacks. Additionally, the protocol demonstrates a longer life cycle, with the first node expiring around round 422 and half of the nodes ceasing operation by round 537, surpassing the longevity of TLEACH and TLES. These findings highlight the protocol's promising practical application potential.
