Trust management is an emerging security approach used to conduct nodes' relationships in mobile ad hoc networks. It relates to assigning a trust level to each network component based on its cooperative behavior with respect to system goals. Because of its infrastructure-less nature, frequent network dynamics, and severe resource constraints, it is complex to establish trust in such a network. Mainly, trust systems are vulnerable to attacks that make use of inherent properties of the trust model to alter the accuracy of estimated trust levels, referred to as trust-distortion attacks.Because of the contradictory nature of such attacks, their detection can be confusing, complex, and energy-demanding, especially in multiattack environments. To handle such threats, we propose a Green Trust-distortion Resistant Trust Management Scheme, called GTRTMS, which handles different trust-distortion attacks in multiattack environments. The proposed solution self-adapts its trust knowledge monitoring according to the network context to conserve the energy of mobile nodes and reduce the produced CO 2 emissions. Simulation results prove that GTRTMS exhibits significantly better performance than the other counterpart in presence of simultaneous and contradictory different trust-distortion attacks.KEYWORDS mobile ad hoc networks, trust-distortion attacks, trust management Int J Commun Syst. 2017;30:e3331.wileyonlinelibrary.com/journal/dac
