Communication in ad hoc network, such as Wireless Sensor Net- works (WSN), needs the use of decentralised routing algorithms requiring that several sensors behave in an expected way. This introduces a vulnera- bility as the global issue of decentralized tasks depends on local behaviors and is compromised in case of failures or malicious intrusions. We propose here an adaptation of a routing protocol for WSN, the MWAC model, that introduces trust decisions to detect and avoid sensors that exhibit an incor- rect behavior. The proposed trusted routing algorithms takes into account the low energy, communication and memory capacity of sensors to provide a realistic improvement of the routing robustness.
