Mobile ad hoc network relies on multi-point to complete routing tasks in collaboration

relationship of trust need to be established in the trusted routing between two nodes

but most of trust routing model only pursue the confidence of route whereas neglecting robustness.Basing on ANTHOCNET algorithm

the TrANTHOCNET algorithm is designed while taking into account both routing confidence and routing robustness.We introduce Fuzzy Petri Net formalized reasoning process algorithm to deal with the uncertain relationship among nodes

and use location information to update pheromone in real time which enhances routing robustness.The experiment results show that the TrANTHOCNET behaves better than ANTHOCNET

AODV and T-AODV when facing malicious nodes

it also has been proved effectively in routing performance.
