Algorithm 2
Hybrid trust calculation.
| Input DIS, TV, HTthre | | Output HT | | if vehicle i receives interactive information from vehicle j then | | Use Algorithm 1 to solve the ST and RT of the vehicle | | if Vehicle i is within the coverage of RSU then | | Calculate DCij using equation (8) | | Calculate using equation (9) | | Calculate IT using equation (10) | | else | | IT = 0 | | end if | | Calculate HT using equation (11) | | end if | | if HT ≥ HTthre then | | Confirm that vehicle j is a trusted vehicle | | Continue to receive interactive information from vehicle j | | else | | Confirm that vehicle j is a dishonest vehicle | | Discard the interaction request information of the vehicle | | end if | | Upgrade the trust management information of vehicle j in the LTD of vehicle i | | Broadcast the trust management upgrade information of vehicle i |
