From: TIHOO: An Enhanced Hybrid Routing Protocol in Vehicular Ad-hoc Networks
Routing overhead based on number of vehicles. The routing overhead values of TIHOO, F-ANT, and AODV for various numbers of vehicles. In TIHOO, broadcasting of route request control packets are prevented and the discovery is conducted in a controlled manner while running this phase in AODV algorithm causes increased system overhead. Also, F-ANT protocol imposes increased overhead on the system as a result of employing the ACO metaheuristic algorithm and storing the whole information of the entire colony. Therefore, TIHOO outperforms other protocols in terms of overhead produced
