The essential uncertainty in a wireless mobile ad hoc network (MANET), due to dynamic topology and limited resources, frequently makes communication links unstable. Thus, reliable and efficient routing protocol becomes a research hotspot of MANET. Ad hoc On-Demand Distance Vector Routing (AODV) protocol is currently one of the leading protocols for routing in MANET. In AODV, numerous control messages are used to construct and maintain a reliable route. However, these messages consume a large quantity of the network resources, and thus the effectiveness of AODV is reduced. In this paper, Fuzzy Velocity-based AODV (FV-AODV) is proposed for improving the reliability and the effectiveness of AODV in MANET. According to the velocities of the nodes, FV-AODV adaptively adjusts the HELLO_INTERVAL, which is the transmission time interval of HELLO message, to improve the reliability and the effectiveness of AODV. The performance of FV-AODV is evaluated in terms of control overhead, the number of HELLO messages, and delivery ratio. Simulation results demonstrate that FV-AODV achieves a better trade-off between the reliability and the effectiveness than AODV.
