Ad-hoc On Demand Distance Vector (AODV) Performance Enhancement with Active Route Time-Out parameter

The routing protocols play an important role in the performance of the Ad-hoc mobile networks. The Ad-hoc On-Demand Distance Vector Routing Protocol (AODV) is a reactive routing protocol for mobile networks. The route discovery process in AODV is initiated only prior to link establishment for data communication. This research focuses on the effect of the Route states hold time parameter on the performance of the Ad-hoc mobile network which is indicated by the Packet Delivery Rate (PDR). Our aim is to identify the effect of varying Route states hold time parameters for Ad-hoc On Demand Distance Vector (AODV) and measure the degree at which the number of stations and their movement speeds affects the PDR. These factors are presented, discussed and simulated using OPNET simulation software. Key-Words: Aodv, Opnet, Olsr, Rreq, Rrep, Active route timeout (ART), Packet delivery rate (PDR)
