ABSTRACT

ln an ad-hoc network, routing protocols play an important role in providing packets with the minimum time from source to destination and in selecting the best path by using fever network resources between the nodes. The design of the routing protocol in any type of network is an important issue in the MANET. In modem years, attention to
MANET has developed due to the accessibility of wireless communication devices that provide services at all times and everywhere. This research is based on the simulation and detailed analysis of MANET routing protocols for DSDV (Destination Sequence Distance Vector), AODV (Ad-Hoc On Demand Distance Vector) and GAF (Geographic Adaptive Fidelity). These routing protocols are analyzed by the delay, throughput and delivery ratio of metric parameters. To analyze performance, two scenarios have been used, such as different scalability and different mobility speeds. The result analysis suggested the best choice of routing protocol in different scenarios.
