%X In the recent years, Mobile Ad-Hoc Wireless Networks (MANET) have played a key role in communication system. It is a self-configured and infrastructure-less network. It is used in different application areas like disaster recovery operations, hospitals and agricultural sectors. However, there are a lot of problems that limit the performances of this network for significantly achieving its roles in different areas. To overcome these problems, this paper enhances the performances of MANET in wireless communication system by adapting smart antenna in Ad-hoc On-Demand Distance Vector (AODV) routing protocol combining with multiple network interfaces. The improved new version AODV utilizing directional antenna and multiple network interface compared with Omni-directional antenna is evaluated based on simulations, which was done with the Network Simulator version two (NS2). Through this study, we found out that directional antennas integrating with multiple network interface throughput and end to end delays always outperform Omni-directional antennas in both random and grid scenarios for AODV routing protocol. In high communication paths and long communication distances also directional antennas have significant improvements in contrast to traditional Omni-directional antennas. Finally, we recommend that for increasing throughput and decreasing end to end delay utilizing directional antennas and multiple network interfaces in MANET technology improve the performances of the wireless communication system.
