Certain Investigation, Analysis and Design of Smart Antenna based Mobile Ad-Hoc Network using HFSS

Mobile Ad-hoc Networks (MANET) are wireless networks that enable direct or indirect communication between nodes without the need of a permanent infrastructure. Because of this, MANETs are crucial in a number of situations when a fixed infrastructure is unavailable, unreliable, costly, or unstable. Vehicle-to-vehicle communications, emergency services in crisis situations (earthquake, flood, or fire), tactical communications, and sensor networks are examples of typical uses. Because there is no one point of control, a self-organizing network operates in a dispersed fashion. Nodes are in charge of dynamically finding one another and communicating directly when they are in each other's transmit range. Intermediate nodes serve as routers that redirect packets created by other nodes to their destinations, enabling communication between nodes that are not immediately inside each other's transmit range. Additionally, as devices may freely enter and exit the network and move around at will, topological changes may happen quickly and unexpectedly, leading to link failure and the need for rerouting. Mobile nodes also have a wide variety of range capabilities and often operate on batteries, which results in energy limits. Many studies have been conducted to find ways to address these challenges. Smart antennas may improve network performance by enabling spatial channel reuse, extending the coverage area, and improving the quality of the received signal. Additionally, they may be used to lower power emissions, conserving battery power. Network adaptability and re-configurability are two enticing features of mobile ad hoc networks. A smart antenna in this situation that can self-configure numerous high-directivity beams offers a significant benefit in terms of power savings, greater range, and spatial channel reuse.
