Wireless communication is significantly influenced by the Mobile Ad Hoc Network (MANET), which
consists of nodes like mobile phones, tablets, computers, or other devices that can connect with one
another. MANET is a decentralized network that communicates without using any specified infrastructure.
The lack of battery power in this multihop network with no infrastructure is problematic. As a result,
proper transmission power utilization must be considered. Transmission power significantly impacts the
data dissemination of different routing protocols used in this MANET environment. By taking this issue into
account, the performance of routing protocols is examined based on different transmission power settings.
The packet delivery ratio (PDR), packet loss (PL), jitter, and Dealy all play a role in determining network
service quality. This study investigates how transmission power impacts MANET routing protocols’ quality
of Service (QoS). The MANET routing protocols investigated in this study include AODV, OLSR, DSDV,
and DSR. NS3 is used to create the simulation environment. According to this analysis, AODV outperforms
other routing protocols in overall performance.
