Abstract—Mobile Ad Hoc Networks (MANETs) are selforganizing, wireless networks devoid of any infrastructure in which mobile nodes can form connections and transmit messages cooperatively. Their adaptive nature and ability to self-configure makes them a viable solution in an Internet of Things (IoT) environment, while node mobility does impose some challenges in terms of route stability, packet loss, and energy wastage. This study examines how two different mobility models affect the performance of the Ad-Hoc on- Demand Distance Vector (AODV) routing protocol in the NetSim environment version 14.2. The effect of using two different speeds (10 m/s and 50 m/s) for both models and the AODV routing protocol were put to the test by observing five QoS (quality of service) metrics: Throughput, end-toend delay, Packet Delivery Ratio (PDR), routing overhead, and energy consumption. From the simulation results, it is concluded that node mobility will have a major affect routing behavior and energy use. Overall, the random waypoint mobility model provides the highest throughput and PDR along with moderate delay and energy consumption, as compared to random walk and no-mobility solutions. All mobility models (including no-mobility) exhibited degraded performance at 50 m/s due to excessive link breakage; however random waypoint provided the most overall balance in performance. In summary, these findings show that moderate, structured node mobility will enhance route stability, and the overall transport protocol performance for MANETs. These findings add value to potential designs for mobile network optimization in the future IoT.
