Flying Ad Hoc Networks (FANETs) need a set of parameters that are specific to the application. One of these parameters is energy, which must be measured regularly for as long as Flying ad hoc network exists. Most routing protocols, especially on-demand routing protocols like Dynamic Source Routing (DSR), mostly focus on finding the route with the shortest number of hop count. This leaves problems like delay and power management unsolved. In this research, we propose a novel high-priority transmission-based Energy saving Mechanism (HPSM) approach for flying ad hoc networks, which is an enhancement of the existing normal DSDV and DSR routing protocols. The UAVs are lightweight and heavyweight devices, and their use completely depends on the purpose. The UAVs are battery-powered devices, and we can use these devices for sort communication and by using multiple UAVs, transfer the data from one UAV to other UAVs. The main goal behind the development of the proposed HPSM is to reduce energy consumption and provide important information with high priority. In the proposed HPSM scheme, after route establishment, assign priority to senders based on their previous transmissions. If the UAVs have lost their energy or their energy is below then the threshold value, it means there is no need to establish the connection The performance of HPSM, DSDV, and DSR is measured by using performance matrices. The simulation is done in the NS-2 simulator, and the simulation results show that the performance of the proposed HPSM protocol is much better than that of the DSDV and DSR routing protocols. The proposed HPSM protocol enhances network performance by allowing a greater number of packets to be sent and received in the network.
