Abstract
The two most essential factors for mobile self-organizing networks applicable to drones are reliability and stability. In harsh communication environments, such as mountainous regions and natural disasters, the use of satellites and terrestrial communication stations has severe time delays due to the high speed of UAVs, resulting in frequent communication interruptions with UAVs. Therefore, UAVs need to establish self-organizing networks for communication and information sharing. High-speed movement will lead to rapid changes in the network topology, resulting in established links being in an unstable connection state and even frequent routing errors, thus preventing the establishment of stable communication links. In order to improve the communication quality of UAVs under high-speed movement, we propose a dynamic source routing protocol based on path reliability and monitoring repair mechanism (DSR-PM). The model performs data transmission by filtering the best reliability path. The link state information is monitored during transmission and broken links are repaired in time to ensure the communication stability and reliability of the links and improve the data transmission efficiency. We simulated the approach in NS2 software and the simulation results show that the DSR-PM protocol effectively reduces parameters such as overhead, packet loss and delay, improves network throughput, and provides better communication performance.

With the development of communication technology, the current technical standards related to 5G communication have been basically completed and 5G has been commercialized in some countries and regions [1,2]
When a source node s produces a new data packet that needs to be transmitted to a destination node d, the source node s will add to a source route in the header of the data group, so that the source routing data is transmitted to the node of the destination [19]
After the intermediate node receives the routing request, it is divided by the source node and the target node’s id and its information in the request packet, which can divide into the following situations: 1. If this node is the target node for this route, the node will send a "route response", which is collected by the reply bag from the response bag, which contains the resulting routing record, and the initiator node receives the message from the response package, and stores the information in the packet in its own routing memory for subsequent communication
Summary
With the development of communication technology, the current technical standards related to 5G communication have been basically completed and 5G has been commercialized in some countries and regions [1,2]. Thillaikarasi proposed an effective DSR protocol for detecting black hole attacks in wireless sensor networks [9] This method effectively stops the black hole attack by detecting malicious nodes in the network, improves the security of communication and ensures the transmission of information. Since mobile self-organizing networks are vulnerable to various attacks, malicious nodes occupy processor threads and memory space by sending multiple packets, preventing these nodes from receiving redundant data and information This approach effectively identifies and detects malicious nodes, applies a reasonable node penalty system, and reconsiders node usage to ensure that each node is in the correct working state and improves the communication security of the protocol. Mythili proposed a new secure routing mechanism, the spatial and energy-aware trusted dynamic distance DSR algorithm, for improving the survival time of wireless sensor networks [14].
