[0002] With the rapid development of computer and network technologies, computer systems and network environments have become indispensable infrastructure in modern society. Dynamic network optimization of computer architectures has become particularly important in the field of autonomous driving. Autonomous vehicles rely on powerful computing power and efficient network communications to ensure driving safety and real-time decision-making. Existing network optimization methods primarily focus on static network configuration and bandwidth management, but these methods fail to fully consider factors such as the complex and ever-changing network conditions, vehicle speed variations, and road congestion encountered by autonomous vehicles during actual driving. Furthermore, traditional optimization algorithms often employ fixed resource allocation strategies that lack adaptability to real-time environmental data and the ability to dynamically adjust. This makes them inadequate in the face of rapidly changing network and traffic conditions.

[0003] To address the above issues, a computer-based network dynamic optimization method and system are proposed. This method aims to dynamically adjust the allocation of computing and network resources by real-time monitoring of the network status, vehicle speed, and road congestion of unmanned vehicles, thereby optimizing the driving performance and decision-making efficiency of unmanned vehicles. It can adaptively adjust resource allocation strategies based on real-time environmental data and mission requirements, enabling unmanned vehicles to achieve more efficient and intelligent driving decisions while ensuring safety.

[0040] At any monitoring point in time during the driving process of the unmanned vehicle, the vehicle's current environmental data is obtained. The environmental data includes network status data, vehicle speed data, and vehicle data on the observed road section. Network status data includes key indicators such as bandwidth, latency, and packet loss rate. These indicators reflect the current status of the vehicle's wireless communication network. The collection of network status data is crucial for evaluating and optimizing communications between the vehicle and the control center, other vehicles, and roadside infrastructure. Based on the obtained environmental data, network quality performance values, vehicle speed performance values, and road congestion values ​​are calculated. The purpose of this step is to convert the raw environmental data into quantitative indicators that can be used for decision-making. These indicators can accurately reflect the current network and traffic conditions faced by the unmanned vehicle. Through these quantitative performance values, the system can more accurately allocate resources and adjust task priorities, thereby optimizing the driving performance and decision-making efficiency of the unmanned vehicle.

At the same time, set the maximum number of iterations; Step 2: For any candidate coefficient combination, use the formula Calculate the fitness F of the candidate coefficient combination, where D represents the average processing delay of each task when the candidate coefficient combination is applied for resource allocation; R represents the resource utilization rate when the candidate coefficient combination is applied for resource allocation; ω1 and ω2 are weight coefficients. This formula indicates that the lower the average processing delay of each task and the higher the resource utilization rate for resource allocation, the better the performance of the candidate coefficient combination. Step 3: Select the candidate coefficient group with the highest current fitness as the elite individual for the current iteration; then apply the roulette wheel selection method to all candidate coefficient combinations excluding the elite individuals, and select the corresponding number of candidate coefficient combinations with the best fitness performance according to the preset selection ratio, and form the selected candidate coefficient combinations into the selection individual set; Step 4: Apply the preset crossover probability to perform a crossover operation on the candidate coefficient combinations in the selected individual set to generate a corresponding number of new candidate coefficient combinations, and form the obtained new candidate coefficient combinations into a crossover individual set; randomly select candidate coefficient combinations from the crossover individual set, and make small adjustments to the candidate coefficient combinations according to the preset mutation probability to obtain a mutation individual set; Step 5: Merge the selected individual set and the mutated individual set to obtain the merged individual set, calculate the fitness of all candidate coefficient combinations in the merged individual set, and use the x-1 candidate coefficient combinations with the best fitness performance in the merged individual set and the selected elite individuals as the new generation population; Step 6: Repeat steps 3 to 5 to iteratively update the population until the maximum number of iterations is reached, and use the candidate coefficient combination with the highest fitness in the last generation of the population as the adjustment coefficient combination k j .
