# Blockchain-Based UAV-Assisted Mobile Edge Computing for Dual Game Resource Allocation
## 4 Analysis of Resource Allocation Experiments
### Blockchain Experiment
From the perspective of system resource utilization and task scheduling, although the blockchain introduces additional computational overhead (approximately 10% overhead), the experimental results, as shown in Figure 11, show that the overall performance of the system remains good. Without the blockchain, the system's server resource utilization is high, with an average resource utilization rate of 92%. However, with the blockchain, the resource utilization rate decreases slightly to 90%, but this does not significantly affect the operating efficiency of the system. At the same time, task latency increased after the introduction of the blockchain, but the increase was limited, with latency increasing from an average of 1.5 times to 2 times when the blockchain was not used. This shows that although the blockchain brings certain computational overheads and latency, its negative impact on the system is relatively small, and its improved security, especially in terms of data protection and identity authentication, more than makes up for these effects. Therefore, the blockchain not only effectively enhances the security of the system, but also maintains high resource utilization efficiency and task execution capabilities. Figure 10: Impact of blockchain on resource information. The above experiments systematically analyze the impact of blockchain technology on key aspects such as attack defense, data integrity and authentication, and resource utilization and task latency, and comprehensively evaluate the role of blockchain in improving system security and overall performance. First, in terms of attack defense, the distributed architecture of the blockchain significantly enhances the system's resistance to malicious attacks, especially against DDoS attacks and data tampering. Experimental results show that when blockchain is not used, the system is successfully invaded an average of 15 times in 50 simulated attacks, with a success rate of 30%, while after the introduction of blockchain, the number of successful attacks significantly reduced to 2.5 times, and the success rate of attacks is reduced to 5%, effectively improving the system's defense capabilities and reducing the risk of data breaches and service disruptions. In terms of data integrity and identity verification, blockchain ensures data integrity and the authenticity of user identity by leveraging its tamper-resistant data and decentralized verification mechanism. Experiments have shown that the blockchain-based identity verification solution reduces the risk of identity forgery and data tampering by 60%, and there has been no data inconsistency during multiple verification processes, which proves its high reliability in sensitive data protection and access control. In terms of resource utilization and task latency, although blockchain introduces additional computing and communication overheads (about 10%), the overall system performance remains at a high level, and there is no significant impact on task execution efficiency and resource consumption. The experimental results show that when blockchain is not used, the average resource utilization of the system is 92%, while after blockchain is introduced, the resource utilization rate decreases slightly to 90% due to the additional computing consumption, but it is still at a high level, indicating that blockchain has a limited impact on the system's computing resources. In addition, task latency increased after the introduction of blockchain, from an average of 1.5 times when blockchain was not used to 2 times, an increase of about 3%. However, the overall latency fluctuation range remained stable within a reasonable range, and did not significantly affect task scheduling efficiency. It is worth noting that although blockchain technology has brought about a slight increase in computing and time overheads, its improvement in data security and authentication reliability has more than compensated for the negative impact of these overheads on system performance.
