MEC Offloading Strategy Based on Data Compression in Blockchain
In order to solve the problem of low throughput of blockchain system,an offloading strategy based on data compression is proposed under the integration of blockchain network and mobile edge computing.The system computing delay is minimized by optimizing the offloading rates and compression rates under the two schemes of optimized and non-optimized computing resources,respectively.The auxiliary variables and relaxation variables are used to transform the non-convex problem and the existing tools are utilized to solve the unoptimized computing resources problem directly.An effective iterative algorithm is proposed to solve the transformed problem for optimized computing resource scheme.Matlab simulation results show that the proposed iterative algorithm has a faster convergence speed and higher accuracy,and the performance of optimized computing resources is better than that of unoptimized computing resources.Compared with other strategies,the strategy based on data compression can accelerate the computation speed more effectively and solve the problem of low throughput of the blockchain system.
