Abstract This paper discusses the setting of transceiver based on functional programming, and decouples the differences between communication protocol and network transmission protocol from the specific business implementation. In the actual application, the service implementation is set up. When the communication protocol changes, the function can be realized only by modifying the communication protocol, which improves the readability of the program and reduces its maintenance overhead

Set Up

EMTDC is grid simulation analysis software that is capable of modeling for complex electrical and electronic devices, controllers and non-linear network. PSCAD is a user graphical interface of EMTDC. In PSCAD environment, functional modules can be taken from the element library conveniently to set up a complete set of LV SVG control system for simulation study of operation performances under various work conditions. However, the control program of LV SVG in actual application is written in C language, which has great differences from some functional modules in PSCAD simulation module in terms of data processing approach and calculation precision, so there is a huge gap from the simulation result and the actual result.In this paper, Fortran language is used to write interface function. Control program written in C language is embedded into the simulation module set up by EMTDC. An experiment shows that the simulation model built by EMTDC and C language mixed programming has higher precision than ordinary simulation module, and can be transplanted among LV SVG controllers, so it’s more practical.

This paper investigates an average secrecy rate (ASR) maximization problem for an unmanned aerial vehicle (UAV) enabled wireless communication system, wherein a UAV is employed to deliver confidential information to a ground destination in the presence of a terrestrial passive eavesdropper. By employing an artificial noise (AN) injection based secure two-phase transmission protocol, we aim at jointly optimizing the UAV’s trajectory, network transmission power, and AN power allocation over a given time horizon to enhance the ASR performance. Specifically, we divide the original non-convex problem into four subproblems, and propose a successive convex approximation based efficient iterative algorithm to solve it suboptimally with guaranteed convergence. Simulation results demonstrate significant security advantages of our designed scheme over other known benchmarks, particularly for stringent flight durations.

Aiming at the problems of low protection accuracy and long time consumption in traditional privacy data protection methods, a privacy data protection method based on trusted computing and blockchain is proposed. Set up the Internet node secure transmission protocol through the trusted node uplink transmission protocol and the downlink transmission protocol, and according to the transmission protocol, combined with the blockchain technology, the ECC elliptic curve encryption algorithm is used to encrypt the amount of data existing in the blockchain, and the AES symmetric encryption algorithm is used to encrypt the private data that exists in the nonblockchain, thereby completing the protection of network private data. The simulation experiment results show that the privacy data protection accuracy of the proposed method is higher and the work efficiency is faster.
