For the secure two-way communication and forwarding, this paper proposes SRDA, a secure routing and data aggregation approach for wireless smart meter. This approach introduces the unique wireless smart meter identifier to represent its public identity information, and gives a secure routing architecture based on control and forwarding separation. In this architecture, SRDA uses the proxy re-encryption data aggregation algorithm to protect security of data transmission. By using the routing algorithm according to distance and link quality, SRDA achieves the best routing path and provides several alternative paths which have different priorities. Besides, the identifier-based cryptography mechanism is used to issue and update the routing information in security, and the proxy re-encryption mechanism is designed to preserve the data privacy. In conclusion, this paper gives an analysis for the relatively excellent security, scalability and energy efficiency. © 2016 Journal of Communications.

Software Defined Networking (SDN) is a new type of network architecture, which provides an important way to implement automated network deployment and flexible management. However, security problems in SDN are also inevitable. DDoS attack belongs to one of the most serious attack types, which is fairly common for today’s Internet. In SDN security fields, DDoS attack detection research has been received more and more attention. In this paper, a DDoS attack detection method based on one-class SVM in SDN is proposed, which provides a better detection accuracy. Furthermore, two new feature vectors, including middle value of flow table item’s duration and protocol data traffic percentage, are extracted to integrate into the item of 11 feature vectors. Additionally, basing on selection and construction method of the 11 feature vectors, a DDoS attack behavior model is established by using one-class SVM algorithm, and the self-adaptation genetic algorithm is designed to optimize the corresponding parameters of the Gaussian kernel of one-class SVM. The experimental results in SDN show that, the proposed new feature vectors are shown to more better detection accuracy, and the proposed method is more feasible by comparing with the BP neural network and RBF neural network algorithms under the same 11 features vectors. © Springer Nature Singapore Pte Ltd 2020.

Steam generator is the key equipment in the large and complex nuclear power plant, and its water supply system has the characteristics of time-varying, large delay, nonlinear. In this paper, a segmented linearized model based on wavelet neural network is developed for a steam generator feedwater system of a nuclear power plant. All the data of the automation stages of the steam generator, which are steam flow rate, feedwater flow rate and liquid level from 20% load to 100% load, are collected and divided into six stages based on the characteristics of the data. For the first four stages of data, the feedwater system was modelled using the Hammerstein-Wiener method based on wavelet neural network, which was used as the nonlinear input and nonlinear output module of Hammerstein-Wiener. And for the remaining two stages of data, the nonlinear autoregressive models based on with exogenous (ARX) inputs model approach was modelled using nonlinear ARX as the underlying framework of wavelet neural network. The proposed model can be used for model predictive control to switch between different models based on load changes. Through the verification of simulation experiments, the built model can accurately reflect the trend of actual data, and the predicted values have high accuracy and reliability. © The Institution of Engineering & Technology 2024.

As the traditional aluminum reduction cell energy efficiency analysis method is not comprehensive, this paper considers the impact of energy, materials and status of cells on the efficiency, and presents a new energy efficiency evaluation method of aluminum reduction cell based on the fuzzy competition-cooperation Data Envelopment Analysis cross-efficiency evaluation model. The paper first selects Al2O3 mass, Al F3 mass, anode movement, the average cell voltage and the cell age as the input indexes of the model, and the actual amount of molten aluminum as the output index;then in order to further explore the relationship among the decision making units, the fuzzy competition-cooperation DEA cross-efficiency evaluation model is proposed instead of the traditional DEA model;at last, the new model is adopted to evaluate the efficiency of the aluminum reduction cells with the real field data.

The velocity of agricultural vehicle is an important variable for the navigation system and variable rate applicator in precision agriculture, and the stable velocity in the filed improves the control accuracy of those systems. After analyzed the powertrain system of agricultural vehicles, a simple and general velocity control system was designed regardless of the structure of powertrain. Meanwhile, this system can be adapted without damage the vehicle's original mechanical structure, and cooperate with the precision agriculture application via the CAN bus. The variable universe method and incomplete derivation control strategy were introduced in the designed of fuzzy-PD controller to improve the adaptability. The road test was accomplished on LOVOL TA800 tractor and YAMMAR VP6 rice transplanter. The test results show that the mean absolute error is less than 0.045 m/s, and the velocity control system is reliable and effective.

Scheduling workflows in hybrid cloud environments presents significant challenges due to the inherent complexity of workflows and the dynamic nature of cloud resources. This complexity is further increased when attempting to balance workflow performance with privacy protection. Recent efforts have leveraged deep reinforcement learning (DRL) to address these challenges. However, most of these approaches rely on single-agent models, which can lead to security issues and scalability problems due to their centralized processing. Specifically, the properties of workflows are transferred to the single agent, which risks leaking privacy information. Our paper addresses these issues by introducing MARS, a real-time workflow scheduling method that prioritizes privacy protection in hybrid clouds. MARS leverages multi-agent deep reinforcement learning (MADRL) to optimize the workflow scheduling of cloud virtual machines (VMs). The benefit of our solution is that it relies on the collaborative learning of multi-agents on multiple VMs, which could assign user data to specific cloud servers for privacy protection while sharing training experiences between agents. In our implementation, MARS aims to reduce workflow completion time and operational costs while complying with strict privacy protection guidelines. The experimental results demonstrate that MARS can significantly surpass existing methods, reducing makespan by an average of 53.18% and costs by 61.98% compared to basic techniques, and achieving 20.26% and 25.71% improvements over the latest advanced methods, respectively. © 2024 IEEE.

The protocol Powerlink which is one of real-time Ethernet protocols included in the Standard IEC FDIS61784-2, has been widely used for the communication of both IO devices in industrial fields and drives for motor control applications to provide deterministic data transmission. When the Powerlink network is running in the industrial field environment, the online measurement of time related indicators is an appropriate method to evaluate the performance of the network in real time and detect communication faults between devices. In this paper, several time related indicators are proposed and analyzed to estimate the real time performance of the network when all devices get into the operate state. Further more, an efficient method to measure the proposed indicators based on frame analysis is presented and implemented on a PC-based monitor station that stores all the frames which transfer in the network and contain timestamp added by an FPGA-based probe. The measurement method is tested on a real network consisting of one master node and two slave nodes, and some experimental results are presented.
