In this study, we present a highly practical marketing course. Through learning marketing, we can cultivate students' ability to analyze, solve and practice problems. Therefore, this paper would study the problems encountered in the marketing course through cloud computing technology and propose corresponding countermeasures, so as to better improve students' ability to analyze and solve problems and enhance the effectiveness of the classroom. This paper also analyzed the data aggregation algorithm based on Particle Swarm Optimization (PSO) algorithm. The results showed that when other conditions were the same, only 6 students approve of the traditional marketing teaching mode, accounting for 12%;there were 44 people who did not approve, accounting for 88%. This number was more than half;49 students recognized the optimized marketing teaching mode, accounting for 98%;there was 1 person who did not approve, accounting for 2%. The proportion of people who did not approve after optimization was far less than that of the traditional model, which showed that cloud computing data aggregation algorithm could find out the problems in marketing teaching and provide correct countermeasures to solve them, so that the teaching model could be optimized. (1) The data aggregation algorithm based on cloud computing has a good optimization effect on the evaluation of marketing teaching problems and countermeasures, indicating a new direction for future research. (2) The combination of cloud computing and data aggregation algorithm is not only a novel research perspective, but also a perfect idea. (3) Marketing course is a very important course in today's society. The study of its teaching problems and countermeasures evaluation will help students improve their learning efficiency and enhance their ability to adapt to the society.

Based on BD-AI(Big data Artificial Intelligence) technology, an efficient LB data collection algorithm was designed and implemented for experimental verification and performance evaluation. The results showed the average load of algorithms A and B tested five times was between 44-48 and 60-64, respectively;the algorithms A and C were tested five times with data transmission speeds between 10-11Mbps and 4-5Mbps, respectively. The LB data aggregation algorithm based on BD-AI in WSN is more efficient than traditional LB algorithms and traditional data aggregation algorithms. It can effectively help solve problems such as imbalanced data exchange, data redundancy, and energy waste among wireless sensor nodes, thereby improving the data collection efficiency and energy conservation of sensor networks, laying the foundation for implementing application scenarios such as intelligent perception and remote monitoring. The load balancing data aggregation algorithm of wireless sensor networks based on Big data artificial intelligence is faced with some challenges and difficulties. For example, wireless sensor networks usually produce a large amount of data, which needs real-time aggregation and processing;Nodes in wireless sensor networks typically have limited computing, storage, and communication resources, among other issues.

INTERNET OF THINGS 2024年 27卷

In IoT infrastructure, high-frequency sensing and subsequent transmission of sensed data to computational facilities can lead to redundant data storage and processing, consuming significant storage and processing capacity. As a result, the IoT infrastructure needs more data transmission cycles, leading to data redundancy and low network up-time due to the drainage of limited battery capacity. Conversely, if the data is communicated at a lower rate, it may cause absolute data delivery to the processing unit, which is useless. As a result, a well-designed data aggregation algorithm is required. This paper proposes the ADA2 2 - IoT, , an Adaptive data aggregation algorithm for IoT Infrastructure tailored to optimize parameters such as low data redundancy, limited data communication cycles, and high IoT infrastructure up times. The proposed algorithm consists of two key components: the Route data Aggregator (RDA) performs aggregation during data transit towards the Edge node or gateway, and the Node data Aggregator (NDA) performs data aggregation during capturing or sensing data. The algorithm employs metrics like Age of Information (AoI) and data freshness factor during the node and route data aggregation phase to capture and timely deliver data to the Edge node, where this data is processed for informed decision-making. The proposed algorithm was efficiently tested on a simulation and IoT hardware deployment environment. Both simulation and hardware results demonstrate a substantial improvement in QoS parameters, such as a decrease in data redundancy and packet exchanges, leading to considerable energy savings and prolonging the lifespan of IoT infrastructure.

The increased use of distributed energy resources and the emerging active distribution networks require new models for planning and operation of power systems. Microgrids paradigm proposes an optimal energy transfer using dedicated control algorithms and taking advantage from the ability to offer different levels of power quality. In order to achieve a real time control, a detailed model is required together with new algorithms for information retrieval. Although measurements are able to give insight to such details, the information has to be structured in a new way. Presently there are in use aggregation algorithms inherited from power quality standards like the IEC 61000-4-30 set. A discussion of the time-and space- (i.e. dual) aggregation is proposed in the paper, based on an analysis performed on local measurements in weak LV grid in Romania and MV grid with distributed generation. data delivered by PMUs with a reporting rate of 50 frames per second is processed to highlight the effect of aggregation algorithms.

data aggregation is an efficient method to decrease the energy consumption in wireless sensor networks. The structure based data aggregation algorithm is not suitable for the application of dynamic events, because the structured sensor network requires higher communication overheads to capture the event when the data sources are changing dynamically. We propose an energy efficient data aggregation algorithm utilized for dynamic event in wireless sensor networks. In this algorithm, the sensor nodes utilize the advantage of wireless channel that the energy consumption for broadcasting is approximately equivalent to that for sending to just one neighbor. data are aggregated among nodes by one time broadcasting. Geography based routing method is used in data aggregation and transmit the data to the remote sink node. Simulation results show that the proposed data aggregation algorithm can decrease the maximum and mean energy consumption of sensor nodes highly in dynamic events.

Power Quality indicators are still conveyed into a classical paradigm of power systems where the steady state operation is governed by quasi-constant frequency. Moreover, distribution grids are considered as network structures with solely load behavior. The standards proposing power quality descriptors are built on models, which seem to limit the possibilities of achieving real time control targeting highly efficient energy transfer, at least in all-electric grids. In this paper the measurement data aggregation algorithms proposed in the well-known standard IEC 61000-4-30 are discussed based on an analysis performed on voltages and frequency measurements. Raw data are obtained from PMUs installed in various nodes of active distribution grids with reporting rate of 50 frames per second. New aggregation algorithms for frequency, rate of change of frequency and unbalance coefficient appear to be needed.
