Introduction
With the progress of the times, the reform of higher education [1][2][3] is imperative. Engineering certification is carried out in conjunction with the educational improvement of colleges and universities.
is process includes the background of engineering certification, the specific process of college engineering majors and engineering certification [4][5][6], and the training plan for college engineering students. e purpose of engineering certification is to comprehensively evaluate the teaching management of college teachers, the faculty of teachers, and teaching equipment. Online education refers to the dissemination of knowledge and learning through the Internet and Applied Information Technology. erefore, engineering certification is a broader concept than online education. In this context, the curriculum reform of online education [7][8][9] has been pushed to the cusp of teaching reform. e emergence of online courses has provided great convenience for the sharing of teaching resources in different regions. Nowadays, excellent online open courses can be seen on the teaching platforms of various schools [10][11][12]. Online open courses provide students with low learning efficiency with multiple learning opportunities and to a certain extent, draw the distance between top students and students with average academic performance. Although online education has great convenience and various advantages, its disadvantages still exist. How to make the teaching mode of online education more flexible and the supervision system of the teaching mechanism more perfect, and to further improve the teaching effect of students are the problems that need to be solved now.
rough a lot of research, some effective methods have been discovered. Palvia et al. [13] pointed out the wide application of information and communication technology, the Internet and some information fusion technologies, and various modes of online education are growing rapidly and steadily all over the world. ey believed that this online education model will become an inseparable part of the education industry in the new world soon. Villegas-Ch et al. [14] proposed to combine data analysis techniques with artificial intelligence (AI) technology to improve students' learning. is method is on a stable education model, using online education as a platform, and trying to let virtual assistants help students. e proposal of this method has changed the way of communication and interaction between teachers and students to a certain extent. Chakraborty et al. [15] have shown that the teaching quality of physical classrooms is better than that of online education. However, as coronavirus disease-19 (COVID-19) is raging around the world, various schools are conducting online education, and students are very interested in learning materials and software for online education. Chen et al. [16] compared the results of online learning and traditional classroom accounting courses. Research results show that online classrooms can also provide better learning results. Liu et al. [17] studied the impact of online continuing dental education under coronavirus disease 2019 .
e results show that during the COVID-19 epidemic, China's online dental continuing education has increased significantly. Danchikov et al. [18] studied the potential of online learning under modern conditions and its application at different levels of education and explored the potential of online learning under modern conditions. e results show that under current conditions, the existing resources of educational institutions can effectively transform offline education into online education. Nevertheless, this closed education does affect the normal social life of students. Xu and Zhao [19] studied the collaborative relationship between online education and the wireless network of electronic music creation and performance under AI. ey also designed sensor network-related equipment by using a fuzzy clustering algorithm and designed an electronic music creation system by using AI. e simulation results suggested that the mean absolute error (MAE) and mean square error (MSE) of collaborative filtering and fuzzy showed a downward trend on the premise of increasing the number of neighbors. However, when the number of visitors is the same, the filtering matching algorithm is greater than the collaborative filtering algorithm in terms of MAE and MSE. e research transforms the sound characteristics into image structure through an oscilloscope, forms the corresponding sound and image mode, realizes the intelligent matching of online electronic music, and optimizes the effect of online education. Related scholars have studied the actual situation of online education interaction using big data technology and cloud computing. e results show that these two technologies have great advantages for the interactive platform of online education and prove its feasibility [20,21].
rough the above research status, the previous research did not involve the online education reform combining AI and wireless network technology under the background of engineering certification. AI technology and wireless network technology have been deeply researched on the reform of engineering professional online education courses. e innovation of the online education reform being studied lies in the combination of AI and wireless network technology, which has not been studied before. e combination of AI and wireless network technology provides theoretical support for the reform of online education courses, which is of great significance.

AI Technology.
is is the probability algorithm that the platform of engineering professional online education courses [22][23][24] is successfully accessed by college teachers and students. e functions of the engineering professional online education platform are mainly divided into two parts, one is the client of the online education platform, and the other is the backstage management of the online education platform. e first part is divided into four modules, login module, homework viewing module, video course learning module, and personal center module. e second part is also divided into four modules, course management module, resource management module, online monitoring module, and learning data analysis module. Figure 1 is a detailed framework diagram of the functions of the online education platform.
After clicking on the online education course platform for college engineering teachers and students, the specific calculation for the probability of staying on the current page of the platform is shown in the following equation: In equation (1), p 1 represents the probability, α represents the transition probability, and N represents the number of households. College teachers and students perform related operations on the engineering online education platform, and the page jump probability of the platform is calculated as shown in the following equation:   (1) and (2), the calculation equation of PageRank (PR) can be obtained, and the specific calculation is as follows: In equation (3), PR(i) represents the PageRank value of the node of the university teacher and student user on the online education platform. α stands for transition probability. N represents the number of teachers and students on the online education platform of colleges and universities. in(i) represents a collection of related interfaces i through online education platforms. out(j) stands for the collection of interfaces j pointed to by the interface.
In equation (4), Personal Rank is the specific form of the evolution of the PageRank algorithm. Among them, when r i In equation (5), T u i represents the length of time that teachers and students of engineering majors in colleges and universities use the online education platform in the current time sequence. Regarding the efficiency of student learning on the online education platform, it is expounded from two aspects. e first is the effectiveness of video learning, which is divided into three modules, the completion rate of video learning, the total time spent watching the video, and the video multiple viewing rate. e second is the effectiveness of homework learning, which is also divided into three modules, the completion rate of homework learning, the number of times the homework is completed, and the accuracy of completing the homework. Figure 2 is a structural diagram of the effectiveness of online learning for engineering majors in colleges and universities.
If the length of time the university teachers and students use the online platform cannot be judged, then F(u i ) � 0, indicating that the impact of the time the university teachers and students use the online education platform on the calculation of Personal Rank (PR) can be ignored. In this case, adding the dynamic time weight, PR is calculated as follows: Online teachers and students of engineering majors in colleges and universities use the online education platform model, as shown in the following equation: In equation (8), U is the node that represents the online education platform used by university teachers and students, and D is the node that the online education platform switches, as shown in the following equation: e design of the online education platform for engineering majors in colleges and universities is shown in Figure 3. e online education platform is divided into three major frameworks. e first is the presentation framework of the online education platform. e second is the business level of the online education platform. e third is the data support level of the online education platform. ese three framework levels are interrelated and indispensable. e online education platform mainly presents a human-computer interaction interface so that teachers and students in colleges and universities can have a good teaching and learning experience. In addition, according to the actual needs of teachers and students, the business level of the online education platform is used for technical issues such as  Wireless Communications and Mobile Computing the viewing of teaching resources and the modification and improvement of personal information. e business-level logic processing layer can closely link the presentation of the online education platform with the data support layer. e logical processing layer of the business level is also an important part of these three. It transmits the operation requirements of teachers and students to the business logic layer and further transmits the processed data to the data support layer while transmitting the data required by the teachers and students of the data support layer to the platform presentation layer. e data support layer can provide specific services such as viewing, deleting, downloading, and saving teaching resources on the online education platform. e data support layer has massive data to support the normal operation of the entire online education platform. Figure 3 shows the overall structure of the online education platform for colleges and universities.
Perform simulation experiments on the performance of the online education platform for engineering majors in colleges and universities to provide hardware support for the reform of online education courses. Figure 4 shows the specific parameters of the simulation platform.

Wireless Network Technology.
In daily life, people mainly obtain external information through eye observation. However, the observation ability of the human eye is limited, and the eye is easily affected by the changing environment of the outside world. In this case, the photographic element and the image forming device are used to capture image data from the external environment. Second, the vision sensor converts the two-dimensional image into a one-dimensional electrical signal. e essence of the visual sensor is image processing technology, which captures the signal on the surface of the object and presents the image to the relevant researchers. According to different chips, visual sensors can generally be divided into Charge Coupled Device (CCD) sensors and Complementary Metal Oxide Semiconductor (CMOS) sensors. CCD uses the amount of charge to represent the signal and its transmission signal amount in the coupling mode. Its specific functions include photoelectric conversion, information storage, and transmission. CCD has the advantages of automatic scanning, strong spectral sensitivity, lightweight, small distortion, small size, low system noise, low power loss, high durability, and high reliability. It can be well integrated with other elements. Linear CCD can capture one-dimensional images, while planar CCD can capture two-dimensional images, so CCD sensors have been used in various production industries. According to whether a light source is used, vision can be divided into two types: passive light vision and active light vision. e development of CMOS is mainly due to its small size, low power consumption, and low cost. But its image quality is slightly lower than CCD. Common digital products on the market mainly use CCD or CMOS. Low-end cameras mainly use CMOS, and high-end cameras use CCD. e sensor network is an indispensable part of AI. e synergy framework of the online education platform and wireless network is shown in Figure 5. Figure 5 shows the synergy between sensors and wireless network technology.
Sensor-based AI systems include college online education platforms, sensor networks, and wireless network technologies. e communication node and the central gateway node integrate the communication functions well, thus realizing the intelligent integration of college online education platform, sensor network, and wireless network technology, thus laying a solid foundation for the wireless network and online education.
Fuzzy theory can solve linear problems that are difficult to overcome by traditional theoretical systems. e basis of the fuzzy theory is the set of fuzziness, which brings together descriptions of fuzziness. For complex nonlinear problems, it is necessary to go beyond yes or no answers, and the degree of freedom of the elements of fuzzy theory solves this problem well. e fuzzy theory has signs of use in many advanced fields such as industrial control, analysis systems, and sensor systems. e general fuzzy inference system includes the processes of input and output, fuzzification, synthesis algorithm, and defuzzification. e Fuzzy C-means Algorithm clustering algorithm (FCM) [25][26][27] can easily solve the situation of unclear membership and difficult classification. When executing this algorithm, if the number of users is n and the number of items is m, p ij represents the score of the i-th user on the j-th item. Let 1 ≤ i ≤ n, 1 ≤ j ≤ m, so its evaluation matrix is shown in the following equation: According to the evaluation matrix, the membership matrix X can be used to classify very similar users into c clusters, as shown in the following equation:

Wireless Communications and Mobile Computing
X � x 11 x 12 · · · x 1n Set l as the fuzzy index, then d ij is the Euclidean distance between the i-th user and the j-th center of the cluster. To calculate the objective function of the FCM clustering algorithm [28][29][30], according to n users and c user clusters, the data of matrix X is used and calculated, as shown in the following equation: To optimize the objective function of the algorithm, it is necessary to derive its realization conditions. Assuming that there are j (l ≤ j ≤ c) cluster centers c j , the conditions it needs to achieve are shown in the following equations: During the execution of the algorithm, the distance from the user to the center of its cluster, the comparison of matrix data, and the reduction of similarity are often calculated. e purpose of this is to optimize the objective function. e specific steps of the algorithm are as follows: the first step is to initialize; the second step is to select the initial cluster center of the maximum density; the third step is to realize the membership matrix; the fourth step is to assume the results of the t + 1th and t-th iterations, this process satisfies the following equation: e membership matrix and scoring matrix when the iteration is stopped are the final solutions and then proceed to the fifth step. If the result is the opposite, execute again from the second step. e fifth step is to group users according to the membership matrix and scoring matrix to establish user clusters, to realize the classification of other users. e initial cluster canter is selected. To prevent errors in selecting the initial cluster centers and failing to complete the classification, the steps below to select the initial cluster centers during the execution process are needed to follow. e first step is that the score matrix of n users is P, then the density value of each user can be expressed by the following equations: In the second step, equations (15) and (16) are used to calculate the initial cluster centers. e expression of the user's density value is shown in the following equation: e third step is to determine the corrected initial cluster centers. If the initial cluster canter meets the equation (18), then terminate the calculation; otherwise, continue to recalculate according to the first step.
e fourth step is to output the initial cluster canter results.
e login process steps of the online education platform of colleges and universities are briefly described. First, the online education platform for colleges and universities was logged in. e human-computer interface of the platform is opened and the mailbox number is entered to obtain the login verification code. en, fill in the verification code and click login. Finally, check whether the login is successful. If it is unsuccessful, the above operations are repeated until it succeeds.
