Sensor nodes in wireless networks often run on batteries, which means they have relatively little energy. Energy conservation is a priority while developing a WSN. Clustering is a well-known technique for extending network lifespan. More sensor networks and data must be processed as a result of big data growth. The question of how to jointly cluster sensor nodes and reach the ideal number of nodes in a large data WSN remains unanswered. As the fundamental component of data analysis, clustering is important. On the one hand, as information has grown and topics have intersected, there are now various methods for cluster analysis. And from the other hand, because of the complexity of the information, each clustering technique has distinct advantages and disadvantages. In this review article, we start with the concept of clustering, explore the fundamental components of the clustering procedure, such as the indicators used to measure and evaluate distance or similarity, and study the clustering algorithms both from a conventional and a contemporary viewpoint. However, the segmentation performance might be noticeably adversely affected by the presence of noise. The idea of sub-graph affinities is used to reduce the influence of visual noise, and each node in the main graph is represented as a sub-graph that describes its immediate surroundings. Then, in order to combat the uncertainty picture noise by leveraging additional information, a statistically sub-graph affinity matrix is created based on the statistical associations between sub-graphs of linked nodes in the main network. First, the consists of several modules for the multifunctional load characteristics analysis are created, together with the structure of the software system. Moreover, the earlier indicated and the proposed design of several significant function modules of the program system are described. Then, the approach of multifunctional user load characterisation is introduced. The multifunctional user load characterisation system's application example is shown last. According to simulation findings, APs below the noise level may be recognised utilising SWT with a carefully chosen mother wavelet, coupled to an adjustable threshold, allowing on-line AP detection performed on a programmable digital integrated circuit.
