Implementation of data aggregation in IoT

Implementing data aggregation in the Internet of Things (IoT) is an intricate process involving several steps:

Step 1: Data collection

The process begins with data collection, which involves gathering data from multiple IoT devices. This data can be varied, both in terms of type and source. However, its raw and unstructured nature at this stage makes it challenging to directly derive meaningful insights.
Step 2: Data pre-processing

Once the data is collected, it moves on to the pre-processing stage. Here, the raw data is cleaned and standardised. It involves removing inconsistencies, filling in missing values, and resolving conflicts to ensure the data is fit for statistical analysis.
Step 3: Data aggregation

The next step is data aggregation, where the pre-processed data is compiled and summarised into a more digestible format. This process involves transforming the data by calculation, sorting, or grouping to provide a summary that can offer useful insights.
Step 4: Data analysis

Finally, the aggregated data is analysed. This is where the data is examined in-depth to uncover trends, patterns, and correlations. With the help of data analysis tools, valuable insights are extracted from the aggregated data, which can then be utilised for decision-making.
