The main advantage of edge processing in IoT is primarily:

The primary advantage of edge processing in the Internet of Things (IoT) is indeed reduced bandwidth usage and latency. Edge processing allows data to be analyzed and processed closer to the source, rather than sending all raw data to a centralized cloud for processing. This is particularly important in IoT applications, where devices generate a significant amount of data.

By processing data at the edge, only relevant information needs to be transmitted to the cloud, leading to decreased bandwidth utilization. This is especially beneficial in scenarios where network capacity is limited or when there are high costs associated with data transmission. Furthermore, processing data locally reduces the time it takes to respond to events, thereby minimizing latency. Low latency is crucial for applications that require immediate responses, such as autonomous vehicles or real-time monitoring systems.

While security protocols, data redundancy, and compatibility with outdated systems are important considerations in IoT infrastructure, they are not the primary benefits associated with edge processing. These aspects may play a role in the overall design and functionality of IoT systems, but the significant efficiency gains in bandwidth and speed that edge processing delivers are what make it a key feature in modern IoT architectures.
