1- Network Connectivity and Traffic Management

In the IoT sphere, network connectivity and traffic management serve as the heart and blood vessels of the human body, safeguarding the seamless flow of information. Effective IoT network traffic management uses policies to prioritize, limit, or block types of traffic, mitigating congestion and enhancing network performance. This process is enhanced by Software-Defined Networking (SDN), which allows for fine-grained control and dynamic policy updates in real-time based on the current state of network traffic.

In addition, the utilization of Token Bucket algorithms and cooperative traffic management across multiple switches mitigates packet loss and guarantees prioritization of real-time traffic in IoT networks.

Future IoT network traffic management improvements may involve the integration of network devices, such as Graph Neural Networks (GNNs) and Multi-Armed Bandit (MAB) algorithms with SDN.

2- Remote Monitoring and Control Capabilities

The capability to remotely manage and control IoT devices offers a comprehensive view of the entire network. The core components of an IoT remote monitoring system include data acquisition, data analytics, and event notification, with sensors or overlay sensors capturing data for cloud-based analysis. Software known as an ‘agent’ or ‘edge’ captures data from remote assets and securely transfers it to a central repository.

IoT remote monitoring allows for near real-time tracking of various parameters like temperature, pressure, and humidity, remotely accessible via internet-connected devices. Integrating IoT devices with cloud backup solutions and network segmentation enhances network security through continuous monitoring and proactive defense against attacks. These analytics within remote monitoring systems assess core operating parameters and use historical data to identify multivariate issues and trends.

3- Data Collection and Utilization

Data serves as the vital element of any IoT network, and its effective collection and use are imperative for informed decision-making. Cloud computing provides a model for enabling ubiquitous, convenient, on-demand network access, which is essential for managing IoT low power networks. Ensuring synchronization between the cloud and gateways is critical in IoT device management, allowing seamless communication with gateways via the cloud service.
