How will IoT Devices or Systems cope with the crowded network?


The Internet of Things (IoT) is rapidly expanding, with an estimated 30 billion devices connected globally as of 2024. This number is projected to exceed 64 billion by 2025​ (The Tech Report)​​ (Techjury)​. With such explosive growth, ensuring these devices can function effectively in increasingly crowded networks is critical. This blog delves into the latest strategies and technologies enabling IoT systems to cope with network congestion.

The Challenge of Network Congestion

Network congestion occurs when the demand for bandwidth exceeds the available capacity, leading to slower speeds and potential data loss. This issue is exacerbated in IoT environments where numerous devices share the same network resources. Key factors contributing to network congestion include high device density, large data volumes, and real-time communication requirements.

Advances in Network Technologies

5G Deployment: The widespread rollout of 5G technology is pivotal for supporting the growing number of IoT devices. 5G offers higher bandwidth, lower latency, and the capacity to handle more simultaneous connections compared to previous network generations, making it ideal for IoT applications that require real-time data transmission​ (Exploding Topics)​.

Low-Power Wide-Area Networks (LPWAN): Technologies such as NB-IoT (Narrowband IoT) and LoRaWAN (Long Range Wide Area Network) cater to IoT applications that need long-range connectivity with low power consumption. These networks are essential for devices that transmit small amounts of data intermittently, like environmental sensors and smart metres​ (Techjury)​.

6G and Satellite Integration: Future advancements like 6G and satellite-enabled LPWANs promise to revolutionise IoT connectivity by providing ubiquitous coverage, even in remote areas, ensuring continuous connectivity for IoT devices under any conditions​ (Techjury)​.

Enhanced IoT Protocols and Standards

5G towers and LPWAN technology in useEdge Computing: By processing data closer to its source, edge computing reduces the burden on central networks and lowers latency. This is increasingly adopted in IoT to handle data locally, sending only essential information to central servers, thereby reducing network congestion and enhancing data security and processing speed​ (Exploding Topics)​.

IPv6 Adoption: The transition to IPv6 is crucial for the scalability of IoT. Unlike IPv4, which supports about 4.3 billion addresses, IPv6 can handle an almost infinite number of unique IP addresses, ensuring efficient network management and communication for IoT devices​ (Intellipaat)​.

Improved IoT Device Capabilities

Self-Healing Networks: IoT devices are becoming more autonomous with self-healing capabilities, allowing them to detect and address network issues independently. This ensures continuous operation even under suboptimal network conditions​ (Intellipaat)​.

AI and Machine Learning: Integrating AI and machine learning into IoT systems helps predict network congestion and dynamically allocate resources. These technologies optimise data transmission routes and prioritise critical communications, enhancing overall network efficiency​ (Intellipaat)​.

Using Virtual Test Networks to Assess Device Performance

Implementing virtual test networks allows IoT developers and engineers to simulate real-world conditions and evaluate device performance under various network scenarios. By replicating network congestion, latency issues, and bandwidth constraints, virtual test networks provide valuable insights into how IoT devices will perform in practical deployments. This proactive approach helps identify potential bottlenecks early in the development cycle and ensures devices can maintain optimal functionality in crowded network environments.

Security and Data Management

market is projected to reach $1.1 trillion by 2023, driven by the need to protect data and devices from cyber threats. Implementing strong encryption, secure boot processes, and regular firmware updates are essential practices to safeguard IoT ecosystems​ (The Tech Report)​​ (Exploding Topics)​.

Data Decentralisation: Distributed ledger technologies like blockchain enhance the security and reliability of IoT data. These technologies provide transparent and tamper-proof records of all transactions, making it difficult for malicious actors to interfere with IoT networks​ (Intellipaat)

Application-Specific Strategies

Healthcare IoT (IoMT): The Internet of Medical Things (IoMT) is transforming healthcare by enabling remote patient monitoring and telehealth services. Utilising secure, low-latency networks, IoMT devices ensure continuous and reliable communication of patient data to healthcare providers, improving patient outcomes and reducing costs​ (Intellipaat)​.

Smart Agriculture: IoT devices in agriculture use precision farming techniques, including sensors to monitor soil moisture, weather conditions, and crop health. LPWAN technologies provide wide coverage with minimal power consumption, ensuring efficient farm management and increased productivity​ (Intellipaat)​.

As the IoT ecosystem continues to expand, coping with crowded networks requires a multifaceted approach. Advances in network technologies, enhanced device capabilities, improved security measures, and application-specific strategies are all critical components in ensuring IoT devices can function efficiently in increasingly congested environments. By leveraging these innovations, IoT systems can provide reliable and robust connectivity, driving the next wave of digital transformation across various industries.
