Unearthing the State of Art in IoT: A Literature Review on the Internet of Things
The Internet of Things (IoT) has now become a substantial industry, worth $1.47 trillion in 2019 and projected to reach $6.67 trillion by 2025. It is transforming the way we live and work, creating intelligent environments, and offering limitless possibilities for interconnectivity. In this article, we present a comprehensive literature review of the current state of IoT technology.
What is the Internet of Things?
IoT refers to the connection of physical devices and everyday objects to the internet through wireless networks, enabling them to collect and exchange data. These devices can range from smart home appliances, wearable technology, and industrial machinery to traffic lights and environmental sensors.
The Current State of IoT
The current state of IoT technology can be described in three key areas: connectivity, data analytics, and security. One of the prevailing issues for IoT is connectivity, with low-power wide-area networks (LPWANs) offering a cost-efficient solution to extend machine-to-machine communications.
The use of data analytics will be the driving force behind IoT, with machine learning and artificial intelligence being essential components. The volume of data generated by these devices is enormous, necessitating a means to capture, analyze, and derive actionable insights.
Security remains a huge concern for IoT, as the wide variety of connected devices can provide easy access points for malicious actors. Current security measures such as authentication protocols, encryption, and firewalls have been effective, but there is still a need to improve security across the entire IoT ecosystem.
Applications of IoT
IoT technology has numerous applications across industries. Smart homes are becoming more popular, with smart lighting, thermostats, and home security systems. In the healthcare industry, wearable technology is increasingly being used to monitor patients’ vital signs and transmit data to healthcare providers.
The industrial sector is also adopting IoT technology, with the use of sensors and data analytics enabling manufacturers to optimize production processes, reduce costs, and minimize downtime.
Conclusion
In conclusion, the Internet of Things as an industry is expected to grow exponentially in the coming years, and the potential applications are endless. Companies that can successfully leverage the power of data generated by IoT devices will be at a considerable advantage. However, security and privacy remain significant concerns that need to be addressed proactively. The future of IoT looks bright, and it will continue to redefine the way we interact with technology in our daily lives.
