Abstract
Internet of Things (IoT) is the inter-networking paradigm based on many processes such as identifying, sensing, networking and computation. An IoT technology stack provides seamless connectivity between various physical and virtual objects. The increasing number of IoT applications leads to the issue of transmitting, storing, and processing a large amount of data. Therefore, it is necessary to enable a system capable to handle the growing traffic requirements with the required level of QoS (Quality of Service). IoT devices become more complex due to the various components such as sensors and network interfaces. The IoT environment is often demanding for mobile power source, QoS, mobility, reliability, security, and other requirements. Therefore, new IoT technologies are required to overcome some of these issues. In recent years new wireless communication technologies are being developed to support the development of new IoT applications. This paper provides an overview of some of the most widely used wireless communication technologies used for IoT applications.
Highlights
There are many applications of the Internet of Things (IoT)
There is an issue of achieving the required QoS performance, energy efficiency, and optimizing the usage of available system resources
Existing protocols are not adopted for IoT applications
Summary
There are many applications of the Internet of Things (IoT). IoT is most abundant in manufacturing, transport, logistics, healthcare, retail, agriculture, process automation, etc. The development of IoT applications requires various technologies to enable device identification, object detection, measurements, networking, data transfer, data analysis, and other processes. There is a number of new wireless communication technologies adapted for IoT applications such as different WSNs (Wireless Sensor Networks), WLAN (Wireless Local Area Networks), LR-WPAN (Low-Rate Wireless Personal Area Networks), and LPWAN (Low Power Wide Area Networks). IoT applications include many different functions such as object identification, event detection, measurements, data processing, etc. We present some of the most used wireless communication technologies used to provide seamless connectivity between IoT components as well as perform data transfer. Network technologies should enable seamless connectivity between different IoT devices and other infrastructure (e.g. cloud systems). New protocols have been developed on almost all layers of the network architecture
