What is Top 6 Challenge Of IoT

By on July 2, 2019 0 1074 Views

The IoT provides many new opportunities to the industry and users in many application fields. Currently, however, the IoT itself lacks theory, technology architecture, and standards that integrate the virtual world and the real physical world in a unified framework. So follow us in order to list the top 5 challenges of IoT.

Architecture Challenge

IoT encompasses an extreme wide range of technologies. Also IoT involves an increasing number of smart interconnected devices and sensors (cam-eras, biometric, physical, and chemical sensors) that are often nonintrusive, transparent, and invisible.

As the communications among these devices are expected to happen anytime, anywhere for any related services, generally, these communications are in a wireless, autonomic, and ad hoc manner. In addition, the services become much more mobile, decentralized, and complex.

In IoT, data integrations over different environments are thus tough and will be supported by modular interoperable components. Also Infrastructure solutions will require systems to combine volumes of data from various sources and determine relevant features, to interpret data and show their relationships, to compare data to historical useful information, and support decision-making. Single reference architecture thus cannot be a blueprint for all applications. Heterogeneous reference architectures have to coexist in IoT.

 Architectures should be open, and following standards, they should not restrict users to use fixed, end-to-end solutions.

IoT architectures should be flexible to cater for cases such as identification (RFID, tags), intelligent devices, and smart objects (hardware and software solutions).

Technical Challenge

 IoT technology can be complex for variety of reasons. First, there are legacy heterogeneous architectures in the existing networking technologies and applications, e.g., different applications and environments need different networking technologies, and the ranges as well as other characteristics of cellular, wireless local area network, and RFID technologies are much different from each other.

Second, communication technologies, including fixed and mobile communication systems, power line communications, wireless communication, and short-range wireless communication technologies, for both fixed and mobile devices, either simple or complicated, should be low cost and with reliable connectivity.

 At last, there are thousands of different applications, it is in natural to have different requirements on what parties need to communicate with each other, what kind of security solutions are appropriate, and so on.

To summarize, complexity and alternative technologies may introduce problems; unnecessary competition and deployment barriers in markets may also introduce problems; systems and communication mechanisms with unnecessary dependencies may block the migration of IoT systems to the most economic and efficient platforms. All the above may block IoT to connect as many “Things” as possible.

Hardware Challenge

Smart devices with enhanced inter-device communication will lead to smart systems with high degrees of intelligence. Its autonomy enables rapid deployment of IoT applications and creation of new services. Therefore, hardware researches are focusing on designing wireless identifiable systems with low size, low cost yet sufficient functionality.

As the bandwidth of IoT terminals could vary from kbps to mbps from sensing simple value to video stream, requirements on hardware are diverging. However, two requirements have been nevertheless the essentials: one is the extremely low power consumption in sleep mode and the other is ultra-low cost.

Suppose the sleeping time over active time is one million, the leakage power of an IoT terminal shall at least be one million time less than that of active. It is so far impossible when an IoT terminal is sleeping and receiving RF signals. It will be even difficult when using advanced CMOS silicon with relatively more leakage power. Hardware and protocol code sign for sleeping has been thus the first hardware challenge of IoT.

Billions of IoT terminals will be used; the cost of an IoT terminal must be ultra-low. However, so far, there is no low cost positioning solution for IoT, especially the positioning precision of a short-range IoT terminal must be high.

In another way, not yet used very narrow spectrum band between two used bands may have to be used by future IoT. To use very narrow band with strong power neighbors, the cost of passive component will not below and that will definitely be a potential challenge in the future.
