Internet of Things (IoT) Embedded Hardware Design Challenges
The market for embedded systems has expanded significantly since the introduction of the internet of things, or IoT, as a result of the connected devices' quick development. Because of the Internet of Things, embedded intelligent connectivity keeps growing at an incredible rate.?

Role of Embedded Systems in IoT?
The process of equipping objects with sensors, actuators, and processors is known as the Internet of Things (IoT). It involves hardware board design and development, software systems, web APIs, and protocols, all of which work together to create a networked environment of embedded systems. The ability of technologies to connect across various platforms, devices, and networks in this connected environment is generating a web of communication that is transforming the way we engage with the outside world digitally. Connected embedded systems are altering how we interact and behave with our surroundings, with our homes, with our communities, and even with our own bodies.?
?Commercial systems with a wide range of functions, such as vending machines, smart kiosks, AC controllers, connected cars, hotel bill printers, etc., are examples of embedded systems that are all around us. Therefore, when it comes to designing these embedded IoT systems, they must be made for a specific purpose and have attributes of a well-designed product, such as a processor that is dependable, low power consumption, and secure architecture. It is not simple to design an embedded IoT hardware system, though.?

Challenges of Designing an Embedded IoT Hardware System?
In the IoT ecosystem, designing hardware for embedded devices necessitates careful, in-depth planning. The reason is that creating a hardware system for Internet of Things (IoT) enabled devices presents a number of difficulties for embedded designers. Some of the difficulties in designing embedded IoT hardware systems are listed below:? ?
● Lack of necessary flexibility for running applications over embedded systems:?
? With the rising demand for connected devices, embedded systems need to work with heterogeneous devices and adapt to different networking architectures to cope-up with new functionalities and performances in the real-time environment. Due to this situation of increasing technology adoption and deployment of new applications, embedded system designers face several problems in terms of flexibility while developing embedded IoT systems such as:?
?
● Security crisis in embedded system design:?
All the IoT hardware products need to perform securely in the real-time embedded environment. Since all the embedded components operate in a highly resource-constrained and in physically insecure situations, engineers often face problems in ensuring the security of these embedded components. These systems have to be designed and implemented to be robust and reliable and have to be secure with cryptographic algorithms and security procedures.

● High power dissipation of embedded system design:?
Another increasingly aggravating limitation is power dissipation of microprocessor?hardware design?for getting the best performance out of real-time applications and devices. The persistent challenge is how to deploy an embedded system with an increasing number of transistors and with an acceptable power consumption ratio. There are two causes of high power dissipation in designing low-power embedded systems:?
First, because the power dissipation per transistor is increasing with the increase in gate density, the power density of system on chips is set to increase. Thus, the engineers must reduce overall embedded systems’ power consumption by using efficient system architecture design rather than relying on process technology alone.?
Second, engineers focus on better performance with low power consumption by increasing the frequency of the system, which burns more power. Engineers need to pay more attention to design choices as well.?
● Problems of testing an embedded system design?
For ensuring a reliable product design, conducting in-depth testing, verification, and validation is another challenge.?
?
● Inadequate functional safety of safety-critical embedded systems:?
Functional safety is considered as a part of a product’s overall safety. Embedded systems are considered as generalized control systems, which perform various control functions that require autonomy, reconfiguration, safety, fault-tolerance and need to eliminate all the unacceptable risks to meet functional safety requirements. These considerations highly influence their use in applications, where many functional loops are competing for the design of computational resources due to which, a number of timing and task-scheduling problems arise.?
● Increased cost and time-to-market:?
Apart from flexibility and security, embedded systems are tightly constrained by cost.?
In embedded hardware design , the need originates to derive better approaches from development to deployment cycle in order to handle the?cost modeling?or cost optimality with digital electronic components and production quantity. Hardware/software code-designers also need to solve the design time problem and bring embedded devices at the right time to the market.?
