Whether it's a smart home, a connected car or a smart factory, the core of all smart technologies is the interconnection of devices, and this is what we know well about the Internet of Things (IoT). The way IoT develops is constantly improving the way people live and interact. Companies can gather effective information to streamline operational processes, anticipate major changes, and ensure that customers' real-time needs are met. Users can have a smarter lifestyle instead of wasting time on cumbersome things. IoT has great promise, but for developers, there are some unique challenges when building an IoT system. Limited battery life Take a tablet computer, for example, a computer of the size of a mobile phone. Although fully functional, the large screen is not necessarily convenient, and the larger the screen, the smarter hardware requires a larger battery. If the computer is smaller, the amount of battery it needs is the same. While it seems that battery life issues fall into the field of hardware engineers, some UX and professional software development methods can also effectively increase the battery life of the device: Use black: Black pixels in the AMOLED screen (no backlight module required) maximize battery life. In general, brighter colors in the display's contrast ratio consume more power than darker colors. Use JPEG whenever possible: Although PNG is more popular for its flexibility and support transparency, JPEG is still a better compression format. According to Stanford University research, the JPEG standard can reduce power consumption more than PNG. Reducing network requests: While there are times when you need to query data connectivity in real time, you need to use these techniques carefully, especially for encrypted data. Reduce JavaScript: There are a lot of bandwidth/power consumption factors in the application, the biggest of which is the use of Javascript. When the browser encounters the "script" tag, the script code will run first. Data management: "Catch everything" is not the end result In order to truly take full advantage of the IoT system, you need to ensure that the features provided are all secure. When it comes to big data, as stated by Forbes, the motto "If you can't measure it, you can't manage it." It's really useful in the IoT world. It is now common for software developers to make the mistake of collecting as much data as possible without considering the actual purpose. Regressing battery life, you want to save battery, you only need to collect limited data in data processing. In terms of data security, it ultimately needs to be handled in an open ecosystem, and this is also a new area that is still being developed. Therefore, you need to understand industry trends. Compared with other mobile phone development projects, ensuring user rights on a required basis can effectively ensure device security. Of course, digital threats are not the only ones worth worrying about. If you manage your users' personal data, you need to be protected from social engineering attacks. Emerging standards Although the Internet of Things is portrayed as an ecosystem and devices work in harmony, the reality is a bit different. As an emerging industry, a large number of new companies compete to become dominant companies. While some products are completely isolated by trusted vendors, other systems are completely open. The biggest challenge for developers is to deal with potential interference between devices. To help overcome these challenges, Open ConnecTIvity FoundaTIon is currently developing an open standard to overcome the problems of the aforementioned devices being developed independently of each other. The biggest benefit from the draft specification is that complete operability requires building engineering—vertical services, platforms, and connections—in all layers of the development stack to ensure a successful user experience. The OCF standard primarily uses abstraction to simplify development workflows while ensuring that data protocols are dynamic and layer-agnostic. Five methods followed by the standard: create; Search Update delete; Notice. The IEEE also has a wide range of IoT standards. Designed for everyone Perhaps the biggest challenge in IoT development is to meet the needs of all users. To be truly successful, connected devices can't be targeted at tech-savvy users. For example, smart homes involve the entire ecosystem that utilizes equipment. Locks, thermostats, lighting, alarms, etc. – these are the foundation of smart homes. There are also machine-to-machine (M2M) projects such as smart grids, general building automation, vehicle-to-vehicle communications, and wearable communications equipment. It looks overwhelming, right? Actually not. Take a look at the iPhone or Amazon Echo - both are significant examples of UX designs that adapt to different users. In the past, visual effects were the cornerstone of the success of the user experience platform, however, the future is the conversational UI world. This will open a whole new door to the user experience. to sum up As with many other development challenges in the world today, these complex challenges can be followed by lean and agile principles in the development workflow. By focusing on the development of small parts of the product, high quality code should be ensured in a fiercely competitive market.
