Internet of Things(IoT) is extremely broad phrase, and can mean a great many different things. But it does not change the fact that each day more and more devices all over the world are being connected to the Internet. At that rate, Internet of Things (IoT) development projects are gaining popularity to say the least.
Though some people question the use of Java in IoT it is not surprising to see Java as being the most popular among developers who are working on IoT solutions. The practicality of the statement “write once, run anywhere” still predetermines the choice in a great measure.
Java advantages are apparent. It is an object-oriented and platform independent language. Thus coding and debugging can be done on desktop and moved to any chip with a Java Virtual Machine afterwards. Therefore code can be run not only on places where JVMs are common (servers and smartphones), but also on the smallest machines. Minimum hardware dependency is a huge plus. This also means that Java is great from an economic standpoint: devotion to Java coding can pay back across various platforms.
Besides, by now Java has attracted an active community of millions software developers and is being taught as one of the primary programming languages in the majority of engineering degree programs. Consequently, finding someone skilled in Java programming should not constitute a problem.
Last but not the least, maturity and stability of this language make it even more attractive. When there are devices that are going to be remotely managed and provisioned for a long period of time, Java’s stability and care about backwards compatibility become important.
It should be taken into consideration thought that your choice of IoT platform should support Java. You should make sure available hardware support libraries should have control functions according to your requirements too.
Created to program the telephone switches C programming language has almost monopolized embedded systems programming. Its proximity to machine language makes it impressively fast.
C can create compact and faster runtime code. Still it should be noted that runtime speed isn’t the primary aspect of development to consider. Development speed should also be takes into account (and other languages may be much more efficient in that).
Another vote for stems from the fact that majority of the modern languages follow the syntax of C, which means that it is easy to learn and effective in accomplishing advanced tasks.
As both completing complex tasks and finding developers with extensive experience in C is relatively easy, its applicability to IoT projects speaks for itself.
Still, there are some drawbacks of C that make it less preferred in today’s development world, e.g. poor data security and no run time checking mechanism.
Although Python originally is widely chosen for Web development, it has significantly gained popularity in the IoT coding arena for the past few years. Such huge advantages as its flexibility, writability, error reduction, and readability contributed to that greatly. Distribution of compact executable code is easy. Working in programming teams is easy. Known as organized and neat, its elegant syntax is great for database arrangement. Sure, Python is a good choice for building applications that take data, convert it into any sort of a database format and draw upon the tables for control information. Python also has libraries for all 3 main IoT protocols such as TCP/IP, Bluetooth and NFC.
Additionally, IoT projects involve lots of data analytics and Python has rich modules for that.
Finally, major IoT hardware platforms and micro-controllers, e.g. Arduino, Raspberry PI, Intel Galileo, are enabled for interactive communication through Python.
Probably, the main problem for Python is its runtime speed, especially in comparison to C. Still there is a number of ways to optimize the code so it runs more efficiently.
Steady increase in popularity of Python for IoT is evident.
So which programming language is the best for IoT?
No definite answer, guys… All the above languages influence the IoT space up to an extent. However, the preference of language today depends on the end use of the app, product or service you want to create. What do you think? I’d love to hear your thoughts in the comments!
