I. Introduction
In recent years, Internet has reached a new stage of development, due to significant increase in the capacity to gather information, analyze it and transform it into a useful knowledge. Most importantly that on each of these steps human involvement in the process of data processing reduces as the technology evolves. The Internet is becoming the Internet of things. The ideology of this new Internet is aimed at increasing efficiency of the economy by automating processes and minimizing human involvement. Self-organization, fault tolerance and adaptability play an important role in building the “Internet of Things”. Therefore, the ability to collect data by means of sensors and wireless transmission becomes even more valuable.
