Abstract

Predlaže se arhitektura za IoT temeljena na metaprotokolu za komunikaciju među čvorovima i sustavu pravila za konfiguraciju čvorova. U njoj se ne rabi tradicionalna podjela na slojeve, nego se svaki čvor promatra kao ravnopravan sa svima ostalima. Kategoriju čvora određuje uloga koja je za taj čvor skrojena. Pri tom čvor može biti jednostavan senzorski čvor, ili nešto složenije, kao što je usmjernik ili čvor koji pohranjuje i obrađuje podatke. Čvor može imati i više uloga, a one se ostvaruju ili posebnim programima ili definiraju sustavom pravila, kao u ostvarenom prototipu programske potpore. Čvorovi komuniciraju tim metaprotokolom, koji je temeljen na SQL-ovim podatkovnim operacijama. Poraba takvih operacija omogućuje vrlo veliku fleksibilnost pri osmišljavanju sustavâ. S druge strane, brojni mehanizmi kraćenja poruka i delegiranje određenih stvari nižim protokolima omogućuju stvaranje što kraćih i jednostavnijih poruka, pa tako i uključivanje i onih najjednostavnijih čvorova u takav sustav. Usporedba predloženoga s postojećim znanstvenim i komercijalnim rješenjima pokazuje da se u nekim slučajima očekuju prednosti porabe predložene arhitekture pred tim rješenjima. Te su prednosti najizraženije kad se rabe najjednostavniji čvorovi i kad se zahtijeva konfiguracija mreže po volji na način drugačiji od tradicionalnih arhitektura. -- Metaprotokol za prijenos podataka u IoT-u temeljen na operacijama svojstvenim bazama podataka & Arhitektura sustava IoT-a temeljena na izgrađenom metaprotokolu i sustavu pravila s naglaskom na prilagodljivost i jednostavnost.

Abstract (english)

An arhichitecture for IoT is proposed based on a metaprotocol for communication between nodes and a rule system for node configuration. In it the traditional split into layers is not used, but every node is considered as equal to all others. The node category is determined by the role that was fit for that node. There a node can be a simple sensor node, or something more complex, like a gateway or a data storage and processing node. The node can even have multiple roles, and they are realized either by special programs or defined by a rule system, like in the implemented software prototype. The nodes communicate by that metaprotocol, which is based on SQL data operations. The usage of such operations enables very big flexibility during system design. On the other side, numerous message-shortening mechanisms and delegation of specific things to lower protocols enable creating as short and simple messages as possible, and so also including even those simplest nodes in such a system. Comparison of the proposed with existing scientific and commercial solutions show that in some cases advantages are expected of using the proposed architecture over those solutions. These advantages are most expressed when the simplest nodes are used and when an arbitrary network configuration is required in the way different from traditional architectures. -- Metaprotocol for data transfer in the IoT based on operations attributed to databases & Architecture of IoT systems based on the developed metaprotocol and rule system with focus on adaptability and simplicity.
