Abstract:V diplomskem delu smo na kratko opisali brezžični protokol MiWi, kateri izhaja iz protokola ZigBee (IEEE 802.15.4). ZigBee je bil v osnovi zamišljen kot WPAN odprt standard za radijsko omrežje, ki bi bil alternativa za ostala brezžična omrežja Bluetooth in Wireless. Protokol je primeren za uporabo v brezžičnih senzorskih omrežjih, primernih za industrijsko okolje. Gre preprosto zato, da imamo neko množico elementov (gradniki ZigBee omrežja oz. senzorska vozlišča) omrežja, povezanih med seboj tako, da tvorijo omrežje za prenos podatkov na kratkih razdaljah 10-100m. Vendar so ti podatki količinsko zelo majhni. Prednost takega omrežja je v tem, da se podatki pošiljajo v majhnih paketih (količinsko omejeni), hkrati pa so gradniki omrežja aktivni samo takrat, ko pride do prenosa podatkov (paketov). Takrat kadar ni prenosa podatkov se gradnik (njegov radijski del) izklopi in s tem privarčuje pri energiji. To pomeni, da so takšni gradniki omrežja primerni za aplikacije v težko dostopnih območjih (industrijska okolja), ker ne potrebujejo vzdrževanja in bi bila zamenjava vira energije (baterija) za njihovo delovanje možna z velikimi napori in stroški. Ker je po določenem obdobju uporabe ZigBee protokola, združenje ZigBee Aliance ta protokol postopoma nadgrajevalo, je postal zelo kompleksen. Zato se je porodila ideja, kako napraviti omrežje, ki temelji na ZigBee protokolu in je bolj prijazno do uporabnika. Tako je nastal protokol MiWi, ki je opisan v diplomski nalogi. V diplomski nalogi, je v praktičnem delu predstavljeno, kako postaviti enostavno “peer-to-peer“ brezžično senzorsko povezavo v brezžičnem senzorskem omrežju z uporabo protokola MiWi ter praktični primer pošiljanja podatkovnega paketa določene dolžine in vsebine preko omrežja.

Title:MiWi WIRELESS SENSOR NETWORK
Abstract:In these thesis we briefly described the MiWi wireless protocol which derives from the protocol ZigBee (IEEE 802.15.4). ZigBee was basically conceived as a WPAN (wireless personal area network) is an open standard for radio network that would be an alternative to other wireless networks Bluetooth and Wireless. The protocol is suitable for use in wireless sensor networks suitable for industrial environments. It is simply that we have a set of elements (building blocks of ZigBee network or Sensor node) networks connected to each other to form a network to transmit data over short distances 10-100m. However these data are quantitatively very small. The advantage of this system is that the data is sent in small packages (limited quantity) as well as network components active only when there is a transfer of data (packets). At that time when there is no data transfer the widget (its radio module) switched off and thereby saving energy. This means that such network components are suitable for applications in hard to reach areas (industrial environment) because it does not require maintenance and the replacement of the energy source (battery) for their operation possible with considerable effort and cost. Because after a certain period of ZigBee protocol Association Aliance ZigBee protocol that progressively build on it has become very complex. Therefore the idea of how to make network based on the ZigBee protocol more user-friendly. This has resulted in MiWi protocol which is described in my graduate thesis. In this graduate thesis, the practical work illustrates how to set up simple “peer-to-peer” wireless sensor link in a wireless sensor network using MiWi protocol and a practical example of sending a data packet certain length and content over the network.
