Abstract

Kroz ovaj diplomski rad proučene su osnove rada simulatora bežičnih senzorskih mreža kao i generalni pregled najpopularnijih simulatora poput Ns-2, Ns-3 i OMNeT++a. Detaljan naglasak stavljen je na simulator Cooja i operacijski sustav Contiki koji su u detalje razrađeni. Dodano je i poglavlje koje opisuje rad sa simulatorom i glavne karakteristike svakog programa pisanog za operacijski sustav Contiki. Razrađen je mehanizam LEACH čije su dvije implementacije izrađene za operacijski sustav Contiki. Naveden je i opis korištenog energetskog modela. U posljednjem poglavlju navedene su postavke simulacije kao i usporedba između dvije definirane implementacije koja je prikazana kroz trenutke kada je ispao jedan čvor, trenutak kada su ispali svi čvorovi, te ukupan broj bitova poslan baznoj stanici.

Abstract (english)

The main topic of this graduate thesis was the working principle of wireless sensor network simulators and the general overview of the most used simulators like Ns-2, Ns-3 and OMNeT++. A detailed look was give to the Cooja simulator and Contiki operational system. An additional chapter was created to give a basis of working with the Cooja simulator and basic elements of every program written for Contiki OS. There is a detailed overview of LEACH mechanism whose two versions were implemented on the Contiki OS. A detailed look in the energy model used in LEACH implementation was also given. In the last chapter there are is the setup for the simulation and the used parameters. Finally there is a comparison between the two implementations which is showcased through things like network failure when first node is down, network failure when last node is down and the number of bits received by base station.
