Analysis of network traffic related to user interactions with non-player characters in a 3D videogame

U ovom diplomskom radu višekorisnička umrežena videoigra „Wizard wars“ nadograđena je kreiranjem računalno-generiranih likova koristeći pokretačku platformu za igre Unity. Provedeni su eksperimenti s tri različite mrežne konfiguracije, pri čemu su računala krajnjih korisnika bila međusobno povezana putem putem virtualne privatne mreže kroz Internet. Mrežni promet tijekom igranja snimljen je s pomoću alata Wireshark. Iz snimljenog prometa izdvojena su međudolazna vremena i duljine paketa protokola Transmission Control Protocol (TCP) za daljnju analizu. Nadalje je provedena identifikacija distribucije slučajne varijable te su identificirane razdiobe za međudolazna vremena. Također su prikazani histogrami izračunatih distribucija i stvarnih podataka. Za sve tri mrežne konfiguracije uspoređeni su histogrami dobivenih duljina paketa.In this master's thesis, a multiplayer videogame „Wizard wars“ based on Unity game engine has been upgraded by adding non-player characters. Experiments were conducted in three network configurations, in which the connection between the end-user computers was established through a virtual private network across the Internet. Network traffic was captured by using Wireshark. From the captured traffic, mean Transmission Control Protocol (TCP) packet length and interarrival time were extracted for further analysis. For the packet interarrival time, the random variable distribution was identified, and histograms were plotted that show the identified distribution against the actual data. For the packet length, histograms were compared for all three network configurations
