Deze scriptie handelt over een vergelijkende studie van peer-to-peertechnologieën op het Android-platform. Hierbij ligt de focus op het recentere Wi-Fi Direct. De hoofdstukken 1 en 2 behandelen respectievelijk het stagebedrijf en de resultaten van het literatuuronderzoek dat typisch aan de uitwerking van een masterproef voorafgaat.In hoofdstuk 3 wordt Wi-Fi Direct beoordeeld a.d.h.v. een aantal experimenten. Hieruit is gebleken dat de cijfers rond bandbreedte en bereik uit de documentatie behoorlijk optimistisch zijn. Daarenboven zijn de authenticatiemethoden slechts nuttig in een beperkt aantal scenario's. Desondanks biedt deze technologie zeker een aantal voordelen ten opzichte van alternatieven zoals Bluetooth, NFC, enzovoort. De implementatie van Wi-Fi Direct wordt behandeld in hoofdstuk 4. Hierbij werd een uitbreiding geïmplementeerd die de optie aanbiedt om de manuele acceptatie uit te schakelen. Vervolgens werd er bestudeerd of er een uitbreiding van de authenticatiemethoden mogelijk was. Dit is echter te complex gebleken om te behandelen binnen de resterende tijdsperiode. Het onderzoek hieromtrent werd evenwel gedocumenteerd.Vervolgens worden in hoofdstuk 5 nog enkele potentiële uitbreidingen vermeld en tot slot volgt de conclusie van deze masterproef. This thesis is a report on a comparative study of peer-to-peer technologies on the Android platform. The main focus lies on Wi-Fi Direct.Chapters 1 and 2 describe the workplace and the results of a literary study that preceded this research.In chapter 3, Wi-Fi Direct performance is experimentally evaluated. These experiments showed that both bandwidth and signal strength aren't as good as online documentation specifies. On top of that, the provided authentication methods are only useful in a specific number of scenarios. Nevertheless, this technology offers certain advantages over alternatives such as Bluetooth, NFC, and so on.Wi-Fi Direct implementation is discussed in chapter 4. Which also entails the implementation of an additional feature that allows the developer to enable automatic acceptation of connection requests. Next, some additional research was done to determine whether or not the authentication procedure could be adjusted. Unfortunately, implementing this adjustment didn't prove to be possible considering the time frame. Nevertheless, this research was also documented.Next, chapter 5 brings forward a few potential ways in which this research can be continued. And finally the conclusion of this research is discussed.
