Mobile devices are present in people’s everyday lives and have gone from being a tool used purely to communicate. Currently they are also used as a means to entertain, by listening to music, watching videos or playing games. When it comes to games, these can be played alone (single player games) or with other people (multiplayer games), from strangers to family and friends. Local multiplayer games are a popular choice because they connect groups of physically close people to play and allow them to interact. However, there are some concerns to address. Local multiplayer games connect de vices but that alone isn’t enough to ensure correct game play. These games need to distribute the game state between the devices and solve the issues that ensue from that. These involve matching players, managing game state (making sure players get the cur rent state in a reasonable time frame, in order for the next moves to be performed), dealing with player inflow and outflow, among other problems. To reliably handle the aforementioned issues, in this thesis we propose Peppermint, a framework and runtime system to program local multiplayer games on the mobile edge. It was developed on top of Basil GardenBed, a data storage and dissemination system for the mobile edge developed at NOVA LINCS, that provides communication between devices. On the other hand, the challenges stemming from the games’ execution will be addressed by our framework, which are validated by the development and evaluation of one game according to a set of functional metrics. The results obtained during testing of our framework, mostly in a simulated setting, show that the framework is able to create and store matches, letting players join, leave and play in them. It will also discard the generated data when the match ends, so that the network doesn’t end up being cluttered with data that isn’t being accessed anymore. These characteristics constitute a framework has a set of core features that can be expanded in future work.
