Brief announcement: Fun in numbers - A platform for sensor-based multiplayer pervasive games

We examine multi-player pervasive games that rely on the use of ad-hoc mobile sensor networks. The unique feature in such games is that players interact with each other and their surrounding environment by using movement and presence as a means of performing game-related actions, utilizing sensor devices. We briefly discuss the fundamental issues and challenges related to these type of games and the scenarios associated with them. We have also developed a frame- work, called Fun in Numbers (FinN) that handles a number of these issues, such as such as neighbors discovery, localization, synchronization and delay-tolerant communication. FinN is developed using Java and is based on a multilayer architecture, which provides developers with a set of templates and services for building and operating new games.
