take a different approach and study how to incentivize cooperation in P2P systems based on peers ’ effort, i.e., contribution relative to capacity. We make the following contributions: 1) we propose that volume-based incentive schemes in P2P systems unnecessarily punish slow peers and decrease overall

We also consider how TT affects countries ’ non-cooperative choices of permit endowments and find that it reduces overall emissions. Finally, a simple numerical

Darmstadt, den 28th February 2014 (Denis Lapiner) This Master’s Thesis proposes and implements a game design for an Android based massively multiplayer online augmented reality game. The proposed game design is based on an analysis of other popular aug-mented reality games such as Ingress, a game created by Google Inc. The game of this thesis motivates the players to meet in the real world and move in groups to certain points of interest like historic mon-uments. The spatial locality of players, which comes up when players move in groups, makes the game interesting for the research on mobile ad hoc networks (MANETs). The provided implementation of the game contains a centralized communication component that logs the network communication between players and therefore, is usable for data collection of network traffic in MANETs. The collected data

Massively multiplayer online games (MMOGs) have become increasingly popular in the recent years, particularly in the form of online role-playing games (MMORPGs). These games support up to several ten thousand players interacting in a virtual game world. The current commercially successful games
