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

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable reliable, low-cost monitoring of migratory species. The developed multi-tier architecture yields ecologists with unconventional behavior in-formation not furnished by alternative tracking systems at such a large scale and for a low-cost. The simulation, development and implementation of the CraneTracker soft-ware system is presented. The system is shown effective through multiple proxy deploy-

I would like to thank Prof. Dr. Torsten Braun, head of the Computer Network and Distributed Systems group (RVS), for supervising this work and for his insightful advises. Prof. Dr. Torsten Braun encouraged and motivated me to publish my research results and he provided me the opportunity to present the work on various conferences, for which I thank him. I would also like to thank Prof. Dr. Roger Wattenhofer, responsible for the Koreferat of this work. Also, Prof. Dr. Oscar Nierstrasz who was willing to be the co-examinator of this work deserves many thanks. Many thanks go to my colleagues of the RVS group and of the IAM for our various interesting discussions about all kinds of topics and for making the institute a very pleasant and friendly place to work at. Special thanks go to David Steiner, Marc Steinemann, Matthias Scheidegger, Florian Baumgartner, Ruy De Oliveira, and Attila Weyland. There are many students who worked with me and helped a lot in developing and implementing. Among them I especially thankful to Thomas Bernoulli,
