The rising number of mobile devices and their increasing computational capabilities enable new interactive context-sensitive applications.
Popular examples are augmented reality games such as Google's Ingress, where users interact with each other in the real world while being part of the game at the same time. In the first half of the talk, we discuss an event dissemination system that exploits the locality characteristics of mobile augmented reality games to (i) enable and configure local peer-to-peer dissemination of events when appropriate and (ii) reconfigure or replace the utilized peer-to-peer protocol to adapt to a wide range of requirements.
Evaluation results suggest the need for dynamic monitoring in such systems to resolve local configuration conflicts without adding to much complexity to the server side. To this end, Nils presents the adaptive monitoring system "Crater" in the second half of the talk.
Monitoring is crucial in mobile networks to ensure reliable and efficient operation. Current monitoring mechanisms mostly rely on a static architecture and exhibit problems to handle the changes of mobile networks and environmental conditions over time. In the second half of the talk, an adaptive monitoring mechanism is presented which overcomes these limitations. The mechanism exploits the connectivity and resource characteristics of mobile communication devices to (i) reconfigure its monitoring topology and (ii) adapt to changes of mobile networks and environmental conditions.
Finally, a brief overview of the utilized and publicly available "Simonstrator Platform" for combined development of simulation models and prototypes for mobile applications as successor to the PeerfactSim.KOM overlay simulator is given.
About Nils Richerzhagen
Beginning in 2009 Nils studied Electrical Engineering and Information Technology at TU Darmstadt with a major in Computer Engineering. As a student assistant, working with Professor Dr. Silvia Santini, he focused on protocol design for and performance evaluations of wireless sensor networks with a direction to mobile ad hoc networks (MANETs).
In his studies Nils targeted networking systems and communication technologies for distributed systems. In 2014 Nils obtained his Master's degree with the thesis "Adaptive Monitoring for Mobile Networks in Challenged Environments".
Starting in 2015, he is PhD student at Multimedia Communications Lab (KOM) at the Technische Universität Darmstadt, where he is member of the collaborative research centre MAKI. His research interest focuses on distributed systems and adaptive overlays with monitoring background.
About Björn Richerzhagen
Björn studied Electrical Engineering and Information Technology at TU Darmstadt since 2007, with a major in Computer Engineering (Datentechnik). In 2012, he obtained his Master's degree with the thesis "Supporting Transitions in Peer-to-Peer Video Streaming". During his studies, he focused on distributed software systems and network technologies, especially in the context of mobile devices. As a student assistant, he participated in the design and development of Peer-to-Peer overlays for information dissemination and location based search [GSR+12] as well as in the development of new components for the simulator PeerfactSim.KOM.
Currently, he is PhD student at Multimedia Communications Lab (KOM) at the department of Electrical Engineering and Information Technology of the Technische Universität Darmstadt. His research interests are centered around distributed systems and adaptive communication protocols. He is a member of the collaborative research centre MAKI, working within project area C02 on adaptive publish/subscribe systems for mobile applications.
