Abstract: Future mobile applications will increasingly rely on direct communication among devices or with the environment—e.g., sensors—to provide interactive experiences to their users. The resulting communication characteristics are highly dynamic due to mobility and social behavior of humans, requiring applications to continuously adapt to the prevailing conditions. To this end, they require accurate information about the current state of the network. This information is obtained by monitoring mechanisms. Current mechanisms, however, are limited in their applicability in such a dynamic scenario, given that they only perform well for a limited range of environmental conditions. In this work, we perform an in-depth analysis of these limitations. We propose a monitoring service that executes transitions between individual state-of-the-art monitoring mechanisms to adapt its operation to dynamic network conditions. We evaluate a prototype of the transition-enabled monitoring service to study the impact of transition execution on the performance of continuous monitoring. Our results indicate that the achieved recall can be more than doubled while the latency can be reduced in the order of magnitudes compared to state-of-the-art monitoring approaches.
