With the miniaturization of computing, communication and sensing devices, distributed real-time systems consisting of sensors or teams of autonomous mobile units, are becoming increasingly attractive for a wide range of applications, including homeland security, environment monitoring (e.g., pollution detection), or even assisted living.                                                                              

In real-time applications (like surveillance and hazard detection), timeliness and robustness become critical properties in particular when the distributed nodes are wireless, mobile, and the system is subject to node/network failures. In fact, unpredictable changes of the environment that a real-time team has to interact with, can trigger transient losses of connectivity.     

Innovative approaches for cluster based RT wireless communication (like "RI-EDF") and ad-hoc multi-hop wireless communication (like "Real-Time Chains") will be presented, which were developed to address some of the challenges (i.e., temporal predictability, robustness, available throughput) faced by real-time ad-hoc networks of embedded systems. These techniques allow us to effectively enhance network performance, while still maintaining timeliness.
