Abstract

With the miniaturization of computing, communication and sensor devices, distributed real-time systems consisting of teams of autonomous mobile units, are becoming increasingly attractive for a wide range of applications, from homeland security to environment monitoring (e.g., pollution detection).

In critical applications (like surveillance and hazard detection), timeliness and robustness become critical issues in particular when the system is subject to dynamic workloads and node/network failures. In fact, unpredictable changes of the environment that a real-time team has to interact with, trigger different nodes' action causing dynamic workloads and/or transient losses of connettivity.

Two innovative approaches, called "FAI-EDF" and "Bandwidth Sharing" (BASH) will be presented, which have been developed to address the new challenges (i.e., temporal predictability, robustness, dynamic workloads) faced by collaborative real-time systems. These approaches allow us to effectively and efficiently maximize network and CPU performance, while still providing real-time guarantee.
