In this paper, we introduce the implementation ofthe Sporadic Server algorithm at the user level in Real TimeJava. That is, we do not modify the specification of the JavaVirtual Machine (JVM) so our proposal runs without problemson every JVM with support for real-time scheduling. The paperin- cludes an experimental evaluation of the aperiodic handlingmechanism using as benchmark the one developed...
In this paper, a real-time analysis of opportunistic networks is done. The worst case end-to-end delay is presented when there are special nodesnamed mules that are periodic and follow a fixed and known path. Necessaryand sufficient conditions for the schedulability of the system are presented sodeadlines can be guaranteed.
VHF radio systems commonly used to support search and rescue activities after disasters limit the flow of information among response teams deployed in the field. It generates islands of information that jeopardizes the coordination and effectiveness of the response activities. This article proposes a communication model that uses opportunistic networks and real-time messages delivery to help address...
