The routing problems can be divided into two major classes. They are 1) Unicast routing and 2) Multicast routing. The Unicast routing problem is as follows. Given a source node sr, a destination node dn, a set of QoS constraints qc and an optimization goal (optional), find the best feasible path from sr to dn, which satisfies qc. The Multicast routing problem is as follows. Given a source node ...

This work explores energy as a parameter for Quality of Service (QoS) of embedded systems. We argue that it is not enough to guarantee other QoS metrics (e.g., processing, communication, memory) if doing so the system runs out of battery and is unable to complete its computations. In this context, we developed a scheduler for imprecise tasks that, knowing battery’s life-time and tasks’ energy c...

The so-called RoboGuard is a mobile security device which is tightly integrated into the existing surveillance framework developed and marketed by Quadrox, a Belgian SME. RoboGuards are semi-autonomous mobile robots providing video streams via wireless Intranetconnections to existing watchguard systems, supplemented by various basic and optional behaviors. RoboGuards fill several market-niches....
