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...

abstract service quality has been an area of interest of both researchers and practitioners in recent years. in light of such interest, two distinctive schools have contributed to service quality and customer satisfaction. the first school focuses on the role of organizations and their staff as the origin of service quality improvement while the second one incorporates customer’s participation ...
