Visible light communication (VLC) is envisioned as a core component of future wireless networks due to, among others, the huge unlicensed bandwidth it offers and fact that does not cause any interference to existing radio frequency (RF) systems. In order take advantage both RF VLC, most research on their coexistence has focused hybrid designs where data transmission user could originate from ei...

Fast IT development combined with diverse range of requests for IT services have led to the establishment of huge energy hungry data centers all around the world. Consolidation is proposed as one of the most effective methods for energy saving in modern cloud data centers. This paper addresses multi target resource allocation for cloud data centers that applies a holistic view to the resource a...

Moreover, the data traffic is also more among users. So we ...

Energy efficiency has become an important measurement of scheduling algorithms in virtualized data centers. One of the challenges of energy-efficient scheduling algorithms, however, is the trade-off between minimizing energy consumption and satisfying quality of service (e.g. performance, resource availability on time for reservation requests). We consider resource needs in the context of virtu...

We consider Markov Decision Processes (MDPs) with mean-payoff parity and energy parity objectives. In system design, the parity objective is used to encode ω-regular specifications, and the mean-payoff and energy objectives can be used to model quantitative resource constraints. The energy condition requires that the resource level never drops below 0, and the mean-payoff condition requires tha...
