With the growth of Internet users' traffic demands, the efficient and cost-effective usage of
bandwidth and spectrum in optical networks plays an important role in improving service …

Cloud-fog computing emerges to satisfy the low latency and high computation requirements
of Internet of Things (IoT) services. Elastic optical networks (EONs) are excellent substrate …

As the services in elastic optical networks (EONs) are bandwidth-intensive, unpredictable
and dynamic, increasing network factors are emerging to affect the performance of network …

In this paper, we formulate an integer linear programming (ILP) to perform multicast routing
and spectrum assignment (MRSA) in elastic optical networks, which serves jointly a set of …

With the expanding of its scale and the energy cost factors being ignored in green cloud
computing, the problem of high energy cost and low efficiency is exposed. Based on the …

The aim of the study is to explore the intellectual structure of the field and fronts in research
on energy efficiency in the context of cloud computing and thus to contribute to science …

The spectrum efficiency is a greatly important issue when we establish connection requests
in elastic optical data center networks (EODCNs). In this article, we address the spectrum …

We investigate the problem of energy-efficient resource allocation constrained to quality of
service and physical requirements in orthogonal frequency division multiplexing (OFDM) …

To meet the requirements of the emerging applications, future networks must transmit
multiple class of services traffic with diverse quality of service (QoS) requirements. In this …

Elastic optical networks (EONs) are increasingly used to interconnect data centers. As
interdatacenter traffic is expected to continue to grow at high rates for the foreseeable future …
