Small cell networks are currently seen as a new way to satisfy the increasing wireless traffic demand. The proximity of base stations to subscribers brings many possibilities for the development of new applications, including new offerings based on cloud computing. Smartphones can directly offload applications to close base stations, provided that these are equipped with additional computational and...
Offloading to external surrogate machines (part of) the workload generated by applications running on mobile nodes has been suggested as a way to improve the mobile user experience. In this paper, we consider a set of mobile users that can offload their computation on Virtual Machines (VMs) instantiated in a cloud infrastructure implemented over a set of femtocells which have been augmented with computational...
Nowadays, heterogeneous networks are seen as a key enabler to meet the challenging performance required for the evolution of LTE networks. At the same time, cloud computing is an emerging trend that outsources computing and storage resources, and extends mobile handsets capability of processing large data amounts. Cooperation in heterogeneous networks allows better (improved) network management by...
This paper shows how to improve the overall network performance (cell throughput, fairness, and energy efficiency) via centralized coordination of LTE-A cells. We first present optimization models for small-scale coordination (i.e., three cells). Then, we show that extending the same solution to a higher number of cells is generally unfeasible, due to both an unfeasible amount of reporting on the...
In the present study self-backhauled small cells for LTE-Advanced (a particular kind of small cells with wireless backhauling) are analyzed from the energy efficiency point of view. We perform an assessment of system performances with respect to traditional homogeneous LTE-Advanced networks, not only in terms of capacity and energy consumption, but also showing the potential impacts on the Quality...
