The goal of the MONET department is to increase the flexibility whilst optimizing the performance of future heterogeneous and dynamic (wireless) networks by combining cloud computing, data networking and mobile networking design principles. This includes the integration of software-defined networking and network functions virtualization in the RAN, backhaul, and core towards a programmable, self-organized, and energy efficient network operation.
This goal is achieved by working on three main research lines: i) elastic mobile networks, which includes software-defined mobile networks and network resource virtualization, ii) big data for mobile networks, dealing with self-organized networks and cognitive network optimization, as well as the exploitation of network-level information to optimize processes external to the network, such those of a city or utility grids, and iii) sustainable mobile networks, which include energy efficient algorithms and nearly-zero energy networks that exploit harvested energy.
At the methodological level, two main tools are being developed by the MONET department. The open source ns-3 simulator is not only used as simulator, but also as emulator in our experimental proof-of-concepts. More specifically, the LTE network simulator/emulator (LENA), which has become the de facto standard in the research community for LTE simulations, also provides an LTE protocol stack for our experimental evaluations. The experimental work of the department is carried out over the EXTREME Testbed®, an SDN/NFV-based experimental framework for the evaluation of mobile network services, featuring a number of generic computing, storage, and networking elements to evaluate a wide range of scenarios of interest.Scientific Publications & Patents
