In this demo we introduce X-MANO, a cross- domain network service orchestration framework consisting in an inter-domain confidentially-presenting federation interface and in an information model for multi-domain network service life-cycle programmability. X-MANO is effectively deployment- agnostic and can be used in hierarchical, peer-to-peer and cascading (or recursive) configuration. During this...
In the recent years several proprietary as well as open-source frameworks for network service orchestration have emerged. Similarly a significant body of literature has been produced investigating both the theoretical and practical aspects of network service orchestration. Nevertheless, currently available frameworks for network service orchestration are designed under the assumption that they can...
The orchestration of network services is a well investigated problem. Standards and recommendation have been produced by ETSI and IETF while a significant body of scientific literature can be found exploring both the theoretical and practical aspects of the problem. Likewise several open-source as well as proprietary tools for network service orchestration are already available. Nevertheless, in most...
In this paper we study 3GPP mobility robustness in the context of Public Safety (PS) communications. In specific, we investigate the scenario in which 4G LTE connectivity is provisioned by means of Aerial evolved Node Bs (AeNBs) mounted on Low Altitude Platforms (LAPs) raised in the sky at an altitude ranging from few hundreds meters to one kilometer. Given the peculiarities of PS communications,...
Public safety networks are receiving more attention and priority in the several countries as the state authorities deal with unsuspected situations and natural disasters. Heterogeneous wireless networks with wireless devices supporting multitude of radio access technologies are witnessing increasing interest from public safety consumers. Energy efficiency in such networks has become an important design...
Past years have witnessed the surge of mobile broadband Internet traffic due to the broad adoption of a number of major technical advances in new wireless technologies and consumer electronics. In this respect, mobile networks have greatly increased their availability to meet the exponentially growing capacity demand of modern mobile applications and services. The upcoming scenario in the near future...
In this paper, we investigate scenarios where 4G LTE base stations are mounted on balloons raised in the sky for the provision of cellular connectivity and coverage within an area of few kilometers (e.g., scenarios for emergency communications). In this context, the link between the base stations need to be completed using wireless technologies, thus impacting the performance of the X2 logical interface...
The UMTS Long Term Evolution (LTE) is the latest and most advanced cellular technology that is coming to market. As LTE and its advanced version promise unprecedented peak data rates both in uplink and downlink, they seem to represent a striking solution for many fields requiring mobile broadband access. Nowadays, one area that is strongly emerging is represented by public safety communications. In...
Energy efficiency in wireless networks has become an important field of research due to ever increasing energy expenditure in battery supplied mobile terminals. In this paper we present an energy efficient routing scheme for multi-standard infrastructure wireless networks based on multi-hop cooperative relaying. The aim of the proposed technique is to exploit short-range cooperation to take benefit...
Managing the power resource in battery operated wireless devices is very crucial for extending the lifetime, here we propose the concept of power trading in wireless communications. We present a business model using sealed bid procurement auction based game theory for power-trading in cooperative wireless communication with quality of service (QoS) constraints. We formulate the problem as an auction...
We propose hitting set heuristic for regenerator sites selection considering multiple paths to provide any-to-any protected connectivity. The results indicate that parameters do not have impact for small networks for path trails greater than two.
In translucent optical networks, the signal will remain in the optical domain as long as possible and will be regenerated only when its quality falls below a threshold or a wavelength contention has to be resolved. In these networks a limited number of regenerators are placed at a selected set of nodes. As OEO regenerators are expensive, the problem of regenerator site selection is of paramount importance...
We propose a framework for regenerator sites selection based on multiple paths which can easily be extended to include several important features required by operators and discuss the initial results obtained from extensive simulation experiments.
We study single path-based heuristics with ranking and redirection, and connectivity dependent heuristics based on k-center and connected dominating set problems, for regenerator site selection to provide any-to-any connectivity in reconfigurable translucent optical networks.
