A Hyper Cellular Architecture and its Software-defined Implementation for 5G Mobile Communications

Zhisheng Niu

Electronic Engineering Department, Tsinghua University

Tsinghua National Lab for Information Science and Technology

Abstract: Cellular concept was invented to improve the spectrum efficiency by spectrum reuse and has contributed a lot for the explosive deployment of today’s mobile communication industry.  As mobile data and video traffic is fast growing, the next-generation mobile communication (5G) networks are expected to further provide 10-fold more capacity than 4G mobile networks with the limited spectrum as well as energy resources.  To deal with this challenge, the traditional physical- and MAC-layer capacity-enhancement approaches are no more sufficient and efficient.  A system- or network-level approach is needed, including rethinking about the existing cellular structure.  On the other hand, cellular networks are transforming from just a mobile communication platform to a smart information infrastructure on which more and more always-online type of traffic (e.g., short but frequent signaling packets of various social networks, sensing information of smart earth and smart community, control packets in cooperative heterogeneous wireless networks) need to be handled in an energy-efficient way.  As a result, the existing cellular framework should be revisited.

In this talk, we propose a new cellular framework, named hyper-cellular arcitecture (HCA), aiming at increasing the whole network capacity by more than 10-fold based on the existing limited spectrum and energy resources as well as accommodating ever-increasing always-online traffic in a more energy-efficient way.  The key idea here is to separate the coverage of control signals from the coverage of data signals so that the data coverage can be more elastic in accordance with the dynamics of traffic needs and QoS requirements.  This can be considered as the further extension of the existing C-RAN concept and one of the key candidate technologies for 5G mobile communications systems.  Some preliminary results have shown that this new paradigm has a great potential in the capacity enhancement and energy savings.  Its software-defined implementation through the convergence of virtual BS and edge cloud technologies will also be discussed.

Online Social Network Data Placement over Geo-Distributed Clouds

 Lei Jiao

Researcher with Bell Labs Ireland

Abstract:

Online social networks (or more generally, socially aware services) are online services where users build social relationships and interact with one another. With a large user base, a socially aware service often needs users’ data to be partitioned and replicated across multiple geo-distributed clouds. Choosing at which cloud to place which user’s data, however, is difficult, as an effective data placement must achieve various system objectives while facing critical challenges such as the interconnection of users, the master-slave data replication, the conflicting requirements of different objectives, and the diversity of multi-cloud data access policies.

In this talk, we present our recent work on placing data of socially aware services across geo-distributed clouds. We investigate two problem settings. In the first setting, we optimize the service provider’s monetary expense of using cloud resources, while guaranteeing the service quality and the data availability by ensuring data of interconnected users are always co-located at a common cloud. In the second setting, we optimize system objectives of multiple dimensions simultaneously, e.g., the carbon footprint, the service quality, the inter-cloud traffic, as well as the reconfiguration cost incurred by changing one data placement to another. Both problems are large-scale discrete, combinatorial optimization problems that are hard to solve. Having the model formulations, our core contributions are the algorithms that could solve the two problems: for the first problem, our approach is based on the observation that swapping the roles, either master or slave, of a user’s data replicas at different clouds not only leads to possible cost reduction, but also maintains service quality and data availability; for the second problem, we propose to decompose it into two subproblems of placing master replicas and slave replicas respectively, where we leverage the graph cuts technique to solve the master placement problem, use a greedy method to place the slaves, and solve the two subproblems alternately in multiple rounds. Extensive evaluations with real-world large-scale data traces demonstrate that, compared with the state of the art and de facto methods, our approaches have substantial advantages in saving monetary expense and optimizing multiple objectives. We further analyze and discuss related issues such as complexity, optimality, scalability, and design alternatives, if time permits.

The Supramolecular Chemistry Ireland (SCI) Half Day Symposium was held at Renehan Hall, Maynooth University on Wednesday 8th July 2015 from 2pm to 6.00 pm with a Poster and Wine Reception.

SCI 2015 has brought together a host of world renowned participants ranging from invited speakers to flash presentation sessions and a poster session covering a broad range of supramolecular topics. Coinciding with The Catalysis and Sensing for our Environment Symposium (CASE) 2015 taking place in Dublin, SCI2015 has combined the best of Supramolecular Chemistry research from China to Ireland/UK and everywhere in between, opening lines of communication and collaboration worldwide.

Supramolecular Chemistry is all about interactions between molecules: how they can recognise each other, assemble and function on a molecular scale. It provides a bottom up approach to nanoscale systems with applications ranging from biology to materials science.

The Supramolecular Chemistry Symposium in Ireland has been held annually since 2000 in the School of Chemistry, Trinity College Dublin. This is the first time it has been held outside of TCD.

It is the largest meeting of its kind in Ireland and brings together supramolecular chemists with interests in organic, inorganic, physical and biological chemistry from across Ireland stretching to China and Australia.

In addition to the objective to stimulate and catalyse strong participation by Irish researchers in H2020, the objectives of the 2015 IvP call will be similar to those of previous calls. These include:

• To support excellent scientific research that has potential economic and societal impact.
• To increase the average research income secured by Ireland-based PIs from international funding entities such as the EU.
• To increase the level of leadership roles held by Ireland-based PIs in major European Initiatives, in particular Horizon 2020.
• To maintain Ireland’s top 20 position in international bibliometric rankings through an increase in the number and quality of journal publications.
• To support through the Investigator Career Award (ICA) Programme those researchers returning to active academic research after a prolonged absence.
• To foster and support collaborations with significant research entities and industry.

The funding available and the award durations will be similar to the IvP 2014 call (4-5 year research programmes with budgets ranging from €400,000 to €2,500,000).

The call will launch in late March 2015 with a deadline in late June 2015.
