Mobile Big Data Managing, Mining and Modeling (MBD-M3)
By focusing on characterizing the mobile traffic, web accessing, and information usage traces based on large-scale and long-time mobile big data, which is collected from the commercial mobile operator with 380 thousand base stations and 15 million users spanning over a year from 15 major cities of China, we qualitatively visualize and quantitatively characterize the spatio-temporal human behaviors in the physical-cyber system including mobility regularity, traffic consumption patterns, social friendship activity, online information and commodity consumption, etc. Based on these fundamental findings and credible models, we further investigate how to utilize these important insights on how to deal with the problems encountered with the current mobile networks including traffic congestion offloading, green communications, solidified architecture, etc. Specific techniques include Hadoop/spark programming, machine learning, big data mining and processing algorithms of clustering, classification, graphing, etc.
Social-Aware Next Generation Mobile Networks (SAN-5G)
Aiming to establish a new paradigm to solve the problem of universal resource allocations for next generation mobile networks (5G), this project investigates a social behavior aware optimization framework that couples the social layer of human behaviors with physical layer of wireless communications. First, we model the mobility pattern and social behavior for users through mining the big data, which contains the location information, traffic consumption, service access, etc. Then, we establish social behavior aware optimization theory framework for mobile cellular networks based on the profound understanding of the interplay between social behavior and universal resource allocations. Finally, for typical social service scenarios, we evaluate the system performances through quantitative analysis and quantitative gains, which demonstrates the effectiveness of social behavior aware for network optimization framework and corresponding mechanisms and methods. Specific techniques involving this project include networking system modeling, social big data analysis, optimization and game theory, etc.
Software-Defined Next Generation Networks (SDN-5G)
Software defined network (SDN), an innovative paradigm for future networks, advocates separating the control plane and data plane, and abstracting the control functions of the network into a logically centralized control plane. Aiming to establish a new paradigm for 5G mobile networks, software-defined 5G mobile networks extend the concept of SDN controller to take the control functions of the physical layer into consideration as well, not just those of the network layer. By abstracting the control functions of access and core networks jointly, a logically centralized programmable control plane achieves the fine-grained controlling and flexible programmability, which is capable of achieving the design goals of convergence of heterogeneous networks, fine-grained controllability, efficient programmability for network evolution, and network and service customizability. We investigate this project by both system and theoretical approach. Specific techniques include cloud computing system (OpenStack, Neutron), SDN components (Floodlight, ODL, OVS), mobile core network elements, practical network optimization and system prototype.
