Title: MobilityFirst Architecture Considerations for 5G

Speaker: Yanyong Zhang


This talk presents an overview of 5G considerations behind the design of the MobilityFirst future Internet architecture. The MobilityFirst architecture is motivated by a historic shift of the Internet from the fixed host-server model to one in which access from mobile platforms becomes the norm. This implies the need for a future Internet protocol stack designed to handle the special needs of mobility services efficiently and at large scale. A number of key 5G requirements, including user/network mobility, varying wireless link quality and disconnection, multi-homing, ad hoc networking, flexible autonomous system boundaries, and spectrum coordination are identified along with a brief discussion of their implications for protocol design. This is followed by a summary of the MobilityFirst protocol design based on separation of names and locators, global name resolution service, storage-aware routing with hop-by-hop transport, integrated spectrum management, along with an edge-aware inter-domain routing framework. Illustrative examples showing how the MobilityFirst protocol stack supports mobility, multi-homing, and inter-network spectrum coordination are also given.

Title: Cell-Edge-Aware Precoding for Downlink Massive MIMO Cellular Networks

Speaker: Tony Q. S. Quek


We propose a cell-edge-aware (CEA) zero forcing (ZF) precoder that exploits the excess spatial degrees of freedom provided by a large number of base station (BS) antennas to suppress inter-cell interference at the most vulnerable user equipments (UEs). We evaluate the downlink performance of CEA-ZF, as well as that of a conventional cell-edge-unaware (CEU) ZF precoder in a network with random base station topology. Our analysis and simulations show that the proposed CEA-ZF precoder outperforms CEU-ZF precoding in terms of (i) aggregate per-cell data rate, (ii) coverage probability, and (iii) 95%-likely, or edge user, rate. This result identifies CEA-ZF as a more effective precoding scheme for massive MIMO cellular networks. Our framework also reveals the importance of scheduling the optimal number of UEs per BS, and confirms the necessity to control the amount of pilot contamination received during the channel estimation phase.

Title: Towards Information Privacy for the Internet of Things

Speaker: Wee Peng Tay


In an Internet of Things network, multiple sensors send information to a fusion center for it to infer about a public hypothesis of interest. However, the same sensor information may be used by the fusion center to make inferences of a private nature that the sensors wish to protect. To model this, we adopt a decentralized hypothesis testing framework with binary public and private hypotheses. Each sensor makes a private observation and utilizes a local sensor decision rule to summarize that observation before sending to the fusion center. We adopt a nonparametric approach to design local sensor decision rules that allow the fusion center to detect a public hypothesis with minimal regularized empirical risk,

while keeping the empirical risk of detecting the private hypothesis above a privacy threshold. We develop iterative optimization algorithms to determine an appropriate privacy threshold and the best sensor local decision rules, and show that they converge. Numerical results on both synthetic and real data sets suggest that our proposed approach yields low error rates for inferring the public hypothesis, but high error rates for detecting the private hypothesis.
