In this paper, we elucidate the main performance bottleneck in realizing packet processing which require carrier-scale huge tables to lookup (carrier-scale packet processing) on top of general-purpose servers. Our experimental quantitative analysis using DPDK-Click based packet processing model reveals that performance degradation of the carrier-scale packet processing is mainly caused by increased CPU cache misses with increasing number of input traffic flows. This indicates that the main performance bottleneck of carrier-scale packet processing using general-purpose hardware is the lack of memory response performance. As a solution to the bottleneck, we propose novel server architecture that utilizes Hybrid Memory Cube (HMC), a sort of 3D-stacked DRAM, to reinforce memory response performance in terms of concurrency. Our simulation based evaluation shows that our proposed server architecture can realize more than 40 Gbps carrier-scale packet processing without any dedicated hardware. Our work shows that augmented concurrency of memory response is as important as parallel processing at multi-core CPU to improve the system level performance of carrier-scale packet processing using general-purpose hardware.

In brainstorming for ways to exploit Internet of Things (IoT) security, we envisioned the following premise: an attack which compromises the security of multiple wireless interfaces. In this project, we attempt to reveal information about a region of networks; this data includes each network's location, security, signal strength, and user activity. In exposing such data, we hope to shed light on the security problems associated with wireless networks.

Small cells have been proposed to improve the signal quality of cell edge users and enhance the serving coverage. But a large number of small cells will cause severe interference and high energy consumption. Hence, green communication is an important issue. The main contribution of this paper is to provide an interference-aware small cell on/off mechanism in a downlink heterogeneous network system to reduce inter-cell interference in the sense of energy saving. Two criteria for the small cell on/off mechanism are proposed; one is based on the generated interference (GI) and the other is based on the signal to generated interference ratio (SGIR). In addition, two selection rules are provided; one is the exhaustive search (ES) method and the other is the one time (OT) method. In hyper dense small cells deployment scenario, our interference-aware small cell on/off mechanism can efficiently reduce inter-cell interference to maximize the total network energy efficiency. Compare to the traditional UE-cell association approach, our method provide 47.38% improvement at λb/λu = 0.4 and 61.44% improvement at λb/λu = 0.6.

In this paper, we discuss a method to construct a radio environment map (REM) in an environment with multiple primary users (PUs). The REM provides statistical information about the PU activity at each location. It enables the secondary user to access the licensed band dynamically. We derive the measurement architecture based on the “crowd-sourcing” scheme to gather large-scale measurement data with inexpensive sensor nodes. The PU detection or identification scheme is key part of the REM construction then there are multiple PUs in the environment. However, it is difficult to identify multiple PUs in an individual user terminal. Therefore, the PU detection or identification problem is solved at the REM servers using the Hidden Markov Model (HMM), which is a time-series-based machine learning technique. The proposed HMM method classifies the measurement data depending on the combined state of each transmitter, which can be either active or idle. The results show that the proposed method exhibits better performance than the existing unsupervised clustering method.

To reduce the transmission power while maintaining quality of service requirements of users, more remote radio heads (RRHs) should be active, and this in turn increases the circuit power in the distributed antenna systems with simultaneous wireless information and power transferring. Yet, the above procedures may lead to an unbalanced power consumption between transmission and circuit; therefore causes extra burden on the operators' power budget. To obtain a balanced transmission power and circuit power, this paper studies the system utility minimization problem in such a system via joint RRH selection and beamforming. The utility is formulated as the weighted sum of transmission power and circuit power. Since the formulated problem is NP-hard, a low complexity iterative algorithm is developed to achieve a near-optimal solution. The complexity of each iteration step is analyzed. Computer simulation results show the convergence of the proposed algorithm and the tradeoff between the transmission power and the circuit power.

Recently, an enormous increasing number of mobile devices have changed people's life and brought huge demands for services. D2D (Device-to-Device) communication is a brand-new fashion that allows mobile stations communicating directly with each other using existing licensed band without traversing through core network, and thereby offload traffic from base stations (BS). On the other hand, relays are indispensable to the next generations of mobile communication networks. Relays can remove the coverage holes, increase system capacity, expand the coverage area of base stations and enhance transmission rate for the devices in cell edge, and thereby it also provides uniform data rate coverage in the cellular networks. This paper proposes a model that integrates the advantages of relay and D2D and proposes a method that can improve spectrum efficiency and decrease path loss or shadow fading which makes worse communication in the system. This paper also proposes a way how to choose a better relay and it can increase the system throughput. Simulation results of uplink and D2D communication show that the proposed method can increase the system throughput.

Brain Computer Interfaces (BCIs) stand as a promising new technology to enrich interaction with objects in both the physical and virtual world. As BCI technology continues to mature for possibly becoming a essential part of the future communication and interaction with people and objects, more attention is needed for effectively and accurately authenticating the very user of the input device. We attempt to analyze and improve current and new methods of user authentication that can be provided through consumer-grade BCIs. We first propose a new neurological framework for an authentication system integrated with BCIs. We then evaluate the effectiveness of the framework in conjunction with the fidelity and usability of electroencephalogram (EEG) data obtained from a consumer-grade BCI to analyze different types of sensory pass-thoughts and their effectiveness among individuals. Preliminary results show that the proposed framework is promising to improve the accuracy of neurological user authentication.

Media streaming is the most rapid-growth network service and occupies most of traffics on Internet. This paper presents approaches for enhancing the network performance for media streaming in two aspects. Firstly, in order to improve the network performance of a media server executing on a Virtual Machine (VM), a network framework using Software-Defined Networking (SDN) is introduced. This framework integrates the Kernel-based VM with OpenFlow switch to address the issue of virtualization overhead. The experimental results show that this scheme improves network performance by 68% compared to the conventional structure. Furthermore, for maintaining the quality of Scalable Video Coding (SVC) media streaming during the transmission, a novel routing algorithm based on SDN is illustrated. This algorithm jointly considers bandwidth, delay, and packet loss and automatically deploys routes for different layers in SVC streaming. Comparing to conventional methods, this algorithm reduces the packet loss rate by more than 10% and improves the quality of the received Video sequence.

Tactical networks are generally simple ad-hoc networks in design, however, this simple design often gets complicated, when heterogeneous wireless technologies have to work together to enable seamless multi-hop communications across multiple sessions. In recent years, there has been some significant advances in computational, radio, localization, and networking te, and session's rate i.e., aggregate capacity averaged over a 4-time-slot frame)chnologies, which motivate a clean slate design of the control plane for multi-hop tactical wireless networks. In this paper, we develop a global network optimization framework, which characterizes the control plane for multi-hop wireless tactical networks. This framework abstracts the underlying complexity of tactical wireless networks and orchestrates the the control plane functions. Specifically, we develop a cross-layer optimization framework, which characterizes the interaction between the physical, link, and network layers. By applying the framework to a throughput maximization problem, we show how the proposed framework can be utilized to solve a broad range of wireless multi-hop tactical networking problems.

In massive MIMO systems, multiple high-speed high-resolution ADCs will be a major obstacle for real applications because of the hardware complexity and power consumption. One solution to this problem is to adopt low-cost low-resolution ADCs instead. Note that highly quantized signals will destroy the orthogonality of OFDM design, the key point remains to find computational decoding methods while maintaining acceptable performances. To address this issue, we develop a low complexity algorithm designed for low-resolution ADCs RF-frontend using iterative decoding based on Approximate-Message-Passing (AMP). The proposed algorithms can provide adequate performance in low-resolution ADC systems compared to approximate LMMSE solution.
