Current Project: How Fast is NFSv4.1 -- A Benchmark Study of the Linux NFSv4.1
We present a benchmarking study of Linux’s implementation of NFSv4.1, the latest version of the NFS protocol. The NFSv4.1 servers in the 2.6.32 and 3.12.0 kernels performed well in most of our experiments. However, we also observed that Linux’s memory management can waste up to 80% of NFS I/O throughput. NFS performance also suffers from unfair networking behavior that causes the throughputs of identical NFS clients to differ by a factor up to 19×. We show that NFS delegations can boost performance by saving up to 90% of network traffic, but a delegation conflict can cause a delay of at least 100ms—more than 500× the RTT of our 1GbE network. We also found that NFS can exhibit counterintuitive performance behavior due to its intricate interactions with networking and with journaling in local file systems.
DATA Lab, CS 2207
Professor Leman Akoglu, Department of Computer Science
Student: Shebuti Rayana
Our group is interested in studying, understanding, and modeling large-scale data. We focus on problems involving massive graphs (GATA); including link analysis, pattern discovery, and outlier/anomaly/fraud/event/outbreak detection. Our goal is to develop algorithms and scalable analytics for mining & learning from (graph) data.
Current Project: An Ensemble Approach for Event Detection and Characterization in Dynamic Networks.
Event detection in temporal graphs, such as cyber and communication network traffic data, has many key applications in systems monitoring and security. It also has useful applications in detecting real life events from news corpus, email communications, cell phone communications and so on. Dynamically monitoring the network over time to detect suspicious changes in its structure and behavior is a challenging task due to the evolving nature of the data. In this work, we develop an ensemble approach for real-time event detection and characterization for dynamic graphs. We propose to use five detection techniques that can rank the time points by their anomalousness, the results of which we combine to come up with a final ranking. What is more, we characterize the events; by identifying the main network entities, i.e. specific nodes and edges, that are responsible for the detected changes the most. Our ensemble also employs a rank merging strategy to rank these entities by the magnitude of their suspiciousness. There are two key features of our approach: (1) it is designed to operate in a real-time fashion, where the decisions are made as new data arrives, and (2) the ensemble approach yields a better ranking, thanks to its voting mechanism. We use both simulated data (network flow) and real data (New York Times news corpus and email communication of Enron Inc.) for our experiments. At first experiments are performed on cyber network flow data, carefully simulated at a large corporation with ground truth events. Our proposed method has successfully identified the time points in which the network went through suspicious state changes, as well as the key network agents that instantiated these changes which are verified quantitatively. Experiments on New York Times news corpus in the setting of temporal graphs with co-occurrence of named entities in the same article and also on email communication network of Enron Inc. successfully identified some important real life events and the entities associated with those events.

Current Project: RFID Sense-a-Tags for the Internet of Things
We aim at addressing the question if it is feasible to design backscattering devices that can communicate independently. We investigate the design of a novel component for the Internet of Things that we refer to as sense-a-tag and that is passive or semipassive. It has the following functionalities: (a) initiation and generation of query signals for the tags in its proximity, (b) passive detection and decoding of backscatter signals from RFID tags in its vicinity, (c) processing of information that it acquires during its operation, and (d) communication of the collected information by backscattering. The research also involves development of protocols for the sense-a-tags.

Professor Song Wu, Department of Applied Mathematics and Statistics
Students: Fei He, Jianjin Xu

Current Project: Scalable Parallel Processing Algorithms for Sequence Alignment and Assembly
High-throughput next generation sequencing (NGS) technology has quickly emerged as a powerful tool in many aspects of biomedical research. However, along with its rapid development, the data magnitude and analysis complexity for NGS far exceed the capacity and capability of traditional small-scale computing facilities, such as multithreading algorithms on standalone workstations. To address these issues, we try to develop solutions using the ever-increasing supply of processing power by massive parallel processing (MPP) systems. We have designed a scalable hierarchical multitasking algorithm for importing classical sequencing algorithms to modern parallel computers. More specifically, we have developed a novel parallel infrastructure, which includes a portable NGS-oriented messaging package that adapts well to heterogeneous communication systems, and a scheduling package that provides a dynamic balancing strategy for efficient task scheduling. Based on these, a unified software suite, entitled “PPSeq”, has been constructed to import serial bioinformatics algorithms.

Hybrid Network Lab, CEWIT 384
Professor Yuanyuan Yang, CEWIT/Department of Electrical Engineering
Students: Ji Li, Cong Wang
The Hybrid Network Lab performs esearchon multiple topics on wireless and mobile networks, such as static/mobile data gathering and energy replenishment in wireless sensor networks; and packet delivery in mobile ad-hoc networks.
Current Project: Mobile Data Gathering in Wireless Sensor Networks
Static data gathering schemes in wireless sensor networks lead to limited network lifetime since the sensors close to the static data sinks would deplete their energy much sooner than others. In this project, one or more mobile data collectors are employed to gather data from the sensors in the networks. In such mobile data gathering schemes, the routing burden can be partially or fully taken over by the mobile collectors, thus energy can be greatly saved at sensors and the nonuniformity of energy consumption among sensors can be effectively alleviated.

Channel assignment in 802.11n WLAN
We study how to assign channels to APs in 802.11n WLANs, focusing on the new challenges from the 802.11n standard. We first introduce a throughput estimation model. Based on the model, we propose a distributed channel assignment algorithm, in which APs update their channels iteratively to maximize local network throughput. Simulation results show that the proposed algorithm can greatly improve network throughout.
