Overview

Over the past 5 years, Yanyong has built a research program, called PROSE (Providing Robustness to Large-Scale Networked Systems).

Large-Scale Networked Sensor Systems

For many sensor applications, the most important service a sensor network provides is the continuous monitoring of the sensor field, which involves continuously collecting data from physical environment and continuously delivering data to the application. At the same time, sensor systems face many new challenges: sensor nodes have severe energy constraints; network operations can be disrupted by natural reasons such as node failures or congestion as well as malicicous attacks such as radio interference attacks. The objective of this work, therefore, is to deliver the required service under varying network conditions.

• TARA: Topology-Aware Resource Adaptation for Congestion Control in Sensor Networks
• PARIS: A Framework for Privacy Augmented Relaying of Information from Sensors
• DARWIN: Defenses for Attacks of Radio interference in Wireless Networks
• RollCall: A Low-Cost Asset Tracking System Using Transmit-Only RFID Tags

Large-Scale Parallel Systems and Clusters

High-performance systems mainly serve large-scale, long-running scientific and engineering applications, which require maximized system utilization and minimized job response times. As both the applicattions and the underlying platforms scale to thousands of processors, failures become a norm rather than an exception. As a result, instead of preventing failure occurrences, we seek to to provide "graceful" operations under faulty conditions by mitigating the adverse impact of failures.
