RESEARCH PROJECTS

DTN for Firefighters: Enabling Delay Tolerant Networking for Mobile Sensors

Sept. 2009-Present: This project aims to equip firefighters with wireless body sensors which can monitor firefighter’s physiological parameters while they are fighting fires. However, wireless connections are often subject to disruptions especially when firefighters are moving frequently in hostile environments. Delay Tolerant Networking (DTN) allows body sensors to buffer data locally and try to upload data opportunistically via nearby team members.

Breadcrumbs for Firefighters: Creating Dynamic Communication Infrastructure

March 2009-Present: The goal of this project is to allow firefighters to carry dispensers and deploy wireless sensor nodes automatically while running into a building. The deployed sensor nodes will work as bread crumbs which then create a dynamic communication infrastructure. Our research focuses on the optimal deployment strategy that strives balance between the number of bread crumbs deployed and the reliability of the crumb chain.

Run-Time Assurance of Application-Level Requirements in Wireless Sensor Networks

Jan. 2009-Present: The current rapid development and deployment of wireless sensor networks (WSNs) and their application in mission critical systems are exacerbating the need for high confidence WSNs. Achieving high confidence WSNs will require new assurance technologies. Most current solutions deal with faults and reliability and not with application level semantics and associated assurances (RTA). We propose the use of a novel WSN design and assurance mechanism, run time assurance, to guarantee that important application-level requirements are met in mission critical applications.

Dependency Constraint Directed Self-Healing for Wireless Sensor Networks

Sept. 2008-March 2009: Current wireless sensor networks (WSNs) is severely short handed in terms of a system's ability to self-heal when failures, security attacks, and performance degradations occur. We present a dependency constraint directed self-healing scheme for WSNs. We explored 4 types of dependency constraints and their impact on self-healing for WSNs. We proposed a self-healing framework and a dependency constraint directed design to deal with these dependencies in self-healing.

BlueGate: A Bluetooth Gateway for Wireless Sensor Networks

Sept. 2008-Jan. 2009: The most convenient wireless interface between the cell phones and sensors is Bluetooth. However, many networked sensor systems use the low power IEEE 802.11.4 instead of Bluetooth. The goal of this project is to create a wireless gateway called "BlueGate" that enables communications between the two types of devices.

AlarmNet: Wireless Sensor Networks for Smart Healthcare

Sept. 2007-Dec. 2009: AlarmNet is an assisted-living and residential monitoring network for smart healthcare research. It opens up new opportunities for continuous monitoring of elders or those in need of medical assistance.

LUSTER: a Wireless Sensor Network for Environmental Research

Sept. 2007-Dec. 2008: LUSTER (Light Under Shrub Thicket for Environmental and Ecological Research) is a developed and deployed wireless sensor network to monitor the impact of sunlight on shrub thicket. The study of sunlight impact is important for ecologists because shrub thickets tend to overwhelm grasslands in many areas of the Earth. LUSTER helps scientists understand this process and evaluate its consequences.
