Software Defined Networking (SDN): [project page]
We are researching many aspects of SDN, including use of SDN APIs at Internet peering points and use of SDN in home networks. Refer to our recent publications for more details, and to video links (part1: Skype, part2: YouTube, part3: FaceBook) that demonstrate our solutions. We are also setting up an SDN alliance for the Australia New Zealand region.
Securing the Internet-of-Things (IoT): [project page]
We are researching how residential and commercial devices for the Internet-of-Things (IoT) can be secured at the network layer.
Security for Wearable Healthcare Devices: [project page]
We are researching how wearable healthcare monitoring devices can be secured.
Pollution Monitoring (HazeWatch): [project page]
This project aims to implement an urban air pollution monitoring system in which users carry small portable measurement devices and upload the data in real-time using an app on their mobile phones. Refer to the link below for more details, and see our live pollution maps here.
Liveability: [project page]
This project uses an iPad app to collect data from older citizens regarding aspects of the built environment that affect their quality of life.
Networks with Small (Optical) Buffers:
This research develops addresses the feasibility of core networks in which routers have very small buffering capacity, say in the range of 10-50 packets. This is particularly interesting for optical packet switched (OPS) networks in which routers are expected to have all-optical buffering. Our research addresses several aspects:
This research addresses the feasibility of core networks in which routers have very small buffering capacity, say in the range of 10-50 packets. This is particularly interesting for optical packet switched (OPS) networks in which routers are expected to have all-optical buffering. Our research addresses several aspects:
- We develop novel edge traffic conditioning mechanisms that help reduce loss in the small core buffers. In the context of OPS networks, we have developed an analytic and simulation framework to evaluate the efficacy of edge traffic conditioning. Our contributions in this area have appeared at ATNAC'04, HPSR'05, Infocom'06, and a journal version is under review. The supporting simulation code is available here.
- We develop an understanding of the performance of TCP traffic in networks with very small buffers. Our contributions in this area have appeared in ICoN'06 and ANTS'07.
- We show an interesting phenomenon when TCP and real-time traffic are multiplexed at links with small buffers: there exists a regime in which loss for real-time traffic goes up with increasing buffer size. Our study of this phenomenon has appeared in Infocom'08 (Student Workshop) and at IWQoS'08.
Dynamic Power Control in Body Area Networks:
This research evaluates the benefits of dynamically adapting the radio transmit power in body-wearable devices with very limited energy reserves. Our contributions in this space have appeared in BodyNets'08 and extended version is under review by a journal. Experimental traces used for these papers are available here, please view the contained "README.pdf" file for interpretation of the trace files.
Security in Wireless Sensor Networks:
This research develops and analyses mechanisms for secure broadcasts in wireless sensor networks. Our contributions in this are have appeared in PIMRC'07, WiSEC'07, and PIMRC'08.
Mobility and Routing in the Soccer Field:
This research develops protocols for live monitoring of soccer players during a match. The applet on this page helps visualise inter-connectivity of soccer players of the first-division UNSW soccer club in their game played on 5 Feb 2009. More details are available in the sections below. Data from the following games can be visualised:
