Research

My research is focused on Multihop Wireless Networks. Specifically, I am interested in looking at ways to improve the reliability and performance of 802.11 and 802.15.4 based multi-hop networks.

Projects

• Wireless Single Channel Full-Duplex Radios This project explores the design of a single channel full-duplex wireless transceiver. The design uses a combination of RF and baseband techniques to achieve full-duplexing with minimal effect on link reliability. Experiments on real nodes show the full-duplex scheme achieves a median gain of 84% in aggregate throughput as compared to traditional half-duplexing wireless for a single hop network.
  This project introduces Antenna Cancellation, a novel technique for self-interference cancellation. In conjunction with existing RF interference cancellation and digital base- band intereference cancellation, antenna cancellation achieves the amount of self-interference cancellation required for full- duplex operation.
  Their are significant potential MAC and network gains with full-duplexing A full-duplex system can solve some important problems with existing wire- less systems including hidden terminals, loss of throughput due to congestion, and large end-to-end delays. More details in the Mobicom 2010 and Mobicom 2011 papers.

• Stanford Wireless Access Network (SWAN) The Stanford Wireless Access Network (SWAN) project aims to study and implement existing techniques for setting up mesh networks and research into extending those techniques for improved performance. Experiments have shown that although current protocols are able to form routes and route data in the network, the performance falls below what would be expected of a production network. Especially with multiple streams active, delivery reliability and performance are unacceptable for an office environment. Further, experiments on SWAN also show that existing rate selection algorithms fail miserably in mesh networks. A lot of the times, self interference can lead to bad link estimates and cause transmitters to switch to the lowest transmission rate, thus wasting valuable channel time and reducing throughput. The SWAN project conducts research into improving routing, link estimation and adaptive transmit parameter selection for creating a production class wireless mesh network.

• Stanford Wireless Analysis Tool (SWAT) SWAT is an open source Wireless measurement tool that runs experiments on user’s testbed, analyzes several properties of the network and generates a report on the analysis. Users can configure the experiments to their needs. You can download it from the SWAT website.

• The MNet Architecture The MNet architecture explores how to architecturally improve sensor networking. The core principle of the architecture is to minimize the energy cost of diagnosing network behavior, transforming the typical “black box” embedded sensornet to a well-understood and transparent system that is easy to optimize, manage, and deploy.
