    • Diagnosing Wireless Packet Losses in 802.11: Separating Collision from Weak Signal 

      Rayanchu, Shravan; Mishra, Arunesh; Agrawal, Dheeraj; Saha, Sharad; Banerjee, Suman (University of Wisconsin-Madison Department of Computer Sciences, 2007)
      It is well known that a packet loss in 802.11 can happen either due to collision or an insufficiently strong signal. However, discerning the exact cause of a packet loss, once it occurs, is known to be quite difficult. In ...

    • Load Balancing in Large-Scale RFID Systems 

      Dong, Qunfeng; Shukla, Ashutosh; Shrivastavam, Vivek; Agrawal, Dheeraj; Banerjee, Suman (University of Wisconsin-Madison Department of Computer Sciences, 2006)
      Large-scale radio frequency identifer (RFID) systems are being increasingly deployed in many applications such as supply chain automation. An RFID system consists of inexpensive, uniquely-identifiable tags that are mounted ...

    • Towards Robust Firewalls Using Approximate Packet Classification 

      Dong, Qunfeng; Agrawal, Dheeraj; Ge, Zihui; Wang, Jia; Wu, Jianming; Banerjee, Suman (University of Wisconsin-Madison Department of Computer Sciences, 2007)
      During the past decade or two, the Internet has witnessed an ever escalating demand for protection against unwanted traffic, including those carrying out malicious attacks. Packet filtering has been universally deployed ...

    • Wire Speed Packet Classification Without TCAMS: One More Register (and a Bit of Logic) is Enough 

      Dong, Qunfeng; Banerjee, Suman; Wang, Jia; Agrawal, Dheeraj (University of Wisconsin-Madison Department of Computer Sciences, 2006)
      Many Internet functions, such as QoS and security, require classification of each packet based on a set of rules. As Internet bandwidth and data transmission rates continue to grow, the available time budget to classify ...
