  • Practical robust localization over large-scale 802.11 wireless networks  
  • by Andreas Haeberlen, Algis Rudys — 2004 — In Proceedings of the Tenth ACM International Conference on Mobile Computing and Networking (MOBICOM
  • …We demonstrate a system built using probabilistic techniques that allows for remarkably accurate localization across our entire office building using nothing more than the built-in signal intensity meter supplied by standard 802.11 cards. While prior systems have required significant investments of …

  • Enforcing Java Run-Time Properties Using Bytecode Rewriting  
  • by Algis Rudys, Dan S. Wallach — 2002 — In International Symposium on Software Security
  • …Bytecode rewriting is a portable way of altering Java's behavior by changing Java classes themselves as they are loaded. This mechanism allows us to modify the semantics of Java while making no changes to the Java virtual machine itself. While this gives us portability and power, there are numero…

  • Transactional Rollback for Language-Based Systems  
  • by Algis Rudys, Dan S. Wallach — 2002 — In ISOC Symposium on Network and Distributed Systems Security (SNDSS
  • …Language run-time systems are routinely used to host potentially buggy or malicious codelets --- software modules, agents, applets, etc. --- in a secure environment. A number of techniques exist for managing access control to system services and even for terminating codelets once they've been determ…

  • Termination in Language-based Systems  
  • by Algis Rudys, John Clements, Dan S. Wallach — 2002 — ACM Transactions on Information and System Security
  • …Language runtime systems are increasingly being embedded in systems to support runtime extensibility via mobile code. Such systems raise a number of concerns when the code running in such systems is potentially buggy or untrusted. While sophisticated access controls have been designed for mobile cod…

  • Garbage collector memory accounting in language-based systems  
  • by David W. Price, Algis Rudys, Dan S. Wallach — 2002 — In IEEE Symposium on Security and Privacy
  • …Language run-time systems are often called upon to safely execute mutually distrustful tasks within the same runtime, protecting them from other tasks ’ bugs or otherwise hostile behavior. Well-studied access controls exist in systems such as Java to prevent unauthorized reading or writing of data, …

  • Wireless LAN Location-Sensing for Security Applications  
  • by Ping Tao, Algis Rudys, Andrew M. Ladd, Dan S. Wallach — 2003
  • …This paper considers the problem of using wireless LAN locationsensing for security applications. Recently, Bayesian methods have been successfully used to determine location from wireless LAN signals, but such methods have the drawback that a model must first be built from training data. The introd…

  • Using Wire  
  • by Ieee Rjs Int, Andrew M. Ladd, Kostas E. Bekris, Guillaume Marceau, Algis Rudys, Dan S. Wallach, Lydia E. Kavraki — 2002
  • …IEEE 802.11b wireless Ethernet is rapidly becoming the standard for in-building and short-range wireless communication. Many mobile devices such as mobile robots, laptops and PDAs already use this protocol for wireless communication. Many wireless Ethernet cards measure the signal strength of incomi…

  • On the Feasibility of Using Wireless Ethernet for Indoor Localization  
  • by A. Ladd, ..., Kostas E. Bekris, Algis P. Rudys, Dan S. Wallach, Lydia E. Kavraki — 2004 — IEEE Transactions on Robotics and Automation
  • …IEEE802.11b wireless Ethernet isbu19803 the standard for indoor wireless communication. This paper proposes the use of measured signal strength of Ethernet packets as a sensor for a localization system. We demonstrate that off-the-shelf hardware can accuratelyb used for location sensing and rea…

  • Robotics-Based Location Sensing Using Wireless Ethernet  
  • by Andrew M. Ladd, Kostas E. Bekris, Algis Rudys, Lydia E. Kavraki, Dan S. Wallach — 2005 — Wireless Networks
  • …A key subproblem in the construction of location-aware systems is the determination of the position of a mobile device. This article describes the design, implementation and analysis of a system for determining position inside a building from measured RF signal strengths of packets on an IEEE 802.11…
