788.11J Presentation “Active Visitor Guidance System” Presented by Wenjun Gu

The Main Idea A sensor field with some danger areas A user who wants to cross the sensor field with a device that can communicate with sensors Guide a user across a sensor field away from danger area

The Main Achievements Use potential field as a metric for danger Propose a distributed algorithm to propagate danger information and set up a path Give performance bound for the computed path Optimize the delay, communication overhead/balance

The Challenges Asymmetric links Congestion Packet loss Unbalanced communication
