Detection and Tracking of Dynamic Amorphous Events in Wireless Sensor Networks

Speaker:  Qi Han – Golden, CO, United States
Topic(s):  Networks and Communications

Abstract

In recent years, wireless sensor networks (WSNs) have been deployed for various applications such as environmental monitoring, structural health monitoring, and emergency responses.  Using WSNs to detect and track interesting events has been a chief problem.  Events can be either point events, with an exact location and constant shape, or region events, which cover a large area and have dynamic shapes. While both of these types of event have received attention, no event detection and tracking algorithm in existing research is able to identify and track region events which may be created or destroyed through splitting and merging.  In this talk, I will first describe DRAGON, an event detection and tracking algorithm that is able to handle all types of events including region events with dynamic identities. I will also present a few technical details on AWARE, a network protocol that maintains the underlying communication structure adaptive to the dynamic amorphous events being tracked.
