Polygon-Based Tracking Framework in Surveillance Wireless Sensor Networks

The authors propose a new tracking framework by organizing nodes into a polygonal spatial neighborhood in order to detect and track unauthorized traversals in surveillance wireless sensor networks. During a tracking, the neighborhood is further constructed ahead of the target traversal, and this features a timely forwarding with guaranteed delivery property. Instead of estimating future movement and position separately in a polygon, they find an original target tracking path in a graph, and create a brink on the graph called "Critical region" by introducing a brink detection algorithm to know a target's route, and to also achieve reliable inter-node communications.
