This paper proposes a novel detection and tracking scheme for continuous objects in wireless sensor networks, such as wild fire and bio-chemical material. Unlike previous works, the scheme takes into account a two-tier grid structure in order to achieve flexible and reliable detection and tracking. Firstly, for flexibility, the scheme proactively constructs a coarse-grained grid structure and then,...
This paper addresses issues for tracking and monitoring continuous objects, such as poison gas, biochemical, and chemical liquid in wireless sensor networks. These continuous objects are quite different from the individual objects, such as people, animals, and vehicles in that they are continuously distributed across a region and usually occupy a large area. Accordingly, they are detected and sensed...
Most existing routing protocols on the object detection and tracking in sensor networks concentrates on finding ways to detect and track one or more individual objects, such as people, animals, and vehicles, and not many protocols have been done on detecting and tracking continuous objects, such as poison gas, biochemical, and chemical liquid. These continuous objects are quite different from the...
