Description
Summary:This paper proposes a novel detection and tracking scheme for large-scale phenomena, called 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 constructs a coarse-grained grid structure and then, once a continuous object appears, fine-grained grid structures are established within coarse-grained grid cells only around the continuous object. The fine-grained grid structures could be constructed with dynamic grid cell size according to various requirements. Secondly, for reliability, minute grid cells of the fine-grained grid structures are able to provide detailed shape of boundary of the continuous object; to quickly deal with diffusion of the continuous object the scheme prepares the fine-grained grid structures into next coarse-grained grid cells toward diffusion direction of the continuous object.
