Adaptilve Data Collectilon Scheme for Trackilng Mobille Target in Wireless Sensor Networks

Tracking mobile targets is an important application of wireless sensor networks. However, mobility of the target brings new challenges to designing energy-efficient and scalable data collection schemes. A novel dynamic grid-based tracking (DGT) scheme for tracking mobile target is proposed in this paper. This scheme is distributed in nature, and can be adaptive to the mobility of the target. The underlying idea of embedding a virtual grid structure and restricting mobility-related choices to grid nodes can be generally applied to other wireless sensor networks applications, where mobility is an important consideration during protocol design
