Abstract :
Accurate and fast nodes locating is required in large-scale emergency logistics with WSN (wireless sensor network) deployed. Under this background, the sensor nodes often move rapidly and frequently, and the mobility of nodes leads to poor reachability to the reference nodes. In this paper, we propose a fast and accurate positioning scheme based on WSN in emergency logistics. Two different wireless sensor networks with 20%+ nodes moving are deployed. Preliminary experiments demonstrate that the efficiency of the proposed system over performed other schemes.
