Minimizing localization cost with mobile anchor in underwater sensor networks: extended abstract |
Abstract | ||
|---|---|---|
In underwater sensor networks (UWSNs), it is important to know the position of each sensor node to identify the place of event in the target ocean field. Ling et al. proposed a localization method that estimates the positions of sensor nodes based on trilateration from distances to anchors with accurate positions and the sensor nodes whose positions have already been estimated [1]. This method lacks the accuracy of estimated positions, since the estimation error is accumulated while new anchors are generated one after another. Erol et al. proposed the localization method using special buoys that can dive and surface in water[2]. Each buoy gets the location information by GPS while it is on the water surface. It can also dive and send the information to the neighboring underwater sensor node by the acoustic beacon to measure the distance. This method achieves accurate position estimation, but takes high cost because many buoys need to be deployed. |
