Abstract
In this paper, we investigate the problem of localizing an underwater sensor node based on message broadcasting from multiple surface nodes. With the time-of-arrival measurements from a DSP-based multicarrier modem, each sensor node localizes itself based on the travel time differences among multiple senders to the receiver. Using one-way message passing, such a solution can scale to accommodate a large number of nodes in a network. Continuing on our preliminary work in [1], we in this paper focus on the tracking solutions at the node processing layer. We present simulation results as well as testing results in a swimming pool with both stationary and moving receivers.
