چکیده
|
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. we consider the issue from not only the physical layer,but also at the node processing layer by incorporating a tracking solution. we present simulation results,testing results in a swimming pool featuring both stationary and moving receivers,and results from a lake test with a mobile receiver. copyright © 2012 patrick carroll et al.
