Effective solutions should be devised to handle the effects of shadow zones in
Underwater Wireless Sensor Networks (UWSNs). An adaptive topology reorganization
scheme that maintains connectivity in multi-hop UWSNs affected by shadow zones has
been developed in the context of two Spanish-funded research projects. A mathematical
model has been proposed to find the optimal location for sensors with two objectives: the
minimization of the transmission loss and the maintenance of network connectivity. The
theoretical analysis and the numerical evaluations reveal that our scheme reduces the
transmission loss under all propagation phenomena scenarios for all water depths in
UWSNs and improves the signal-to-noise ratio.
