In an underwater wireless sensor network (UWSN), the location of the sensor
nodes plays a significant role in the localization process. The location
information is obtained by using the known positions of anchor nodes. For
underwater environments, instead of using various static anchor nodes, mobile
anchor nodes are more efficient and cost-effective to cover the monitoring
area. Nevertheless, the utilization of these mobile anchors requires adequate
path planning strategy. Mzost of the path planning algorithms do not
consider irregular deployment, caused by the effects of water currents.
Consequently, this leads towards the inefficient energy consumption by
mobile anchors due to unnecessary transmission of beacon messages at
unnecessary areas. Therefore, an efficient dynamic mobile path planning
(EDMPP) algorithm to tackle the irregular deployment and non-collinear
virtual beacon point placement, targeting the underwater environment
settings is presented in this paper. In addition, EDMPP controls the
redundant beacon message deployment and overlapping, for beacon message
distribution in mobile assistant localization. The simulation results show that
the performance of the EDMPP is improved by increasing the localization
accuracy and decreasing the energy consumption with optimum path length.
