ii) This approach involves more manual work therefore not suitable for UWSN.
H2-DAB [36] is a dynamic addressing scheme for UWSNs routing while ROLS [20, 43] is a static addressing scheme and its updated model [44]considers UW-LSNs routing issue which propose hexadecimal addresses for the heterogeneous types of nodes.
For shallow-water coastal areas, a quasi-stationary 2-dimensional UWSN architecture has been considered.
Figure 7 presents the general classification of routing protocols for UWSN.
UWSN will utilize the services of its network of nonprofit partner agencies to identify and administer Project REACH assistance.
Routing protocols for UWSN have been presented in section 3.
There are two types of sensors used in UWSN namely, sink nodes and ordinary nodes [15, 16].
Since existing protocols designed for terrestrial networks are also modified for use in UWSN, the constraints mentioned above demand for protocols specifically designed for UWSN.
In this article, the work on routing layer of UWSN is presented in detail.
It is used to synchronize nodes in a cluster based UWSN.
However, all these schemes are still not efficient enough for UWSNs and are effective only against the adversary that is relatively weak and easy to overcome.
We must consider more parameters for each sensor node such as mobility, deployment localization, and indirect consider UWSNs security.
