Abstract—The paper presents a tree-based routing approach for Underwater Wireless Sensor Networks (UWSN). The proposed approach uses pre-constructed shortest-path trees in a virtual 3D grid topology to obtain routing paths between source and sink nodes in the UWSN. Due to the availability of these pre-constructed shortest-path trees connecting the occupied cells of the 3D grid, the proposed protocol offers higher routing path stability compared to other protocols that rely on costly.
