Bottom Line: More specifically, cooperative routing has not yet been jointly considered with sink mobility.Therefore, this paper aims to enhance the network reliability and efficiency via dominating set based cooperative routing and sink mobility.The proposed work is validated via simulations which show relatively improved performance of our proposed work in terms the selected performance metrics.

ABSTRACT
Performance enhancement of Underwater Wireless Sensor Networks (UWSNs) in terms of throughput maximization, energy conservation and Bit Error Rate (BER) minimization is a potential research area. However, limited available bandwidth, high propagation delay, highly dynamic network topology, and high error probability leads to performance degradation in these networks. In this regard, many cooperative communication protocols have been developed that either investigate the physical layer or the Medium Access Control (MAC) layer, however, the network layer is still unexplored. More specifically, cooperative routing has not yet been jointly considered with sink mobility. Therefore, this paper aims to enhance the network reliability and efficiency via dominating set based cooperative routing and sink mobility. The proposed work is validated via simulations which show relatively improved performance of our proposed work in terms the selected performance metrics.

f2-sensors-15-14458: Rule 3: DD <DR <DS.

Mentions: DD < DR < DS where DD, DR and DS represent depth of destination, relay and source nodes respectively. This relation shows that source, relay and destination nodes are present at highest, medium and lowest depth regions in any Rk, respectively. Rule 3 is shown in Figure 2. We assume that MSs are periodically transmitting beacon signals because of which nodes are aware of their mobility pattern and are forwarding data accordingly.
