Popis: The design of routing protocols for Underwater Wireless Sensor Networks (UWSNs) holds many challenges, due to long propagation, high mobility, limited bandwidth and multi path routing. As a consequence of the occurrence of the void hole, and uneven distribution of nodes in the network, the selection of next forwarding in one hop or even two hops may result in failure of forwarding in indigenous sparse deployment region. In order to reduce the probability of occurrence of void hole this protocol presents Single Hop Selection based Forwarding WDFAD-DBR (SHSF-WDFAD-DBR), which selects at least two optimal forwarder nodes in the communication range to reduce the probability of occurrence of void hole and it also avoids the backward transmissions. In addition the mechanism of forwarding area division and neighbor node prediction mechanism is proposed to reduce the energy consumption caused by duplicate packets and neighbor request. Finally the simulations are conducted to verify the efficiency and legitimacy of SHSF-WDFAD-DBR with respect to Packet Delivery Ratio (PDR) and energy tax.
