Devolving an efficient routing protocol in Underwater Wireless Sensor Networks (UWSNs) is a challenge due to volatile characteristics of the underwater environment. In this paper, we proposed an end-to-end delay efficient routing protocol called DVRP (Diagonal and Vertical Routing Protocol for Underwater Wireless Sensor Network). In DVRP, the forwarding of data packets is based on the flooding zone angle by the sender nodes toward the surface sink. To extend the network lifetime, DVRP is deliberating the saving-energy of sensor nodes. The sensor nodes in the network make a local decision of data packets forwarding under the constraint of the flooding angle between them and energy status. Our results show that DVRP has better performance than other existing delay efficient routing protocols, in term of end-to-end delays, energy consumption, and data delivery ratios.
