Dynamic CDBR for Underwater Wireless Sensor Networks

The UWSN has found their place in many applications like sea exploration, flood detection and many more. The sensor nodes used in UWSN are installed with specialized depth sensors to compute the depth value of itself with respect to sink that is deployed at the surface. Obviously, to transfer data by sensor nodes to sink, some routing protocol is necessary for communication. There are many routing protocols like DBR, CDBR, VBF, ICRP, DDD, H2H-DAB and many more. Some of them need location information while some need depth data to make routing decision to forward data. Since CDBR protocol is implemented for static network topology, in this paper, CDBR for dynamic network topology means the positions of the sinks keeps on changing with successive rounds is implemented. The simulations are done in MATLAB and simulation graphs are drawn for network lifetime, packets transferred, end to end delay and remaining energy. The graphs show that the proposed algorithm outperforms the existing algorithm.
