Increased Throughput DB-EBH Protocol in Underwater Wireless Sensor Networks

The characteristics of underwater sensor networks are unique and they are much different from terrestrial networks but the importance of both cannot be neglected. However it is much more difficult to sustain a workable environment underwater due to its harsh characteristics which make tasks such as batteries replacement, nodes repairing and other similar factors difficult. Thus the need to efficiently utilize the energy of the nodes remain a key aspect in the advancement of Underwater Sensor Networks (UWSNs). Due to reasons as such we present an improved version of DB-EBH which was previously an advancement on EBH. Just like the previous two techniques, IT DB-EBH is also a hybrid network. The nodes are selected on basis of Selection Criteria Phase. Direct transmission is only used when a node cannot identify a neighbor in its transmission range and outside a defined threshold value.
