Research of underwater sensor network routing protocol based on the depth

Underwater sensor network(USN) has a battery replacement, positioning difficult hard, great depth of nodes is poor, traditional routing algorithm of the two-dimensional plane land web is difficult to apply, routing algorithm based on the geographical position, there is also a difficult position and so on characteristics. Based on the above reasons, the existing underwater sensor network routing algorithm based on depth, on the basis of this paper proposes a shake hands first, then send the datagram routing protocol, effectively reduce a lot of redundant data to send, so as to effectively reduce the energy consumption.
