E-DSDV routing protocol for mobile ad hoc network for underwater electrocommunication

Dear editor, We realized the dynamic networking of underwater electro-communication for the first time through experiments[1-3].The E-DSDV routing protocol based on underwater electro-communication also belongs to the proactive routing proto-col[4].In the E-DSDV protocol,each node needs to estab-lish and maintain a routing table,which contains the source node,destination node,next-hop node,the total number of hops to the destination node,and node sequence num-ber[5-7].The E-DSDV protocol can transform the voltage signal detected at the receiver and transmitter into the dis-tance information between neighbors on time and the dis-tance information between neighbors into the sequence num-ber required in the protocol.After topology transformation of nodes in the network,they can update their sequence numbers in time and give the updated information to neigh-bors,so as to change the routing information of the network and timely change the routing table to maintain accurate routing information.The principle of the E-DSDV protocol is as follows.
