Abstract
Current underwater communication typically includes acoustic, optical, radio frequency, and magneto-inductive channels. Wireless sensor networks are usually built on these four channels. However, these underwater networks are vulnerable to complex aquatic environments. In nature, weakly electric fish are able to communicate electrically (called electrocommunication), which is ‘invisible’ to most other animals, to convey information such as species, courtship, and environmental conditions. Inspired by the electrocommunication of weakly electric fish, an artificial electrocommunication system that uses an electric induction (EI) channel has been developed recently. This paper further develops an underwater networking system using the EI channel, which addresses the solutions to collision avoidance and routing problems during electrocommunication networking. In particular, a CSMA/CA-based electrocommunication mechanism was used to solve the collision problem. Then, a single-hop underwater electrocommunication network (UEN) was established. Furthermore, a complex multi-hop UEN was implemented on the basis of the ad hoc on-demand distance vector routing protocol. Theoretical analysis, simulations, and experiments were conducted to demonstrate the effectiveness of the developed UEN. Extensive results show that the UEN holds the potential to serve as a complement to future underwater wireless sensor networks.
