Failure tolerance analysis of a small scale underwater sensor network with RF electromagnetic communications

A small scale wireless sensor network was designed using electromagnetic technology in order to provide an underwater coastal monitoring service. The sensor nodes were deployed manually, which formed a multi-hop static topology for the network. Data delivery was scheduled via daily cycles of sleeping and waking-up. Due to the unique features of the network, Ad-hoc On-demand Distance Vector was chosen as the routing protocol. Modeling and simulations were conducted to evaluate network performance in terms of failure recovery and network re-convergence. The results demonstrated a certain level of failure tolerance of the designated network for this and similar scenarios.
