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.
