Simulation study on self-reorganization of Underwater Acoustic Networks

Security is one of the ultimate goals of Underwater Acoustic Networks. The security considerations must be carried out during the construction of the network. But at the worst conditions, the network may be destroyed by adverse attacks. It must be restored in some extents for continuous usage. For restoring, self-reorganization is an efficient measure to be taken. During the procedure, several steps should be adopted. The first step is to evaluate the extent of being ruined, which will determine whether it is valuable to perform subsequent reorganization. The next is to analyze the causations of the destroying, and this will support the reorganization. After the above steps, practices on self-reorganization of Underwater Acoustic Networks are presented. Inside there are mainly topology adjustment and protocol adjustment. Simulation of the presented method is carried out using Opnet. The results show that the adjustments are efficacious.
