Modified AODV routing protocol in underwater acoustic networks

In the past decade, underwater acoustic networks have attracted more and more research interests and developed broadly for a large number of applications. Due to the characteristics of the underwater medium-low data rate, high bite error rate, unstable link and limited energy of node, the widely accepted routing protocols cannot adapt to the underwater transmission. In the paper, we have compared and analyzed the current routing protocols, and then put forward doubling flooding mechanism and reserving remaining routing mechanism to modify ad-hoc on-demand Distance Vector (AODV). By analyzing the simulation results in the OMNET++, we find modified AODV performs better than traditional AODV in the metrics like packet delivery ratio, route setup time and end-to-end delay.
