Virtual Path Based Routing Scheme for UWASN

Underwater acoustic sensor networks (UWASN) is a key technology for the ocean exploitation. Routing schemes specially designed for it are urgently needed. In this paper, we consider energy aware and energy balance routing schemes and aim to prolong network lifetime. By introducing the concept of “virtual path”, we propose a routing scheme named virtual path based routing, which gets more global information, especially the energy information, in a local and distributed way. Simulations show that our scheme can balance the energy consumption and prolong the network lifetime with no loss of the network performance.
