Topology structure design for underwater acoustic Wireless Sensor Network

Topology structure for UAWSN has to be of general characters of WSN not only, but also consider the limited communication range and cell energy, the effect of single damaged cell to the whole network and so on. This paper analyzes the energy efficiency for UAWSN theoretically and then presents the simulation results for square and triangle topology structures with different network scale. All these researches show that the energy efficiency of UAWSN is greatly related to the topology structure. With the increase of the network scale (K) much energy is wasted on relays which results to the decrease of the energy efficiency. If the structure scale is fixed and unchanged the energy efficiency of square topology structure is higher than that of triangle.
