Design and Development of Heterogeneous Underwater Sensor Networks

摘要

Limited bandwidth capacity and battery power are the unique characters of Underwater Sensor Networks (UWSNs). First this study introduces a competition scheme based on delay time. This scheme provides a selection method of relay nodes considering the limited bandwidth capacity. Then a heterogeneous nodes distribution strategy is proposed to balance the energy consumption of the whole UWSN. The ratio between the node initial energy of the adjacent annuluses is analyzed in a circular UWSN. Simulation results validate this design.
